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:

1000-hp Mk1 VW Golf is terrifyingly cool

There are plenty of things to love about the Mk1 Volkswgen Golf. The machine's horsepower isn't one of them. From the factory, the little hatch cranked a breathy 112 horsepower from the most robust form of its 1.8-liter four-cylinder engine. Boba motoring, however, has taken that figure and multiplied it by a factor of nearly 10. If 1,000 horsepower sounds terrifying in a machine with a wheelbase of just 94.5 inches, it should. A massive Garrett GTX4202R turbo force-feeds the little mill through a tweaked 16-valve KR head. The crew calls the beast the 16Vampir, and we think that's fitting.
Of course, we'd wager you quit reading right about the time you set your eyes on that headline. Those of you who've stuck around this long can point yourselves below to see the maniacal creation in action. You won't be disappointed.

Lincoln Aviator returns, VW ponders pickups, and Subaru Forester endures

NEW YORK – Volkswagen is taking a hard look at a pickup truck, the Lincoln Aviator is back, and you love old Subarus (we'll explain). The New York Auto Show returned last week with flair and a wide range of promising reveals. Let's break down some of the big news, plus a few things you might have missed. News: Ford is fortifying Lincoln with the Aviator SUV Views: Doing a mid-size SUV is obvious. Calling it the Aviator wasn't. I like it. Using Navigator design cues, this thing looks the part and should give Lincoln some energy and sales volume. Not playing in the midsize SUV segment has been a mistake for Ford's luxury brand, and the Aviator should fill a much-needed hole. Props to Lincoln for dusting off the Aviator name, most recently used on a rebadged Ford Explorer built in 2003-2005. It sounds classy and historic, like something from 1930s, even though it only dates to the tail end of the " Friends" era. Speaking of names, when the MKC gets a new one, Lincoln should dust off Zephyr, a moniker it actually used in the '30s and then briefly in the early 2000s. Why use the Aviator name? Jim Farley, Ford's president of global markets, said it's about reminding consumers that Ford has traditionally built strong SUVs. "I think in a way the legacy is falling in love with what we do best," he said. "We wanted to go back to our roots. We know how to do this well." Farley also said the Aviator could prove to be Lincoln's bestseller. The Aviator was well-received in New York, earning our Best in Show award and garnering cautiously optimistic reactions from some analysts. "Lincoln ran this experiment once before ... differences in the market conditions, stronger differentiation and appetite for utility vehicles may prove a different story for this Aviator," IHS analyst Stephanie Brinley said. View 19 Photos News: VW surprised the car world with the Atlas Tanoak pickup concept Views: Good move. VW should build this. The concept is based on a longer version of the Atlas platform and would take aim at the midsize truck segment. VW is using this prototype to "gauge the reactions" of automotive influencers, but make no mistake, the Tanoak is totally doable. Using Atlas bones and mechanicals punched up with rugged styling and some soft-road capability, the Tanoak would grow VW's portfolio in a smart way. The Atlas Cross Sport concept, also revealed in New York, signals that Atlas expansion is already underway.
