The Chevrolet Suburban is a large sport utility vehicle from Chevrolet. It is the longest continuous use automobile nameplate in production in the world, starting from 1934 for the 1935 U.S. model year, and has traditionally been one of General Motors' most profitable vehicles. The Suburban has been produced under the Chevrolet, Holden, and GMC marques until the GMC version was rebranded as the GMC Yukon XL. For most of its recent history, the Suburban has been a station wagon-bodied version of the Chevrolet pickup truck, including the Chevrolet C/K and Silverado series of truck-based vehicles. Cadillac offers a version called the Escalade ESV.

History[edit]

Several automotive companies in the United States used the "suburban" designation to indicate a windowed, station wagon type body on a commercial frame including Dodge, Plymouth, Studebaker, Nash, Chevrolet, and GMC. Chevrolet began production of its all-steel "carryall-suburban" in 1935. GMC brought out its version in 1937. These vehicles were also known as the "Suburban Carryall" until GM cut the name to simply "Suburban."

GMC's equivalent to the Chevrolet model was originally named "Suburban" as well, until re-branding it to "Yukon XL" for the 2000 model year.

With the end of production of the Dodge Town Wagon in 1966 and the Plymouth Suburban station wagon in 1978, only General Motors continued to manufacture a vehicle branded as a "Suburban", and GM was awarded an exclusive trademark on the name in 1988. The Chevrolet Suburban is one of the largest SUVs on the market today. It has outlasted competitive vehicles such as the International Harvester Travelall, Jeep Wagoneer, and the Ford Excursion. The latest competitor is the extended Ford Expedition EL, which replaced the Excursion.

The Suburban of today is a full-size SUV with three rows of seating, a full pickup truck frame, and V8 engine. It is one of the few station wagons available with all bench rows. The Suburban is the same height and width as the Chevrolet Tahoe, although the Suburban is 20 inches (510 mm) longer. The extra length provides a full-sized cargo area behind the 9 passenger seating area.

In recent years, the Suburban has been used as a police car, fire chief's vehicle, or EMS fly-car. Suburbans are also used as limousine. The United States Secret Service uses black Suburbans, and operates fully armored versions for the President of the United States when he attends less formal engagements.

In the late 1990s, GM also introduced a RHD version of the Suburban, badged as a Holden, for the Australian market. Sales were low and GM withdrew the model in 2000 from Holden's lineup.

Chevrolet offered the body style as a "Carryall Suburban". It shared the front sheetmetal and frames of the 1/2 ton pickup models of the same year, but featured all-metal wagon bodies differing very little in shape from contemporary "woodie" wagons. Seating for up to eight occupants was available, with three in front row, two in the middle row, and three in the rear row. Either the side-hinged rear panel doors or a rear tailgate/lift window could be selected for cargo area access.

Suburbans were built in model years 1941, 1942, and 1946. It was produced during the war as a military transport vehicle.[1] Seating for up to eight occupants was available. Models with rear panel doors were designated "3106," while those with tailgates were designated "3116." The Chevrolet versions were equipped a 216-cubic-inch 6-cylinder engine. The GMC version was equipped with a 228-cubic-inch 6-cylinder engine.

Beginning in 1953, the Hydra-Matic 4-speed automatic transmission was available in GMC models and in the 1954 model year Chevrolet Suburbans. Models with rear panel doors were designated "3106," while those with tailgates were designated "3116." In 1952, the Suburban came with either a tail gate or panel doors.[1] The front bench seat was split, with two seats on the drivers side and a single seat on the passenger side, which slid forward for access to the rear two rows of seats. The second row was a "2/3" seat, requiring occupants to move past the front passenger seat, as well as the second row seats to access the third row.

This was the last series to feature "Canopy Express" models.

The design of the 1949 Suburban would go on to inspire the design of the Chevrolet HHR over half a century later. (THE EXAMPLE PICTURED IS CUSTOM AND NOT REPRESENTATIVE OF WHAT GM PRODUCED)

Updated engineering and styling on Chevrolet trucks was not introduced until March 25, 1955, in the middle of the model year. All Chevrolet truck models received new styling that included a flatter hood, front fenders flush with the body, and a trapezoid grill.[1] The trucks' V-shaped speedometer was shared with passenger car models.[8]

Engines included I-6 and the small block V8s. Chevrolet used its 265 V8 engine, later evolving it to a 283-cubic-inch version. GMC based their V8 on a Pontiac design. Standard Suburban model numbers continued from the previous series, but the introduction of four-wheel-drive models in 1957 added the numbers "3156" for 4WD Suburbans with panel doors, and "3166" for 4WD Suburbans with tailgates.

