According to a recent report, Cadillac is developing an electric all-wheel-drive system for the next-generation of V-Series models.
Details are limited but the system would presumably use an electric motor to power the front wheels of rear-wheel drive models such as the ATS-V and CTS-V.
Little else is known about the system but Cadillac President Johan de Nysschen told Edmunds it wouldn't be added to existing models because platforms need to be designed to accommodate the system from the beginning. This likely means it will be several years before we see a high-performance Cadillac with all-wheel drive.
In related news, speculation suggests the system could eventually be offered on other rear-wheel drive models including the Chevrolet Camaro and Corvette.
