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:

Ecotricity offering 1,000 free EV miles to new customers

Ecotricity is offering electric vehicle drivers in the United Kingdom an lengthy incentive for using green energy: 1,000 miles of free fast charging per year. Called "Green Electricity + Car," the program will power customers' homes with renewable power allow them to charge their cars through Ecotricity's national network of fast chargers, which the company has named the Electric Highway. It makes complete sense for Ecotricity. "To get the greatest environmental benefit from an electric car, it needs to be charged using 100 percent green electricity from the wind and the sun – otherwise you're still powering it from dirty fossil fuels," wrote Dale Vince, founder of Ecotricity. Ecotricity, a UK-based producer of green energy, wants to bring fast charging to 90 percent of highway service stations around the UK in the near future and four fast chargers are installed per week under the Electric Highway campaign, the company says. Users can fast charge their EVs in 20-to-30 minutes. Ecotricity recently instituted a price freeze for all gas and electricity customers until April 1, reducing energy costs below what's being billed by the country's "Big Six" energy companies. Green Electricity + Car coincides with Volkswagen bringing its electric e-Up! to the British market. Volkswagen Group (UK) Limited imports VW, Audi, SEAT and Skoda brand vehicles and has signed a deal with Ecotricity as its official green energy supplier. Volkswagen Group customers purchasing an EV through one of its brands can take advantage of a new, reduced-cost Ecotricity tariff and a free smart meter installation. 08 February 2014 Green Electricity + Car Drivers of electric cars will receive 1,000 free miles every year with a new electricity tariff being launched by green energy company Ecotricity. Green Electricity + Car – will not only power customers homes with green energy but also their cars (either 100% electric or plug-in hybrids), plus they'll get free access to Ecotricity's national network of fast chargers[1] – the Electric Highway. This latest move comes after Ecotricity announced a price freeze for all gas and electricity customers until the end of winter (April 1st), making them cheaper[2] than the standard tariff of the Big Six energy companies.

Volkswagen's 261-mpg hand-built XL1 headed for Geneva

After years of rumors, development and testing, the Volkswagen XL1 is finally about to become a reality. The project that began life as a daring 1-Liter concept car in 2002, will finally get its production-ready curtain call at the Geneva Motor Show in just a few weeks.
As soon as it hits the streets, the two-seat XL1 will instantly become the most fuel-efficient and most aerodynamic production car in the world. The car uses a plug-in hybrid system to achieve mind-blowing consumption of just 0.9 liters of diesel fuel consumed every 100 kilometers (and average of roughly 261 miles per gallon). Plus, the XL1 can go up to 50 kilometers on its battery power alone. Coefficient of drag is a miniscule 0.189, thanks to a tiny frontal area and an obviously slippery shape.
XL1 power comes from a two-cylinder diesel motor connected to a seven-speed dual-clutch gearbox, while the 20 kW electric motor is fed by a lithium-ion battery. Both combine to give the XL1 performance figures that are, while not stirring, not shabby considering its extreme frugality: 0-62 miles per hour comes up in 12.7 seconds and top speed is nearly 146 mph.
