Mercedes C63 AMG (2007): first official pictures

By Jack Carfrae First Official Pictures 04 July 2007 12:54 Mercedes C63 AMG: the lowdown Mercedes has a penchant for extremely powerful saloons and sports cars, in case you hadn't noticed. We've been inundated with the likes of the CL65 AMG, the CLK Black AMG and the McMerc SLR Roadster. Not content with these tyre-shredding giants, Mercedes has now shown the C63 AMG just 48 hours before the launch of the BMW M3.

The 500-hp club

Petrol heads, continue to rejoice: Car manufacturers have not ignored your cries for high-powered cars and trucks. Despite tightening emissions regulations and rising fuel costs, automakers are building an increasing number of vehicles putting out at least 500 horses. Based on our research, there are over 80 cars sold in the United States that deliver these burnout-inducing numbers (not including tuners such as Mosler or Callaway).

2014 Porsche Cayman gets a performance-testing iPhone app

To promote the new 2014 Cayman, Porsche has cooked up an iPhone app called “Cayman Code of the Curve.” You're probably already rolling your eyes at the prospect of another automaker app that is little more than a downloadable advertisement, but this seems to be something different -- the app is designed to record your driving performance in real-time and then share results with friends. Porsche enthusiast site flatsixes.com has an exclusive first look at the app, which is still in development but is reported to be coming “soon.” Based on preliminary screenshots provided by Porsche, the app instructs users to set up a variety of courses -- cone slalom, autocross and reaction-time challenge courses are shown -- then uses the iPhone's internal accelerometer and GPS receiver to track and record your performance. You'll also be able to use the app's “record your curve” function to share favorite drives with friends on Facebook.
