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:

Recharge Wrap-up: Jaguar Land Rover talks EVs, Batteries should be modular

A new study out of Germany suggests adopting a modular approach to battery offerings in plug-in hybrid and extended range electric vehicles. Automakers could offer the same car with different battery sizes (and different costs, accordingly) to drivers depending on their driving ranges. This would optimize the total cost of ownership for various drivers better than the current approach. Developing a modular battery design and offering appropriate batteries for different customers "is the key for electric powertrains to meet customer expectations and become cost competitive against conventional technologies," according to the report from the Institute of Vehicle Concepts, German Aerospace Center. Learn more at Green Car Congress. Jaguar and Land Rover are looking to offer more electric driving from their vehicles. Wolfgang Ziebart, head of product development for Jaguar Land Rover, said in an interview that its hybrid system is being tweaked for more electric power and "downsized" combustion. He also said the likely target market for EVs would be second and third vehicles, rather than primary vehicles for urban driving. Within that market, Europeans look for something smaller, while American drivers lean toward larger luxury vehicles for their second car. Ziebart uses the Tesla Model S as an example of American tastes, and compares its size to that of the Jaguar XJ. Read more at Automotive News Europe. Thailand will likely approve a Volkswagen factory as early as next week. A German newspaper suggests that Thailand's Board of Investment is set to greenlight the plant, which is planned for a site near the Port of Bangkok. Thailand is a relatively large and growing auto manufacturing country, which seeks to be a major producer of eco-friendly vehicles. The country's "Eco2" program would provide incentives to Volkswagen if it builds clean cars and meets certain production targets. Read more at Reuters. Formula E has chosen Sky Deutschland for broadcasting rights in the German market. The deal includes television rights, as well as online broadcasting. Sky Deutschland has 3.8 million subscribers in Germany and Austria. Showing the races on Germany's largest pay television provider should help generate interest for the series, particularly the Berlin ePrix - the inaugural season's penultimate race - scheduled for May 30, 2015.

2015 VW Beetle GRC packs 553 rallycrossing horsepower

In case you couldn't tell from all the wings and vents, this is not your average Volkswagen Beetle. It's the rally machine Tanner Foust and Scott Speed will be driving in the Global Rallycross Championship this year. Don't let the retro form fool you – it is an absolute beast. Last year's Beetle GRC packed a 1.6-liter turbo four good for an astonishing 544 horsepower and 387 pound-feet of torque, but the new one does one better: it now features a 2.0-liter turbo four good for 553 hp and 465 lb-ft. That's right – in a Beetle. It's also got ZF dampers, 9.5 inches of suspension travel, 14-inch front brake discs with four-piston calipers packed into 17-inch wheels and, of course, all-wheel drive. The result? 0-60 in – wait for it – two seconds flat (or thereabouts). It's geared low so it'll only top out at around 125 miles per hour, but that's all it needs for the short tracks on which it's designed to compete. Foust and Speed will be driving this beast for Andretti Autosport in the 2015 championship that kicks off at the end of May in Ft. Lauderdale. Both have quite the act to follow as Foust won back-to-back titles in 2011 and 2012, and former F1 driver Speed won three rounds last season to finish third in the standings.

In 2015, the team will be on the attack with two Beetle GRC race cars, which debuted in the final races of 2014. This rallycross car is the ultimate expression of the third-generation Beetle. Designed and engineered from the outset as a GRC car, it features a sequential six-speed transmission, with a fixed-ratio all-wheel-drive system that features multiplate limited-slip differentials at the front and rear. For the 2015 season, the team has chosen to change the engine specification from the car that ran in selected rounds of the 2014 series. In place of that car's 1.6-liter turbocharged and intercooled TSI® four-cylinder engine, there is now a 2.0-liter TSI engine that produces 553 horsepower and 465 pound-feet of torque, compared to 544 hp and 387 lb-ft for the 2014 car.
