Mercedes-Benz GLE

The Mercedes-Benz GLE, formerly Mercedes-Benz M-Class (designated with the "ML" nomenclature), is a mid-size luxury SUV produced by the German manufacturer Mercedes-Benz since 1997. In terms of size, it is slotted in between the smaller GLC and the larger GLS, the latter with which it shares platforms.

The first-generation M-Class, designated with the model code W163, is a body-on-frame SUV and was produced until 2004. The second-generation M-Class (W164) moved to a unibody platform while sharing most components with the GL-Class, which sports a longer body to accommodate third-row seating.

For a short time, between 1999 and 2002, the W163 M-Class was also built by Magna Steyr in Graz, Austria, for the European market, and the W166 M-Class from 2011 to 2015 was built in Stuttgart for the European and Australian market, before all production moved to the U.S. plant near Vance, Alabama in 2015 with the release of the facelifted W166 model, in an effort to harmonize Mercedes-Benz SUV nameplates by aligning it with the E-Class.

Nomenclature update from M to GLE

Although grouped under the "M-Class" naming banner since the first launch, BMW, who sells M models such as the M3, objected to the car being badged "M" with the three-digit engine level afterwards (e.g. M 320). This forced Mercedes-Benz to defer to a double-tiered marketing strategy of "ML" badging (e.g. ML 320) under an M-Class umbrella.[1] There has been some confusion surrounding this nomenclature, with many sources erroneously referring to the series as the "ML-Class",[2][3] including Mercedes-Benz itself.[4][5]

From 2015, with the release of the facelifted W166 third-generation model at the New York Auto Show in April, the M-Class was renamed to GLE as per the revised nomenclature adopted by the brand. Under this scheme, SUVs use the base name "GL", followed by the model's placement in Mercedes-Benz hierarchy. The "G" is for Geländewagen (German for off land wagon or off-road vehicle) and alludes the long-running G-Wagen. This is followed by the letter "L" that acts as a linkage with the letter "E"—the GLE being the SUV equivalent to the E-Class.[6][7]

First generation (W163; 1997)

Second generation (W164; 2005)

In 1999, development on a successor to the W163 began under the codename "W164" and spanned a period of six years. First design drafts appeared in 2000 with the first models in scale 1:4, and in 2001 three full-sized models were prepared.[23] In 2002 the design styled by Steve Mattin under Peter Pfeiffer was chosen and approved by the executive board.[24] Design patents were filed in Germany on 10 June 2003 and in the U.S. on 25 July. Prototype testing was conducted throughout 2003 and 2004, concluding in early 2005. The redesigned M-class (chassis name W164) was introduced in April 2005 as a 2006 model after a showing at the North American International Auto Show in January. It was almost entirely new, with a more sporting, aerodynamic look. The coefficient of drag was reduced to 0.34. Mercedes-Benz made the new M-Class 71 mm larger, 150 mm longer and 5 mm lower than the first model. The M-Class was named "Best New Sport Utility Vehicle" in the 2006 Canadian Car of the Year awards.

Mercedes-Benz extensively publicised the US$600 million spent to update its factory and add manufacturing space for the new R-Class. According to early automotive press reports, the 2006 M-Class vehicles demonstrated vast improvements in quality.

Third generation (W166/C292; 2011)

In 2006, development began on the next-generation M-Class and spanned over a period of 5 years, a shorter duration than its predecessor. In 2008, the final design by Emiel Burki was approved and patented domestically on 16 December 2008 (U.S. design patent filed on 15 June 2009). The newly redesigned M-Class (chassis name W166) was introduced in pre-production form 10 June 2011 as a 2012 model. The first customer-designated W166 rolled off the Vance production line on 20 July.[32] It is moderately refined, taking styling cues from the new generation Mercedes-Benz E-Class. An increase in rear seat legroom has been implemented, alongside adjustable rear backrests. It was to be launched in September 2011.

New features in the 2012 M-Class include an updated 7G-Tronic Plus seven-speed automatic transmission to provide improved fuel economy, optional adaptive cruise control (Distronic Plus), active lane departure warning system, and an adjustable-height air suspension (AirMatic). An active curve system with active anti-roll bars for body roll compensation was introduced.[33]

The W166 was one of the last vestiges of the joint venture between Daimler and Chrysler while they were a consolidated company. DaimlerChrysler developed the core platform and technology, benefitting from Chrysler's strong SUV sales and R&D domestically.

Fourth generation (W167/C167; 2018)

The fourth generation GLE was unveiled at the 2018 Paris Motor Show.

At launch, the GLE was sold in the U.S. with two engine options. The GLE 350 has a 2.0-liter 4-cylinder engine with 255 hp and the GLE 450 has a 3.0-liter, inline-6, turbocharged engine with 362 hp and 369 lbft of torque. The GLE 450 has a 48V electric system with an integrated starter motor. The system powers the air-conditioner, in-car electronics and the electronically driven turbocharger.[56] The GLE 450 features a refined Active Body Control system, that does away with mechanical roll bars, notably enhancing performance.[56]

Other engine options are also available. The AMG GLE 53 was introduced at the 2019 Geneva Motor Show in March. It has a 3.0 L turbocharged I6 producing 429 hp and 384 lbft of torque. A 48V electric system like in the GLE 450 features EQ Boost for an extra 21 hp and 184 lbft torque on demand.[57]

For the first time under the "GLE" name, the GLE also adds a seven-seat option.
