Mercedes will launch an updated and more powerful version of the G-Class SUV in India on February 22. The new G-class will be called the G63 AMG and it will replace the G55 AMG. The G-Wagen’s design has largely remained unchanged through its 33 year lifespan. Although the design hasn’t evolved much, the G-Class is loaded with technology. The updated G63 made its public debut at the Bejing Auto Show earlier. The reworked G-class gets a series of subtle exterior styling tweaks, a new engine mated to an updated gearbox, a lightly altered interior and a brace of new electronic driver aids. The G63 AMG is visually distinguished from their standard siblings by a two-slat grille, a deeper front bumper with larger air ducts, red brake callipers and unique 20-inch wheels. As with the outgoing G55 AMG, the G63 AMG also receives side mounted exhaust pipes that exit from underneath the rear doors on either side. Power comes from a 544bhp version of AMG’s contemporary twin-turbocharged 5.5-litre V8 engine which is mated to a seven-speed 7G-tronic gearbox. The G63 AMG benefits exclusively from stop-start along with brake energy recuperation systems that contributes to better fuel economy. Drive is channelled permanently to all four wheels with a trio of differential locks providing added traction in the rough. Other upgrades brought to the G-class is a revised instrument pack brought over from the third-gen M-class together with a colour monitor and Merc’s latest Comand system. Additional features include Mercedes-Benz’s hi-tech Distronic Plus radar controlled cruise control system, Blind Spot Assist and the parking aid Partktronic, which now incorporates a reversing camera. The standard ESP (electronic stability program) has also been revised and now includes Trailer Stability Assist and a hill hold function. All G-class models are assembled by Mercedes-Benz partner Magna Styr.
