Watch President Obama drive a Corvette around the White House

The season seven premiere of Jerry Seinfeld's web series Comedians in Cars Getting Coffee went live tonight on Crackle featuring the show's biggest guest so far. Yes, that's President Barack Obama driving a car around his front lawn. Seinfeld brings a classic Vette – a '63 split-window coupe with a 327 V8 and a stick!– to 1600 Pennsylvania Avenue for the president to ride in and later drive in a circle. Though they don't leave the White House grounds and barely break a walking pace, Obama seems to enjoy the rare event. For the caffeinated portion of the episode, the president and Seinfeld sit down in the White House's staff dining room. They chat about the usual stuff – celebrity status, the seat warmers in The Beast, their daily routines, and cursing. The video meant to be presented here is no longer available. Sorry for the inconvenience. From Crackle: Just Tell Him You're the President This is likely one of few times during Obama's two terms in office that he will get behind the wheel of a car. His VP Biden is no doubt jealous, as he owns a '67 Corvette 327 that the Secret Service won't let him drive. And yes, we realize Obama is not a comedian. There's probably a joke there, but we are not going to make it. Humor Chevrolet Videos jerry seinfeld comedians in cars getting coffee

The engine, which uses a computer to control the blend proportions, is about 15 percent more efficient than the any diesel engine according to mechanical engineering professor Rolf Reitz. The team has put the experimental reactivity controlled compression ignition (RCCI) engine in a demonstration car - a 2009 Saturn. "This vehicle can do 50 miles per gallon," says Reitz, who believes the system could be improved further. Read more at Wisconsin Public Radio.

Chevy updates Silverado HD with new towing equipment

Enamored by the updated Chevy Silverado released just the other day, but need something a little more heavy duty? Chevy isn't going to keep you around waiting for long, as it has now revealed a new Silverado HD as well. While the new Silverado 1500-series has been distinguished over the outgoing version principally by its revised styling, the updated Silverado HD is more about its enhanced equipment. It's got a new Digital Steering Assist system (on some models) designed to enable easier and safer towing. There's a new gooseneck/5th-wheel trailer prep package that enables Chevy's new heavy duty truck to tow as much as 23,200 pounds. And the interior equipment is augmented as well by a new MyLink system with seven- or available eight-inch display, Apple CarPlay and Android Auto capability, wireless phone charging and more. Buyers will be able to choose between two versions (2500HD and 3500HD), four trim levels, three cab sizes, two cargo box lengths, and numerous powertrain and drivetrain configurations for a staggering array of combinations. There'll also be several special editions and packages, like the Z71 for off-road use and Custom Sport Edition for a sleeker look, as well as chassis cab and CNG versions. Scope out the full details in the press release below and the fresh batch of images in the gallery above.