The styling of the 1960 - 1961 model year took cues from the late 1950s Chevrolet cars and had large oval ports above the grille. Front independent suspension was new for 1960.[10] The cab featured a "wrap around" windshield. Both tailgate and panel doors rear openings were available. From 1962 onwards, the hood styling was more conservative, with hoods that eliminated the large ports. In 1964, the front glass area was updated to a flatter windshield, and larger door glass. 1,150 lb (520 kg) of cargo could be carried in the back.[11]

This model series introduced a factory-equipped 4WD ("K") option for the first time. The 2WD "C" models introduced a torsion bar-based independent front suspension and trailing arm and coil spring rear. But by 1963, returned to a more conventional coil-spring approach.

Engines included both I-6 and small-block V8s. A 305 cu in (5.0 L) GMC V6 engine was also available on GMC models. This 305 was actually from GMCs medium-duty truck line. It featured high torque, but was also notable for poor fuel economy. Transmissions were a 3-speed and 4-speed manual, and the automatic Powerglide.

A 15-passenger conversion was done by Stageway of Fort Smith, Ark. These modified Suburbans had three doors on the right, a 171 in (4,343 mm) wheelbase, were 273 in (6,934 mm) long, and weighed 6,300 lb (2,858 kg).[1]

One ton (C-30), 10-foot (3 m) panel truck models were no longer available after 1966.

The second generation C/K Suburbans are recognised by having only a single drivers side door and two passenger-side doors. They were available in both 2WD and 4WD models.

Engines included the V6 (e.g., Chevrolet 292-cubic-inch I6, and GMC 305 cubic inch V6), and small-block V8s of the current model year (e.g., 283, 307, 327, 350, 400-cubic-inch V8s.) For the first time, a three-quarter ton version was available.

This series would also be the last to offer C-10 & C-20 panel truck models for commercial purposes, the last year being 1970.

1971 saw the introduction of disc brakes on the front wheels,[15] and 1972 was the last year for coil-spring rear suspension on 2WD models. 1972 also introduced a smaller housing for the rear seat air conditioning (a unit that ran the full length of the roof had been available since 1967). The Comfort-Tilt steering wheel became optional in 1971.[16]

Brazilian version[edit]

In 1964, Chevrolet in Brazil introduced a 5-door version of the Suburban called Veraneio (also known as C-14/16). It was based on the 1960-66 US C/K series. The Veraneio used the instrument cluster from the C/K series although the exterior sheet metal layout is exclusive to Brazil. They were initially powered with a Chevrolet 4.2 L inline six based on the pre-1962 "Stovebolt" engines. Later they used the 250-cid 4.1 L engine from Chevrolet's Brazilian mid-size sedan - the Opala. The original version of the Veraneio was kept in production, with another grille and interior, until 1988 (model year 1989), but it was eventually replaced with an updated version based on the C-20 family.

In 1997 GM introduced in Brazil the Silverado pickup, replacing the "C Series". The Brazilian version of the Suburban, which was made in the same style of the 1992 American Tahoe until 2001, was called the Grand Blazer, a successor to the Veraneio. The 4.1 L inline six engine with 138 hp (103 kW) was offered on both models with option for a MWM 4.2 L turbodiesel unit with 168 hp (125 kW).

With the third generation Rounded-Line C/K models, the Suburban became a 4-door vehicle.[17] The Rounded-Line 1970s body style remained largely unchanged for 19 model years - making this series the longest Suburban generation in production. Both 2WD and 4WD models, designated "C" and "K", were offered, as well as one-half ton and three-quarter ton models ("10" and "20" on the Chevrolet models, "1500" and "2500" on GMC models). The one-ton model designation was the C or K 30 for GMC and 3500 for Chevrolet.

Suburbans for model year 1973[18] now had two doors on each side (the previous generation had just one door on the driver's side), front-and-rear air conditioning, a baggage rack, a heater under the third seat and step-plates for easier access.[19] A new Eaton Automatic Differential Lock was introduced as an option extra for the rear differential.

The base engine was the small-block 305-cubic-inch V8. A 350-cubic-inch V8 and a 400-cubic-inch V8 were optional. The 454-cubic-inch big-block V8 was now available for the first time. The 6.2 L (379 cu in) 130 hp (97 kW) Detroit Diesel V8 engine was also available from 1982-onwards.[20] The Diesel later became the engine of choice for Suburbans exported to Europe from USA.

