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?

2019 Hyundai Veloster N vs. hot hatch rivals: How they compare on paper

The highly anticipated top-rung of the Veloster line, the 2019 Hyundai Veloster N, is on the verge of hitting dealers. And the company has finally dropped all the specifications, and perhaps most importantly, the car's official pricing that starts at $27,785. So you know what that means: it's time to see how it stacks up to the competition. The Veloster N falls into an interesting niche in the hot hatch world. It's the most potent of its model line, but it's not as powerful as vehicles such as the Civic Type R, Focus RS and Golf R. But it also doesn't have the price of those cars. As such, we decided to compare it with other sub-$30,000 sport compacts. We examined each car's power, fuel economy, size and pricing. You can see all the vital statistics in the chart below, as well as additional photos and analysis after that. As always, specifications only tell so much, so be sure to check out our detailed reviews of these cars. Also be sure to check out our comparison tool if you want to compare these with other models. Engines, transmissions and performance Three of these cars are impressively close in output, and one is, well, not. The Veloster N Performance Pack is the clear horsepower champion with 275 ponies. Second place for power is almost tied, with the Focus ST's 252 horses edging out the standard Veloster N's 250. The Focus ST also boasts the most torque at 270 pound-feet. The GTI nearly matches both Velosters with its 258 pound-feet, but its 228 horsepower is far behind the Korean and American entries. The Civic Si lags far behind with just 205 horsepower and 192 pound-feet of torque from the only 1.5-liter engine here. The rest use 2.0-liter engines. 2019 Hyundai Veloster N View 47 Photos Every vehicle here sends its power to the front wheels, and three of the four do so exclusively with 6-speed manual transmissions. That means that if you don't want to work a clutch, your only option is the VW GTI. It offers a 7-speed dual-clutch transmission, which, like all VW Group dual-clutch units, is really smooth and fast. While the Civic Si is at the back of the pack in terms of power, it does make up for it somewhat with excellent fuel economy. It's capable of hitting 38 mpg on the highway, and city mileage is rated at a solid 28 mpg. The Veloster N is at the back of the pack here, with its highway mileage the same as the Civic's city economy. Its city fuel economy is just 22 mpg.

VW Jetta TDI dyno shows HP loss trying to recreate cheat mode

Volkswagen is working on a fix for diesel-engined vehicles that are out of compliance with emissions regulations in the US and other countries. We're told that engineers will be presenting a solution internally sometime this month, but that doesn't mean we'll actually see it in the wild this month. One big question we have about the coming fix is, will it affect the car's performance? That question relates to another we have about the engine as it is: How much performance would the 2.0-liter diesel lose right now if it were turned down to pass US emissions? The Fast Lane Car tried to sketch some answers by going to a shop in Denver, Colorado to run a 2011 Jetta TDI with a six-speed DSG transmission on an all-wheel-drive dyno. The thinking was that if you ran all four wheels the car would think it was on the road, whereas if you ran only two the car might think it's being tested. We'll get straight to the numbers: the stock sedan is quoted at 140 horsepower and 236 pound-feet of torque. When run with all four wheels turning it produced an uncorrected 114 hp and 214 lb-ft at the wheels. When run with just two wheels in motion the Jetta got 113 hp and 188 lb-ft at the wheels. Reading the graph, we're told that power differences between the two runs were as much as 15 hp and 32 lb-ft. You'll need to take some salt with these numbers, though, because the dyno and test protocol in the video are nothing like those used by the EPA. The shop attempts to trick the Jetta into 'emissions testing mode' by using the front wheels only for the two-wheel-drive run, but we have a feeling the software code at issue is far more sophisticated than that, since the ICCT, UVA, the EPA, and CARB investigated the situation for more than a year and couldn't figure out. Also, the technician adjusts for being a mile above sea level with a correction factor of 1.2 applied to horsepower and torque, which inflates the disparity in the final power differences over the two runs. Go to YouTube and read the lengthy comments on the video left by Andrew Price for a more thorough dissection of what could explain TFL's disparities.
