When a 2015 Ford F-150 prototype was spotted leaving GM’s Milford Proving Grounds in 2013, automotive pundits assumed it was part of the joint venture to develop the RWD 10-speed automatic transmission that will be used in the upcoming Ford Raptor and Camaro ZL1. Well, they were partly right.
The all-wheel-drive system is the same unit found in the Cadillac ATS and is produced by American Axle (AAM). The same suspension mounting points are shared between the ATS and the Camaro, making the packaging relatively easy. Naturally, the Rally Sport will be powered by a 2.0L, turbocharged, four-cylinder engine, with the 275hp LTG coming as the only hardware option.
The LT1 V8 simply takes too much space under the hood and the lighter four-cylinder helped with both packaging the front axle and balancing the additional weight. However, performance can be boosted by way of a Chevrolet Performance Stage 2 kit, soon to be added to the catalog. A larger charge cooler, downpipe, and high-flow exhaust, along with a tune, increase power to 320 hp and 300 lb-ft of torque.
