Another prototype for Audi’s second-generation R8 Spyder has been spotted. Like the coupe, the new convertible supercar will be available exclusively with a V-10 at launch but a smaller, turbocharged engine is expected to be offered at some point.

Speaking of engines, Fiat Chrysler Automobiles [NYSE:FCAU] has updated its range of Pentastar V-6 engines. The new engines are being introduced for the 2016 model year and offer improved efficiency and torque.

There are only nine Lamborghini Veneno Roadsters in the world and one has just been spotted on Rodeo Drive. The car is still as striking as the day the original Veneno coupe made its debut at the 2013 Geneva Motor Show, and we can’t imagine that ever changing.
