Dale Earnhardt, Jr. puts his Callaway Corvette and '55 Chevy on eBay

Dale Earnhardt, Jr. has put a couple of his personal cars up for sale on eBay. The first is a 1955 Chevy Bel Air that Junior had reworked by Funkmaster Flex, a bit of a diversion from Flex's more common Ford efforts. Junior's ride has a replacement chassis from Jim Meyer Racing, a 434 small-block tuned by Sharioff Racing to 500 horsepower, and truly thin rubber on what appear to be aluminum billet rims with Junior's former number 8 on the center caps. The interior is all custom and painted to match the outside, and those seats have been completely reupholstered. The second car is a 1999 Callaway C12, the 18th of 19 C12s built that year and featured in a 2002 issue of AutoWeek. It joined Earnhardt's private collection in 2004. Built on the base of a C5 Chevrolet Corvette and using a lot of technical know-how from Callaway's European racing program, the BMW #287 Blue Pearl C12 had its V8 bored out to 6.2 liters and graced with Callaway's Supernatural upgrade; it also has a Callaway coil-over suspension with adjustable dampers. There's new bodywork all around, and when new it cost about $200,000. At the time of writing bidding on the Bel Air was up to $80,100, the C12 was at $63,100. The auction ends Monday morning, and the winning bidders have the option of having their prizes autographed and retrieving the keys from Dale Jr himself if they're willing to go to Moorseville, NC.

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.

What car should James Robertson buy to drive his famous 21-mile commute?

The Internet has been abuzz this week with the story of Detroit resident James Robertson, the 56-year-old factory worker who has walked some 21 miles to work for the last 10 years. The Detroit Free Press brought Robertson's story to the fore, helping an online fundraising campaign to generate more than $275,000 (as of this writing). The original goal was just $5,000, or about enough to replace the used Honda that died on Robertson back in 2005, and left him walking. So, newly flush with funds, what's the perfect car for Robertson to buy? Let's look at the specifics of his situation, and try to pick out the best options. Here's what we know: Robertson's commute is (famously) 21 miles; he lives in downtown Detroit (for now) and seems pretty humble, so something very flashy is probably out; former Honda aside, his ties to the city (and statements about being a Ford fan) seem to indicate a Detroit Three company product is best; he's a single guy with a girlfriend; he's got to deal with Michigan weather, and the sometimes fickle snow removal processes in The D. Here are some choices: Ford F-150 Robertson is on record as being a Taurus fan, and after a decade of walking I've no doubt that the big sedan would offer a cozy respite. Still, as a car guy and a student of the industry, I'd have a hard time recommending a sedan so clearly in need of replacement. Especially when The Blue Oval has such great stuff within the rest of its roster. The 2015 F-150 seems almost perfect for Robertson. Opting for either of the new EcoBoost V6 engines should help keep fuel bills in reasonable check, while healthy ride height and four-wheel drive will get him to work on time even during the snowiest of snow days. Better still, with a fat options sheet and car-like ride quality, Robertson can have just about every amenity he might want, in a package that won't disrespect his blue-collar roots. Chevrolet Colorado You guys saw this one coming, right? The smaller footprint of the midsize Chevy pickup, relative to some of the other options here, should be an advantage for urban parking and driving. And again, 4x4 is an option for the nasty weather, the running costs should stay pretty low and there aren't many tech/luxury features that can't be had in-cabin. I'd go ahead and splash out on the Crew Cab bodystyle, too, just in case Robertson feels like starting a carpool.
