The next-generation Infiniti G sedan and coupe will be based on a stretched version of the upcoming Mercedes-Benz C-Class platform. A two-inch wheelbase increase is being engineered to allow for similar rear-seat interior space to the current G model.
Infiniti is rumored to be preparing an twin-turbo 3.7-liter V6 for a IPL sports model, which is intended to compete with the M-Series BMW 3 models. The good news is that the direct-injected turborcharged powerplan is to produce approximately 530 horsepower); and a steep pricetag.
The Infiniti insider that spoke to Motor Trend also stated that the G series will gain a hybrid model with a powertrain similar to that of the Infiniti M Hybrid Sedan. An updated version of well-regarded Nissan’s VQ-series V6 - and a Mercedes-Benz turbodiesel 2.1 liter four-cylinder engine - will likely also be offered, but the turbo-diesel is probably not destined for sale in the U.S. - unfortunately.
Renault-Nissan Group and Mercedes-Benz parent Daimler announced an alliance focused on powertrains and platforms back in 2010, and the C-Class based new G-series is one of the first Infiniti vehicles to benefit from this alliance.