Three-speed Turbo Hydra-Matic 350 automatic transmissions were available for only small block engines. The Turbo Hydra-Matic 400 was used for big block and 6.2 diesel engines. The four-speed Turbo Hydra-Matic 700R4 was introduced in 1981 and was available with the small block and the 6.2 diesel. Towing packages, with axle gear reduction and cooling additions for heavy loads, were optional.

Trim options included base level and upgraded Silverado versions. An optional 3rd row bench seat allowed for 9-passenger configurations. A rear heating system was optional.

In 1981, automatic locking front hubs were added for shift-on-the-move four-wheel drive models, and the NP208 transfer case replaced the NP205 in most models.[21]

In 1984, asbestos was removed from rear brakes. For 1985, a new grille was used.[22] A total of 64,670 Suburbans were made in 1985.[22]

In 1986 and 1987, the method of fuel delivery for the engines was switched from carburetors to electronic fuel injection. The system that GM chose was called throttle body injection, or TBI. Suburban gained rear-wheel anti-lock braking system (ABS) for the 1990 model year. A heavy-duty four-speed automatic transmission, the 4L80-E was added in 1991.

GM temporarily changed the usual "C/K" designation to "R" and "V" for the 1987 through 1991 model years. This was done to avoid confusion with the GMT400-based Chevrolet C/K pickup trucks, which were introduced in 1988, during the overlap period.

The GMT400-based Suburbans were introduced in the 1991 model year. The similar pickup truck models had switched to the newer platforms in the 1988 model year. Both 2WD and 4WD models, designated "C" and "K", were offered, as well as half ton and three-quarter ton ("1500" and "2500") models.

The base engine for all variants was the small-block 5.7 L (350 cu in) V8. The big-block 7.4 L (454 cu in) V8 was optional for the 2500 series. The optional 6.5 L Turbo diesel was available on all models - though rare on the 1500 series. The 6.5 L Turbo diesel used in the Tahoe was detuned to 380 lb·ft (520 N·m) torque due to the limitation of the 8.5-inch (220 mm) axle capacity. 1500 Suburbans with the 6.5 L Turbo diesel used the 14 bolt axle from the 2500 series. Ground clearance was 6.9 inches, the approach angle was 18 degrees for the K-1500(28 degrees for the K-2500) and the break over angle was 18 degress.[23]

Transmissions included the 4L60 4-speed automatic in the 1500 series, and the heavier duty 4L80 4-speed automatic in the 2500 series. The manual transmission option from the previous generation was dropped.

The GMT400 series introduced independent front suspension. The 2WD models used coil springs and 4WD models used torsion bars in the front suspension. All models used a live axle and leaf springs in the rear.

0-60 mph time for a 1995 Suburban was 11.7 seconds.[23] City fuel economy was 13mpg[23] and highway was 15.[23] The turning circle was 47.8 ft.[23] In 1996, fuel economy had improved to 17mpg highway.[24]

Trim options included a base-level version, the LS, and the LT. Interior seating arrangements allowed for either bucket or bench seating in the first row, and optional 3rd row bench. The vehicle could be configured from 2- to 9-passenger seating.

Beginning in 1994, GM began making numerous annual changes to the Suburban, including:

In 1998, Holden introduced a right-hand-drive version of Suburban for the Australian and New Zealand markets with either petrol or diesel motors. A modified dashboard from 1995-2005 RHD Chevrolet Blazer was used. The models were withdrawn as a Holden brand because of low quality and sales.

The GMT800-based Suburbans were introduced in late 1999 for the 2000 model year. They were sold in two series: 1/2-ton 1500 and 3/4-ton 2500. Suburbans came in Base, LS and LT trims. Optional was pushbutton 4-wd with low-range transfer case). A tow hitch with trailer wiring plug was optional.

For 2000, Chevrolet's long-serving 5.7 L and 7.4 L V8 engines were retired along with the 6.5 L diesel. New were engines were 5.3 L (325 cu in) the 1500 series and 6.0 L (364 cu in) for the 2500 series.

New features included:

For 2001, the 6.0 L V8 in 2500-series Suburbans gained 20 hp (15 kW) from a number of changes including aluminum cylinder heads. A new 8.1 L (496 cu in) V8 was added as an option for the 2500 as well. OnStar became standard on LT models and LS models with the new Z71 package. Quadrasteer four-wheel steering was added as an option on 1500 series trucks.

