Audi R8 GT Spyder

Destined to be previewed at Le Mans in June before its proper unveiling at the Frankfurt Motor Show in September, the R8 GT Spyder has been teased with these preview sketches released to the British motor press.Expect the same 560-horsepower V10 as the coupe, mated to Audi's R-tronic six-speed automated manual transmission. But with the droptop's interrupted aerodynamics and added weight, the R8 GT Spyder expected to top out at 193 mph – six mph shy of the coupe's top end. The rear spoiler, front splitter, upgraded brakes and weight reduction regime (less sound isolation, thinner glass and carbon-fiber components) should carry over, as should the Alcantara interior.Production is expected to be capped around the same as the coupe's 333 units worldwide, likely with a slightly higher price tag.

Audi A3 e-tron

Based on Audi's entry-level hatchback, the A3 e-tron packs an electric motor under the hood which sends power from the rear- and mid-mounted battery packs to the front wheels. Output is rated at 100 kW (just over 130 horsepower) and 199 pound-feet of torque, with the 26.5 kWh lithium-ion batteries providing a range of around 90 miles. The electric A3's performance figures to be far from enthralling, requiring 11 seconds to hit 60 mph and topping out at just 90 mph, but with a 400-volt rapid charger, getting juiced up can take as little as four hours – or as long as nine with a standard 110-volt outlet.Other modifications include a new gauge cluster, a low consumption HVAC system and a heated windshield, but when the A3 e-tron is set to hit the market is still up in the air. The R8-based flaghip will supposedly go on sale sometime in 2013, but if Audi wants to get in on the EV action sooner
