For 2009, the basics of the G37 coupe stay the same with two major upgrades coming down the pipe. For the first time since the G-coupe rolled off the assembly line it will be offered with Infiniti’s intelligent ATESSA E-TSÔ (Advanced Total Traction Engineering System for All Electronic Torque Split) all-wheel drive system. ATESSA E-TSÔ uses an advanced torque split control strategy which transfers optimum torque to the wheels according to road and driving conditions resulting in outstanding handling due to optimum torque distributionfrom front to rear (50:50 up to 0:100). It also provides high starting traction performance and smooth and stable acceleration with a 50:50 torque split when launching from standing start. Additionally, the automatic 5-speed transmission is upgraded to a new 7-speed unit. The new 7AT should allow for quicker performance and reaction times while also having the capability of slightly increasing estimated miles per gallon.
The sedan steps up in 2009, to the same VQ37VHR motor as the G37 coupe. Receiving a name change, the new G37 sedan will step up to 328hp and will receive the same 7-speed automatic transmission offered in the G37 coupe. Furthermore, the sedan will be available with sport brakes using 4-piston front/2-piston rear calipers and large 14-inch front and 13.8-inch rear rotors. To top off the upgrades,a new sport 18-inch wheel design will be offered along with Infiniti’s Scratch Shield paint which uses a new technology in which a scratch-resistant resin is applied to the paint in order to allow it to “self heal”. Dependent on the depth and the outside temperature, scratches may repair themselves within a week’s timeframe.
