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

GM looks to combat high theft rates on SUVs with added tech

The Cadillac Escalade has been at or near the top of most-stolen and insurance-loss lists for more than seven years, until it dropped to number six earlier this year. In 2011 it was fitted with a host of new security features to address its easy-to-override features and that has brought the number of thefts down, but when eight of the ten most stolen rides are large SUVs from General Motors, no one will argue that something else needs to be done.
Thus, GM has fitted this same theft-deterring tech to the 2015 Suburban, Tahoe and Yukon. The Suburban and Tahoe will get the steering lock that the Escalade and Yukon already get, plus bolted-down third-row seats to deter thefts like this, stronger door lock cylinders and shields, and side-cut keys to inhibit picking.
Additional security measures in a Theft Protection Package can be purchased for $395, consisting of sensors on the greenhouse glass and interior, an incline/tilt sensor and added "key control systems" to make it more difficult for the men in black balaclavas to steal what you bought.

GM patent reveals new two-stage turbocharger

Modern turbochargers may be some of the best ever made, but performance is something that engineers are always trying to improve. According to GM Inside News, General Motors (GM) is hoping to alleviate some of the negative aspects of a two-stage turbocharger setup with a newly-patented design. The patent, that was filed on May 19, 2016, reveals a clever bypass system that allows the engine, a four-cylinder unit, to optimize both the low-pressure and high-pressure inlets for its respective functions. According to the filing, a conventional two-stage turbocharger setup is engineered to allow both turbines to operate simultaneously at low and mid engine speeds. At high engine speeds, only the low-pressure turbine works. The setup can't isolate either the low or high pressure side, which can impair low-end performance. GM's new two-stage turbocharger setup looks to eliminate this by linking the high-pressure turbo to the exhaust manifold through the high-pressure inlet duct. The low-pressure turbo is attached to the high-pressure turbo by a low-pressure inlet duct, which is linked to a connecting channel. A single actuator that is housed in the exhaust manifold creates a bypass that can opens the high-pressure inlet or close the connecting channel. Depending on what the engine load and speed is, the ECU guides the actuator—a single rotating spindle with discs corresponding to flanges on the high and low pressure sides—to isolate one of the two turbos. Isolating the turbos allow the respective inlets to be engineered for the best possible fluid dynamic performance. The setup should increase performance and decrease lag. There's no word on what car this setup will make an appearance on, but it will most likely be used in premium vehicles before trickling down to the rest of GM's vehicles.
