UPDATE: Shanghai GM has issued an official press release on the ATS-L, which we've included below, and which mentions only the turbo four as the sole engine on offer. The text has been updated accordingly.
Cadillac Ats L
To luxury automakers, long-wheelbase sedans are to China that crossovers and SUVs are to the US, so it isn't all that surprising any more when the latest sedan gets an extra couple of inches between the wheels to improve rear-seat comfort. According to Car News China, the next sedan to get the stretch will be the Cadillac ATS, which will increase the wheelbase by 10 centimeters (about four inches) to become the ATS-L.
