Speaking with Car and Driver, Cadillac marketing chief Uwe Ellinghaus confirmed that such a project is in the works. But unlike its rivals, Cadillac aims to go with a rear-wheel-drive layout. This despite research that apparently indicates that a surprising 80 percent of owners think that their BMW 1 Series is front-drive. It's the driving dynamics and styling proportions that motivate Ellinghaus and his colleagues to stick with rear-drive, however.
The new model would in all likelihood be based on the same GM Alpha architecture that underpins the ATS and CTS – a platform that has helped Cadillac keep the weight down on both models and which is expected to underpin the next-generation Chevy Camaro, as well. The sub-ATS could be positioned as a four-door 2+2, however, as the ATS grows a little larger in its next iteration in order to make room for its new baby brother.
Expect four-cylinder engines – including the 2.0-liter turbo four and a replacement for the base 2.5-liter naturally aspirated four found in the ATS – to provide the motivation, but it may be another few years before the new compact model arrives as part of an expanded Caddy family to launch upwards as well with a new flagship sedan. Just what Cadillac would call it, however, remains a mystery, as the ATS obviously starts the nomenclature succession at the start of the alphabet.
