Silverado HD, Touareg V10 TDI face off in diesel tug-of-war

A couple weeks ago, we watched a Chevrolet Silverado get dominated by a Dodge Ram Heavy Duty in a fullsize pickup tug-of-war, but in that truck's defense, Chevy's Vortec gas engine was no match for the torquey Cummins turbo diesel. For our next round of vehicular tug-of-war, a Duramax-powered Silverado HD takes on Volkswagen Touareg V10 TDI.
Now, on paper, putting the Duramax V8's 365 horsepower and 660 pound-feet of torque up against the V10's 310 hp and 553 lb-ft looks like an easy win for the Bowtie, but unfortunately, this battle has a similar result as the Dodge versus Chevy video, with the Silverado smoking its tires trying to move forward as it gets pulled backwards. Put another way: YouTube 2, Chevy Silverado 0.
It just goes to show, though, that big tires, bolt-on fender flares and goofy smoke stacks don't improve your towing abilities. Besides, what did the Silverado driver expect when the Touareg V10 TDI has towed a Boeing 747 in the past?

GM applies for LT5, LTX trademarks... are new small block variants coming?

Recently discovered General Motors trademark applications for LT4, LT5, LT88 and LTX have observers wondering what kind of high-performance offerings could be on their way. A new LT4 would mark a return of the engine designation first used on the Corvette Grand Sport, SLP Pontiac Firehawk and SLP Chevrolet Camaro SS from 1996 and 1997. Supposition at Corvette Forum - which provided advance intel on the C7 like these leaked images - believes a new LT4 could go into the high-performance trim of the next-gen, 2015 Camaro that would be more powerful than the 580-horsepower Camaro ZL1.
Seeing an LT5 again would also be déjà vu - in its former life it was a 5.7-liter V8 for the C4 Corvette ZR-1 from 1990-1994 designed by Lotus, producing from 370 hp to 405 hp. A mix of rumor and hope is that the new LT5 will be a supercharged evolution of the 6.2-liter LT1 (pictured) placed in the new C7 Corvette, and that it will go into the C7 version of the ZR1 pumping out something like 700 hp.
The LTX trademark is, as with that last letter, a complete mystery. If the "X" isn't a generic way to denote the whole LT family, it's wondered if it LTX could refer to a crate motor offering like the LSX.

eBay Find of the Day: Mario Andretti's personal 2009 Corvette ZR1

With victory in the the Indianapolis 500, a Formula 1 World Championship, a win in the Daytona 500 and too many other motorsports accomplishments to list, Mario Andretti stands among not just the greatest American racing drivers of all time, but the greatest drivers, full stop. Apparently, the champ is also a fan of speed when not on the track, because now there's a chance to own what is said tobe his personal 2009 Chevrolet Corvette ZR1 with just 12,872 miles on the clock. The eBay Motors auction page clearly shows Mario Andretti standing with the car, but the rest of the ad is admittedly short on details. The vehicle history report lists only one previous owner – ostensibly Andretti. The exterior is a handsome Blade Silver Metallic accompanied by a Dark Titanium leather interior. However, the seller keeps additional information to a minimum as well with the description simply stating, "This 2009 Chevy Corvette ZR1 is owned by Mario Andretti and has been garage kept all its life. It is fully loaded with all option on this car." The future buyer will get a seriously great car along with some huge bragging rights at any party by touting its ownership history. We've reached out to the seller for more particulars and provenance, and will update this story if we hear back. In the meantime, the auction for this C6 ends on Thursday, January 8, and currently the reserve isn't met. The price sits at a hefty $68,100 as of this writing, with six bids registered.
