The front of the engine is so close to the firewall that mechanics some years from now having to change the accessory belts or timing chain will be cursing the design engineers because they left no room to pull out the old belts or install the new ones.
The car will have to be hoisted so the mechanic can crawl underneath. Then the engine (in front of the rear axle) and the differential and 8-speed dual-clutch transmission (extending behind the rear axle) will have to be unbolted as a unit and lowered from the chassis far enough for mechanics to access the belts, GM engineers confirm.
