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

Gas Prices Could Bring Economic Recovery

Just when it looked like people were more willing to spend money again on non-essential items—and on more essential (but deferrable) purchases like new cars—rising prices at the pump could grind some aspects of economic recovery to a halt.

After a major price spike in summer 2008, when prices topped $4 a gallon on a national average, gasoline prices plummeted at the end of 2008 to well under $2 then after a quick rise to about $2.50 have risen only gradually until about a month ago. Prices have risen about 40 cents a gallon over the past month.

Although prices this time aren't expected to spike with the volatility they did in 2008, many analysts haven't ruled out $4 gas this year—especially after political events in the Middle East and North Africa.

The Rinspeed BamBoo enjoys the summer sun

Rinspeed has unleashed a mammoth collection of photos featuring its upcoming BamBoo. We eagerly await spying this grown-up golf-cart (their words) in person at the 2011 Geneva Motor Show. The photos are heavy on the stylized portrayal of wealthy youth enjoying a summer in Saint-Tropez, yet they reveal little of what's under the BamBoo's skin.

We do know that its German-made 54-kW electric motor will allow speeds of up to 75 miles per hour and that its battery (unknown chemistry) offers 65 miles of range. What's more, it appears that there may be a bicycle or two taking up residence in the rear cargo area. Tech junkies will surely appreciate the included seven-inch (Android-powered?) tablet computer.
