It’s been a busy 48 hours, with dozens of new cars and concepts revealed at the 2014 Detroit Auto Show. One of the highlights was the 2015 Acura TLX Prototype. The car is a preview of Acura’s new mid-size sedan due out later this year, which will replace both the aging TSX and TL in the Japanese automaker’s lineup.

One of the real stars, meanwhile, was the 2015 Subaru WRX STI. Subaru didn’t pull any surprises with the car, with the latest model once again packing a turbocharged four-cylinder boxer engine and symmetrical all-wheel-drive system.

One of General Motors’ top engineers has revealed that the Alpha rear-wheel-drive platform would be a good fit for any successor to the Chevrolet SS, should such a car be approved for production. The best part is that going with the Alpha platform will mean a lighter and more dynamic version of the car.

You'll find all of this and more in today's car news headlines from around the High Gear Media network, right here at Motor Authority.
