Get the full details of the new 4.2 liter engine now available on the Audi R8 Spyder. The story inside.

Potential new customers of the Audi R8 Spyder will have an additional engine choice to consider before placing an order.  The German automaker will make the car available with a 4.2-liter FSI V8 engine that produces 430 hp (316 kW) and up to 430 Nm (317 ft-lb) of torque.

Up until now, the car had only been offered with a 5.2-liter FSI V10 that kicks out 525 hp (386 kW) and up to 530 Nm (391 ft-lb) of torque, as seen in the pictures here.  Photos of the car with the new engine have not yet been released.

With the new engine, and the R-tronic sequential manual transmission, the car sprints to 100 km/h in 4.8 seconds, before hitting its 299 km/h (186 mph) top speed.  Quattro all-wheel drive is also included.  Fuel consumption with the R-tronic is a 13.9 liters per 100 km, or 17 mpg.  With the six-speed manual, that figure jumps to 14.9 liters, or 15.79 mpg.  Energy recovered during braking was installed to help improve fuel economy on the R8.

The engine features a crankcase made from an aluminum and silicon alloy, and uses forged aluminum pistons with steel connecting rods.  It has a separate oil tank and a dry sump lubrication system.  Weight for the engine is listed at 216 kg (476 lbs.).

Normal options are still available on the car, including leather upholstery, carbon fiber interior fittings, piano black trim, Alcantara headliner, and more.   The Audi R8 Spyder 4.2 FSI quattro will hit the German market for €121,000, beginning in the third quarter of 2010.
