Cadillac’s all-new CTS-V has been revealed and we’re glad to report that rumors of a 640-horsepower rating have proven true. Yes, the third-generation CTS-V is now more powerful than all of its rivals, and it even manages to outgun supercars like the Ferrari 458 Speciale and Lamborghini Huracán.

Audi is set to build 75 special edition RS 5 coupes and they’re all earmarked for sale in the U.S. No extra power is on offer but the cars do get a few enhancements from the Audi Individual personalization department.

Napoli-based startup Puritalia has finally revealed its 427 roadster in production trim. Just 427 examples will be built after which a new grand tourer equipped with a hybrid powertrain will follow.

You’ll find all of this and more in today’s car news right here at Motor Authority.
