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. You can watch the video above, and feel free to try and dissect the results yourselves in the comments below. Related Video:

MotorWeek recalls the glory days of the VW Cabriolet

Remember the car that the rich, very attractive girl in your high school got on her 16th birthday? Was it a Volkswagen Cabriolet? But time marches on, and the boxy convertibles have attained a certain quirky coolness in the modern day. MotorWeek weighs in with a look at the 1989 model in the latest entry in its Retro Review series. MotorWeek actually comes away rather impressed with the Cabriolet, especially its handling. The show doesn't even complain about the big roll bar over the center of the car that has always looked more like a basket handle than a safety aid. Host John Davis must have enjoyed driving the droptop VW, too – despite his very '80s windbreaker and polo shirt ensemble, he was sporting quite the tan in this clip. The small, inexpensive convertible segment has largely disappeared today, but as MotorWeek shows by comparing the Cabriolet to the Chrysler LeBaron and Chevrolet Cavalier, it wasn't always this way. Take a ride in VW's droptop to see how it scores.

Volkswagen Cross Up! headed for production after Geneva reveal

The last time we saw the Volkswagen Cross Up!, it was sitting out in the snow in prototype form, but the next time we'll see this slightly more rugged version of the diminutive Up! hatchback will be when it makes its production debut at the Geneva Motor Show next month. Looking like a micro-crossover with its raised ground clearance and black cladding, the Cross Up! will be the fourth "Cross" model for VW (after the CrossPolo, CrossGolf and CrossTouran) when it goes on sale this summer in mainland Europe (UK sales remain up in the air and US sales are highly unlikely).
Overall, the styling of the production Cross Up! has stayed fairly true to the 2011 concept car, including the front and rear fascias that offer a more rugged look, stocky 16-inch wheels and roof rack side rails. Inside, this model will get unique interior enhancements such as "Cross Up!" sill plates and an instrument panel available in red, black or silver. Like the regular Up!, the Cross Up! is powered by a 74-horsepower, 1.0-liter three-cylinder engine paired to a five-speed manual transmission, and it doesn't look like all-wheel drive will be part of the picture. For more details on the upcoming Cross Up!, check out VW's press release posted below.
