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.

2013 North American Car and Truck/Utility of the Year finalists announced [w/poll]

2012 is almost in the books and automakers are spending December gearing up for the 2013 auto show season, which tips off next month at the Detroit Auto Show. Traditionally, the latter opens up with the announcement of the North American Car and Truck/Utility of the Year awards, and this year figures to be no different.
But up until this moment, we didn't know which six vehicles would be parked ahead of the stage as finalists, with executives and engineers waiting for the winners to be disclosed. Whittled down from October's "short list" of nominees (11 cars and 10 truck/utility vehicles), the finalists are as follows:

Liberace's gilded Cadillac could be yours

With their chrome grilles and oversized wheels, it's hard not to notice a Cadillac these days. But this one is even more blingtastic on account of the 23.75-karat gold-leaf bodywork.
The 1931 Cadillac Golfer's Drop Head Coupé is said to have belonged to the inimitable performer Liberace, who didn't just have it covered in gold - he also had the exterior door handles plated in silver and the inside handles in 24-karat gold as well. It's also got a white leather interior and headlights that - well ahead of their time (if you'll pardon us, Mr. Tucker) - pivot with the steering wheel. All that bling is powered by a 5.7-liter V8 mated to a three-speed automatic transmission that pales in comparison to the seven, eight and even nine-speed gearboxes appearing on luxury sedans today.
The project was undertaken over the course of three years in the 1970s by one Jack Smith from Kansas. Smith (if that was his real name) sold it at auction in 1975, and it was most recently displayed for 12 years at a museum in Germany which claimed it was Liberace's own. The car is now going up for sale by Barons' at the Sandown Park horse racing track in Surrey, England, on September 17, when bidding starts at 85,000 pounds - equivalent to over $130,000 at today's rates.
