Chronology
Successor	Mercedes Benz V-Class

The Mercedes-Benz R-Class is a mid-size luxury MPV introduced by Mercedes-Benz in 2005 for the 2006 model year. Following the success of the smaller A- and B-Class MPVs, Mercedes in collaboration with coachbuilder Stola presented a concept vehicle, Vision GST (Grand Sports Tourer), at the 2002 Detroit Auto Show^[5] and a second one, Vision R presented at the 2004 Detroit Auto Show,^[6] subsequently introducing the production version at 2005 New York International Auto Show. The R-Class was manufactured in Vance, Alabama until 2015 when its production was shifted to Mishawaka, Indiana for a smaller volume production until 2017.

The R-Class (W251) shared its platform with the M-Class (W164) and GL-Class (X164) and was available in two wheelbase lengths: standard 2,980 mm (117.3 in) and long 3,215 mm (126.6 in). The R-Class was sold in the United States and Canada in long wheelbase only. The R-Class in both standard and long wheelbases were sold internationally until the end of 2013 with exception of China where R 320 and R 400 with long wheelbase continued to be sold until 2017.

Mercedes-Benz announced in May 2007 that the R-Class model range would be expanded with more engine options and availability of rear-wheel-drive system for selected models in addition to 4MATIC all-wheel-drive system. A new smaller 3.0-litre V6 was available in both petrol and diesel versions. The seating options became more flexible, offering five, six, or seven seats. AMG styling option was added to the extensive list of standard and extra-cost options.^[7]

The R-Class received a major update with facelift to the front and rear fascias, grille, side mirrors, and taillights for the model year 2011. The revised model was unveiled at the 2010 New York International Auto Show.^[8][9]

At the same time, the new 5.5-litre V8 motor was introduced to R-Class for the first time since the last R-Class with V8 motors, R 500 and R 63 AMG, were withdrawn from the market in 2007.^[10] The reintroduced R 500 was not offered in the North American market. The North American market continued with R 350 4MATIC and R 350 BlueTEC 4MATIC, both in long wheelbase form and with V6 engines only, for 2011 and 2012.

The AMG version of the W251, R 63 AMG 4MATIC, was introduced at the 2006 North American International Auto Show as a 2007 model. It featured a handbuilt 6.2-litre M156 E 63 V8 engine producing 375 kW (510 PS; 503 bhp) and 630 N⋅m (465 lb⋅ft) of torque. The R 63 AMG was equipped with same engine, seven-speed AMG Speedshift 7G-TRONIC, and 4MATIC all-wheel-drive system from ML 63 AMG and GL 63 AMG.^[11] The driver can manually select the gears by pressing the upshift and downshift buttons placed behind the steering wheel spokes if desired. No rear-wheel-drive option was offered in R 63 AMG 4MATIC. The top speed is electronically restricted to 250 km/h (155 mph) or 275 km/h (171 mph) with optional extra-charge AMG Driver's Package. Despite its heavy weight, the acceleration was brisk with 0–100 km/h (0–62 mph) time of 4.6 seconds.

A high performance version of R-Class wasn't well-received due to its poor handling dynamics, especially with the heavy V8 engine.^[12] With 200 units built for the worldwide sale, this model was the rarest of R-Class and amongst the rarest AMG models.^[13] Due to extremely low sales and the lack of advertisement, R 63 AMG was withdrawn from the market in 2007, making it a single model year.^[14]

From 2014 to 2017, the long wheelbase R-Class was sold in China only with one engine option in two different power outputs: R 320 4MATIC and R 400 4MATIC.^[15] The R-Class enjoyed a steady popularity in China with annual sales between 12,000 and 14,000 units per year.^[16] Due to its small sales volume, the production was shifted from Alabama to Indiana where the R-Class for Chinese market was assembled by contract manufacturer AM General from 2015 to 2017.^{[17][3][4][18]}

• R 500 was sold with 5.5L in the U.S., Canada as the R 550.

All models except for R 350 4MATIC BlueEFFICIENCY, R 400 4MATIC, R 300 CDI BlueEfficiency, and R 350 BlueTEC 4MATIC use seven-speed 7G-TRONIC automatic transmissions. The latter four models use seven-speed 7G-TRONIC plus automatic transmission.

The R-Class scored "Good" in the Insurance Institute for Highway Safety (IIHS) front crash test but "Acceptable" in the side impact crash test due to the excessive load against the dummy's torso.^[19][20] After modifying the seatbelts and interior door trim for the 2009 model year, the IIHS rated the R-class "Good" overall in side impacts allowing the R-Class to receive the Top Safety Pick award.^[21]

In the United Kingdom, Thatcham Research's New Car Whiplash Ratings (NCWR) tested the R-Class and awarded it the top "Good" rating overall for its ability to protect occupants against whiplash injuries.^[22] Thatcham Research's New Vehicle Security Ratings (NVSR) awarded R-Class with five out of five stars for vehicular theft deterrent and four out of five stars for breaking-in deterrent.^[23]

Mercedes targeted 50,000 sales per year, half of those for the North American market. While the initial strong sales of first two model years, 2006 and 2007, the sales fell in 2008 following the recession, reaching less than ten percent of ML-Class sales.^[24][25] Sales continued downward, and R-Class was discontinued in 2012 for the North American market and in 2013 for Europe and other markets — with exception of China where R-Class enjoyed popularity. Mercedes-Benz Metris introduced in 2014 is considered a successor to the R-Class for the North American market.

In Germany, the limited engine choices and lack of available rear-wheel-drive option at the launch led to slow sales with almost 4,500 units sold in 2006. The sales decline followed for a few years despite adding more engine choices and rear-wheel-drive option. The 2011 mid-cycle refresh increased the sales to almost 2,500 before dropping to less than 500 units for the final model year, 2013.^{[citation needed]}

The cause of its poor sales performance is hard to attribute, considering a multitude of possible reasons. One is the confusing marketing of what the R-Class is: Mercedes-Benz tried to persuade customers that the R-Class represented a new category of luxury passenger vehicle with the attribution of station wagon/estate, crossover, SUV, and van rolled into one.^[28] Additionally, Mercedes-Benz initially marketed the R-Class as a "Sports Cruiser" and later as a "Family Tourer".^[29] It also suffered from the "image problem" caused by the ill-fated Chrysler Pacifica that looked too similar to the R-Class and was similarly sized despite the R-Class having more luxury features and a better managed launch. The Chrysler Division of its parent company, DaimlerChrysler, had introduced the Pacifica two years prior to the R-Class, and the Pacifica was plagued with production and quality issues as well as poor marketing and few engine choices. Secondly, the customer preference had shifted away from MPV minivans and vans to CUV's and SUV's during the late 2000s and most of the 2010s. Thirdly, the Great Recession of 2008-2009 greatly impacted automotive sales and consumer confidence along with a strong increase in fuel prices, making the R-Class less desirable due to its higher fuel consumption.

The mid-cycle refresh didn't help with sales at all despite an updated fascia appearance more in line with the M-Class and GL-Class and a better interior.
