2015 Volkswagen Touareg TDI Quick Spin [w/video]

There are two particularly great things about diesel-powered cars: torque and range. The 2015 Volkswagen Touareg TDI has both in spades. We put 190 miles on our test car, and upon return, the computer claimed we still had 490 miles to go. We weren't even averaging the EPA-estimaged 29 miles per gallon highway. Plus, that's in a sport-utility vehicle with tons of room and a whopping 406 pound-feet of torque. That said, our most recent adventure with the Touareg wasn't totally positive. This thing feels decidedly long in the tooth, despite a 2014 refresh. Driving Notes The Touareg TDI's powertrain really is the star of the show. The 3.0-liter, turbodiesel V6 has been in service since 2009, but it's still a dynamite engine. With 240 horsepower and 406 pound-feet of torque, the latter of which can be called upon at just 2,000 rpm, there's no shortage of thrust under your right foot. Turbo lag is an issue when you get aggressive with the throttle, but don't drive like a boob and you'll be fine. ZF's critically acclaimed eight-speed automatic delivers that power to all four wheels. But where other ZF-equipped vehicles deliver a crisper, sharper character, the TDI's trans is tuned for a far more relaxed driving experience. Upshifts are leisurely; the eight-speed keeps you right in the thick of the Touareg's broad torque curve. The suspension tuning follows a similar philosophy. It's far more comfortable than dynamic, soaking up all manner of bumps and general imperfections with aplomb. That said, the Touareg does not feel floaty or disconnected – just smooth. The greasy bits of the Touareg are very desirable, but the package they're wrapped in is less so. It's not that the interior or exterior designs are necessarily bad – fans of Earth tones will love our tester's Black Oak Brown Metallic paint and Cornsilk Beige interior – they're just kind of bland, or anonymous. The switchgear and buttons come from the Volkswagen parts bin, and while they're fine on a $20,000 Golf, these pieces aren't as appropriate in a vehicle that starts at more than twice the price. The dash plastics and faux wood don't look as nice as what's inside an Acura MDX, or even a Jeep Grand Cherokee. This mid-level Touareg TDI Lux starts at $57,580.

German authorities claim 2.8 million VW diesels evaded testing

While Volkswagen admits that there are 11 million diesel vehicles around the world that may be able to evade emissions testing, investigations by government authorities are starting to provide a glimpse of where some of those actually are. According to German Transport Minister Alexander Dobrindt, there are 2.8 million VWs in the country with the tech to cheat environmental rules, Reuters reports. In the US, at least 482,000 cars are believed to be affected. German regulators claim not knowing about the automaker's emissions testing evasions until quite recently, and Dobrindt didn't begin a fact-finding mission into the situation until just this week. Environmental agencies around the world have also begun their own inquiries into the scandal, including in Canada, South Korea, and many countries in Europe. In the US, where the story originally broke, the Department of Justice has started a criminal investigation into VW, and a maximum fine from the Environmental Protection Agency could tally $18 billion. The automaker has responded so far by setting aside about $7.3 billion to fix the affected models. CEO Martin Winterkorn is also already gone, and Porsche boss Matthias Muller is taking the top spot. The company's next moves still aren't clear, though. "VW needs to be very open about what has happened, how it was possible that this could happen to make sure that this never happens again in the future," an anonymous, top shareholder in the company said to Reuters.

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.