2002 saw several optional features made standard equipment on the LS model, including front and rear air conditioning, alloy wheels, power windows, power front seats, side steps, fog lamps, and heated outside rear view mirrors. Base models were discontinued, leaving LS and LT.

The 5.3 L V8 in the 1500 series added flex-fuel capability. The 6.0 engine was not available in the 1500 series.

For 2003, all GM full-size trucks received an upgraded interior, with better-quality materials and other enhancements. New radios offered Radio Data System compatibility, XM satellite radio, Bose sound and improved ergonomics. Adjustable pedals were added as an option, and the instrument cluster-mounted Driver Information Center was improved and monitored up to 34 vehicle functions. A Panasonic DVD system was added as an option.

GM's Stabilitrak system was added, and Quadrasteer became available on 2500 series Suburbans. Towing capacity for Quadrasteer-equipped vehicles was reduced by 300 lbs (the weight of the system).[26]

For 2004, 1500-series Suburbans received the Hydroboost braking system that was previously introduced in the 2500 series.

The Mexican-market Suburban received a front end update this year, matching that of the Silverado.

The 2005 model year saw the long-standard side-hinged panel doors discontinued in favor of the formerly optional liftgate. All engines switched to an all-electric cooling system to reduce power loss and fuel consumption.

The Z71 package, long exclusive to 4wd models, became available on 2wd Suburbans. OnStar also became standard across the board.

Finally, Stabilitrak became standard on all models shortly after the start of the model year.

For 2006, the GMT800 Suburban's last year, a special LTZ trim package became available, featuring 20-inch (510 mm) wheels, all-wheel drive, and the LQ4 6.0 L engine of the 2500 series of trucks and SUVs.

The catalytic converters were relocated closer to the engine. The XM radio antenna and the OnStar antenna were combined into a single unit.

2010 GMC Yukon XL SLT
GMT900 GMC Yukon XL Denali

The 2007 model year Suburban and Yukon XL were unveiled at the 2006 Los Angeles Auto Show in January. Production of the redesigned GMT900 Suburban and Yukon XL began at Janesville Assembly and Silao Assembly in March 2006, with the vehicles arriving at dealerships in April.

The new models were redesigned with more modern, less boxy styling,[27] already seen on the previously released 2007 Tahoes and Yukons. The exterior features a more aerodynamic shape, made partly by a steeply raked windshield angle. The new design has less drag than previous models, making it more aerodynamic.

The interior has a redesigned dashboard and improved seats. It still retains its 9-passenger seating availability, which is available on LS models only. LT2, and LT3 models have leather seating and available 6-, 7-, and 8-passenger seating. There is a Z71 package available on LT2 and LT3 models which includes two-tone leather seats. All Mexican-built Suburbans including the 9-seat models offer the special two-tone leather seating used by the Z71. Chevrolet-Mexico offers a police variant of the Suburban with factory installed armor plate and an uprated Vortec 8100 RPO L18 and is arranged in the 9-seat configuration retaining the two tone leather trim of the Z71. This model is used by Mexican Police and is marketed as the LT-P (P for Policia) the Suburban LTZ comes standard with a DVD player,GPS navigation enhanced radio that is touch screen.

For the 2010 model year, in which U.S. News & World Report ranked it as the number one affordable large SUV,[28] the Suburban will add a new premium interior package that includes tri-zone climate control and handy features like Bluetooth and rear audio controls. In addition, radios that are standard in all 2010 trims get a USB port, allowing for music to be played from auxiliary devices though the radio, as well as charging other small electronics. The 6.0 liter engine in the 2010 models will also be flex fuel capable. Minor front end changes including a slightly raised front bumper and side torso air bags were also made standard for 2010.

In February 2010, Chevrolet unveiled a 75th anniversary edition of the Suburban, which will have the LTZ trim with white diamond tricoat exterior paint and cashmere interior, along with standard 20-inch chrome-clad wheels, revised roof rails, integrated navigation radio, XM Satellite Radio, Bluetooth phone connectivity, rearview camera, rear park assist, remote starting, adjustable pedals, and leather upholstery with heated/cooled front seats. Chevrolet says that the anniversary edition will be limited to 2,570 units because of the amount of white diamond paint GM can procure.[29]

The 5.3 L and 6.0 L engines carried over, and a new 403 horsepower (301 kW) 6.2 L Vortec V8 was added for the Yukon XL Denali.[citation needed] The 8.1 L engine was dropped.

