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?

Looking back at the Citation IV concept that likely shaped the GM EV1

Those who forget history are condemned to repeat it. We're not sure how that applies to the GM EV1, but we'd still like to share something from Autoline Daily, an online automotive new show with our friend John McElroy. He's been covering the business for decades now and recently found something interesting: pictures of the 1984 Chevrolet Citation IV concept, seen above. Displayed half a decade before the first electric concept that would become the EV1 (inset), McElroy says it's now clear that the elegant, aerodynamic EV1 took a lot of styling cues from the Citation IV, which was developed in part thanks to GM's new-at-the-time Aerodynamics Laboratory. We agree with him that the spats over the rear wheels, the flush glass, and the covered headlights all bear a certain kind of similarity between the two cars. That the colors almost match is a nice coincidence. The Impact (the concept version of the EV1) looked "frumpier," McElroy says, because it wasn't as long as the Citation. You can read a lot more about the Citation IV here and check out McElroy's thoughts in the video below. Find the Citation starting at around 3:45. This content is hosted by a third party.

This is what a 2017 Chevy Camaro Z28 could look like

The latest Camaro Z28, the enthusiast darling of the somewhat frumpy fifth-generation pony car, only hit the scene in 2014. It housed the wonderful 7.0-liter, naturally-aspirated LS7 small block V8 and featured a ton of aero bits. The trickest pieces may have been the dynamic spool valve shocks, legitimately race tech for the road. So with the new Camaro out in the wild, we were wondering what a new Z28 might look like, and thus, commissioned these renders based on our best guesses as to what a future Z28 might be. Since Chevy didn't stray too far from the Zeta-chassis Camaro formula with its new Alpha-based car, our vision of a new 2017 Camaro Z28 likewise is a sequel rather than a reboot. The exterior styling and aero details are similar, but sleeker. The defining and protruding front splitter is back, but it's smoothed slightly and better integrated. It shares quad exhaust pipes with the lowlier SS, but they're of the beveled Z06 variety, and sized up to a howitzer caliber. Instead of a weak faux rear fender vent, our version gains a real brake cooling duct. Some iconic elements, like the hood extractor vent and the large decklid spoiler, remain. What we can't see, we have to speculate on. As the track-focused, hardcore pony car in the Camaro lineup, the Z28 will have to do battle with the Ford Shelby Mustang GT350R. There's simply no avoiding it. And whereas Ford distinguished that car with a 5.2-liter, 526-horsepower, flat-plane-crank V8, Chevy is likely to look to the parts bin to find motivation. This isn't a knock; the LS and LT-series small block V8s are both numerous and power-dense. And there's one engine that seems to do the trick: the LSA, last seen in the old CTS-V and still on sale in the Camaro ZL1 (and of course, still being produced as a crate engine). In ZL1 form, the LSA makes about 580 hp, which is a nice margin over the GT350R. It's also a high-zoot but not top-of-the-line mill, having been mostly superseded by the 650-hp LT4. That puts our probable Z28 far enough behind the new CTS-V and current Corvette Z06 in the pecking order to be a safe bet, without hobbling it with the LT1 shared with the Camaro SS and regular Corvette. Will those trick spool-valve shocks from Multimatic make it to the Z28 again? Ford is taking the GT350R very seriously, and if the expensive but supremely capable suspension system is required to manhandle the Shelby at the track, you can bet that Chevy will pony up for it.
