Like it's CL63 AMG stablemate, the S63 sedan gets a new biturbo engine for the 2011 model year. A few other nice touches promise to make this supersedan even better than the last.

Audi tuner MTM has announced its first modifications for the new RS5, and now that Audi itself has confirmed the car will come to the US, this is actually relevant news for us.

It's what's on the inside that counts. Despite being touted as not the best-looking car on the market, Porsche's Panamera is flying off the lots, with 25,000 having been built in the car's short life.

No surprise here. After the overwhelmingly positive response to the 918 Spyder Concept revealed earlier this year in Geneva, Porsche has committed to developing the sports car for production.

We'll have photos and a live report from the debut tomorrow morning, but for now check out these initial pictures and learn what we know thus far.

If you thought Porsche, a strong supporter of the Save the Manuals lifestyle, would be the last to let go of the romanticism of the internal combustion engine, sorry. The 911 GT3R Hybrid race car was just the tip of the iceberg.