For the 2011 model year, the Suburban will add three new exterior colors to the lineup: Mocha Steel Metallic, Green Steel Metallic, and Ice Blue Metallic. The trims will also get an updated modification, with the rear audio system, Bluetooth, floor console/storage area, wood grain interior, luggage rack rails, body-color exterior door handle/mirror caps and premium-cloth front bucket seats now standard on the 1LS trim, and chrome recovery hooks, two-speed transfer case, and 20-inch chrome wheels standard on its 1LZ 4WD models. In addition, the trailering package will feature the trailer brake controller as a standard on all trims.[30]

For the 2012 model year, trailer sway control and Hill Start Assist become standard on all trims, while the LTZ trim added a heated steering wheel and Side Blind Zone Alert as a standard.[31] Also, the LT1/2 options for the Suburban and SLE1/2 and SLT1/2 options on the Yukon XL were discontinued, leaving the Suburban with only a LS, LT and LTZ trim and the Yukon XL with a SLE and SLT trim. On March 30, 2012, GMC celebrated its 100th anniversary by releasing a special edition of its Yukon XL, offering a Heritage Edition trim package.[32] This would also be the final year that three colors, Graystone Metallic, Gold Mist Metallic and Blue Topaz Metallic, would be offered, along with the all season blackwall P265/65R18 tires.

For the 2013 model year, two new colors were offered: Champagne Silver Metallic and Blue Ray Metallic (extra charge). Also new is Powertrain Grade Braking, normal mode. The 2013 arrived for Chevrolet dealers in June 2012.[33]

For the 2014 model year, power-adjustable pedals, remote vehicle starter system and rear parking assist along with rear vision camera and inside mirror with camera display will become standard on the Suburban LS trims. In addition, Concord Metallic (which was supposed to be available for the 2013 MY) will be added to the Suburban color offerings for the 2014 models.[34] For the Yukon XL, an convenience package will now become standard on its SLE models, along with a new color, Deep Indigo Metallic.[35]

The three-quarter ton model's towing capacity is 9,600 lb (4,400 kg), being one of the best of any 4x4 SUV and matched only by the Toyota Sequoia's towing capacity. The three-quarter ton model also has a GCVW of 16,000 lb (7,300 kg).

The 2500 Suburban was originally sourced from Silao, Mexico from 2007-2008 but was moved to the Arlington, Texas assembly plant for the 2009 model year, where production of all GM fullsize SUVs was consolidated after the closing of the Janesville plant.[36][37]

GM discontinued the 2500 3/4 Ton versions of both Suburban and Yukon XL models after the 2013 model year.[38][39]

On September 10, 2013, GM announced that the twelfth generation Chevrolet Suburban and the GMC Yukon XL and Yukon Denali XL would be introduced to the public on September 12, 2013,[40] and unveiled the vehicles in different locations (The Suburban in New York, Yukon XL in Los Angeles) on that date.[41] Both vehicles are based on the GMT K2XX platform and will carry unique serial designated numbers, identified by platform (K2), brand (YC for Chevrolet, YG for GMC), drivetrain (C for 2WD; K for 4WD), tonnage (15 for half-ton, 25 for 3/4-ton, 35 for 1-ton), wheelbase (7 for short, 9 for long), and 06 for SUV, which means that a K2YC-K-15-9-06 would be identified as a Chevrolet Suburban 1500 4WD.[42] GM plans to put the Suburban and Yukon XL on sale in February 2014 as a 2015 model,[43][44] with the vehicles to be built exclusively in Arlington, Texas.[45]

Details and Features[edit]

The first reveals came on April 10, 2013 when Motor Trend posted the first spy shots of GM's large SUV lineup, using front covers that was borrowed from the Ford Expedition to throw the competition off.[46] Then on May 15, 2013, GM unveiled more new spy shots of the next generation Chevrolet Suburban/GM Yukon XL, which was expected to have the same frontal design as the Silverado but would have a more boxy style than the previous generations.[47]

On September 12, 2013, GM released the photos and press release of the newly redesigned Suburban and Yukon XL, and was later showcased to the public for the first time on September 27, 2013, at the State Fair of Texas.[48][49] This move by the way comes on the heels of the 80th anniversary of the first production of the Suburban in 1934.

