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:

Volkswagen Motorsport cranks out Golf touring car

Just when you thought Volkswagen had done all the hot Golfs we could handle, its motorsports division has come out with an even hotter one. This racing version is built to compete in the Touringcar Racer International Series (TCR) across Europe and Asia, and certainly looks the part. Based on the production Golf hatchback we all know, the TCR competition version promises to be to circuit-based touring car racing what the Polo R WRC is to the rally stage. And that little pocket rocket has been positively dominating the World Rally Championship. Developed in conjunction with Seat's racing department and Liqui Moly Team Engstler, the Golf touring car packs the 2.0-liter turbo four from the Golf R. Only instead of 292 horsepower and 280 pound-feet of torque in the production version, it's been tuned to channel 330 hp and 302 lb-ft to the front wheels (instead of all four) through a six-speed dual-clutch transmission. It rides on 18-inch alloys fitted to a track widened by nearly a foot and a half, along with a competition-spec aero kit to keep it glued to the tarmac and a stripped-out cockpit. Though the 2015 TCR series is already under way, a pair of these racing Golfs will be entered in the upcoming round at the Red Bull Ring in Austria, before the series heads off to Singapore (in support of the F1 grand prix there) and Thailand ahead of the final round in Macau. If everything goes well, customer teams will be able to pick these up and enter them in next year's championship. Volkswagen develops new Golf for the racetrack - Concept car for customer racing, in line with new TCR regulations - Production-based touring car with 330 hp, front-wheel drive and six-speed DSG gearbox - First competitive test this weekend in Spielberg (A) Wolfsburg (09 July 2015). A new Golf for the racetrack: Volkswagen Motorsport is developing its first racing car based on the seventh generation Golf. The production-based, 330-hp concept car is assembled in accordance with TCR regulations and is intended to help Volkswagen evaluate a potential customer racing programme from the 2016 season onwards. In order to accelerate the development of the car, the new Golf will be tested under competitive conditions between now and the end of the season: as cooperation partner, the Liqui Moly Team Engstler will run two cars at the eighth round of the Touringcar Racer International Series (TCR) at the Red Bull Ring in Spielberg (A).

VW launches special edition Touareg X

Volkswagen is no stranger to special editions, but its Touareg SUV has remained largely unspecial in terms of exclusive trims or unique packages. That's changed with the announcement of the Touareg X, a 1,000-unit run based on the V6 TDI Lux trim - mid-range diesel model, between the navigation-equipped TDI Sport and the TDI R-Line.
The already special Touareg gets 19-inch "Moab" wheels, LED taillights (to go along with its LED DRLs) and "Touareg X" badging, while all 1,000 units will be painted Moonlight Blue Pearl. Tweaks in the cabin are equally light, with a black-on-black-on-black color scheme dominating - black Vienna leather, a black headliner and piano black trim. Aluminum bits make an appearance in the form of the door sills and pedals, although that's about it.
Other than those few aesthetic tweaks, the Touareg X is equipped largely like the Touareg Lux on which it's based. That means navigation, a panoramic sunroof, power seats, LED running lights, dual-zone air conditioning and heated power seats, among other tech pieces. Pricing starts at $56,170, making for a slight bump of $1,195 over the standard Touareg Lux.