On September 18, 2013, Chevrolet confirmed that there will be no three-quarter ton version or diesel variant of the full-size SUVs planned, but adds that the Z71 package will be available and its website will add updates on colors, pictures and prices before its sale date.[50] GM will also offer an off-road variant or trim for the Suburban and Yukon XL starting with the twelfth generation, which is in the planning stages.[51] One concept design for the Suburban called the Half-Pipe, whose features include roof racks and crossbars to mount skis, was featured at the SEMA Show on November 4, 2013; its parts will be available for order at Chevrolet Accessories.[52] This would later be followed by a video chat from GMC about the Yukon XL on November 6, 2013, which confirmed that the reason for the safety and fuel economy was the catalyst for GMC to no longer offer an AWD in the Yukon Denali XL and added that there will be no volume controls or devices in the rear seating area to operate the DVD system.[53]

The front fascias of the Chevy Suburban and GMC Yukon XL are distinct, but from the base of the A-pillars back, they share most of the same styling cues. This now includes inlaid doors that tuck into the door sills, instead of over them, which improves aerodynamics and fuel economy, and lessens interior noise. The hoods and liftgate panels now are made of aluminum in an effort to reduce vehicle weight, and the wiper blades that was located on the liftgate door is moved to the rear spoiler located on the top of the rear liftgate window. Also noticeable is the SUV's length, which expands from 222.4 in (5,649 mm) to 224.4 in (5,700 mm) and its width from 79.1 in (2,009 mm) to 80.5 in (2,045 mm), while the height decreases from 76.8 in (1,951 mm) to 74.4 in (1,890 mm), thus allowing the vehicle to become slightly leaner, a little bit wider, more streamlined, and more roomier than ever. A more-efficient, direct-injected EcoTec3 V8 powertrain (5.3 for the Suburban, 6.2 for Yukon XL/Yukon Denali XL) coupled with improved aerodynamics will now help offer greater estimated highway fuel economy for the SUVs, which GM hopes will improve its MPG and CAFE estimates, which will be announced before the vehicles go on sale.

Like the 2007-14 version, both the Suburban and Yukon XL do not share a single piece of sheetmetal or lighting element with the brands' full-size pick-up trucks, and the front grilles of both vehicles are slightly altered to give it their own identity. The front headlights will feature projector-beam headlamps that will flank the Chevrolet-signature dual-port grille – chrome on all models, sweeping into the front fenders, while the LTZ trims will feature high-intensity discharge headlamps and light-emitting diode daytime running lamps. The Yukon XL will also feature projector-beams on all trims as well. The improved safety features will include a 360-degree radar detection for crash avoidance and occupant protection and an anti-theft system that include vertical and interior sensors, in-glass and window breaking, a triggering alarm and a shutdown device that prevents the vehicle from moving.

Also new are the addition of fold-flat second and third-row seats (replacing the removable third seats), which is now a standard feature but can be equipped with an optional power-folding feature for the upgraded trims, and an additional two inches of leg room for second-row passengers. Multiple USB ports and power outlets are now spreaded throughout their interiors, including one 110-volt, three-prong outlet on both Suburban and Yukon XL, with the Suburban adding an available eight-inch color touch screen radio with next-generation MyLink connectivity along with an available rear-seat entertainment system with dual screens and Blu-ray DVD player, while the Yukon XL adds a standard eight-inch-diagonal color touch screen radio with enhanced IntelliLink and available navigation.

The Yukon XL interior will have more features that will include seats stuffed with dual-firmness foam, a standard Bose sound system and SD card slots, and laminated glass for the windshield and front windows, which decreases interior noise. The Denali Yukon XLs will come equipped with active noise-cancellation technology and come standard with GM's third-generation magnetic ride control suspension, which will be optional on the Suburban LTZ models, whose upgraded features will also include a real-time damping system that delivers more precise body motion control by "reading" the road every millisecond, and changing damping in just five milliseconds.

Reviews and Reception[edit]

The news of the redesigned Suburban and Yukon XL have so far been met with positive reviews from automotive critics who praised GM's devotion and commitment to keeping the Suburban and its sister SUVs in production due to their popularity and sales,[54][55][56][57] but at the same time have seen mixed comments from message boards like Autoblog and Chevrolet's Facebook page, mainly about the front grille, its boxy design, and the lack of additional features not included in the Suburban, like a Duramax engine. In a review from Automobile Magazine, writer Greg Migliore notes that despite the reception from both sides and the possibility that other automakers might exit the large SUV segment, that with this 12th generation, "GM is clearly hoping the Suburban makes it to the century mark." [58]

Safety[edit]

For the 2009 model year, the Suburban received the U.S. National Highway Traffic Safety Administration's (NHTSA) best rating of 5 stars in the frontal driver/passenger and side driver/passenger categories.
