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:

Autoblog Minute: VW finds CO2 'irregularities', Takata dropped by automakers, SEMA recap

Volkswagen's diesel emissions scandal gets a new wrinkle, US regulators hit Takata Corporation with a substantial fine, and we head to Las Vegas for a look at tuner paradise at the 2015 SEMA show. Autoblog senior editor Greg Migliore reports on this edition of Autoblog Minute Weekly Recap. Show full video transcript text [00:00:00] Volkswagen's diesel emissions scandal gets a new wrinkle. US regulators issue a significant fine to Takata Corporation. And we take a peek inside tuner paradise at the 2015 SEMA show. I'm senior editor Greg Migliore and this is your Autoblog Minute Weekly Recap. The VW diesel emissions scandal, first brought to light in September, gets a new wrinkle, as an internal investigation by the German automaker revealed [00:00:30] irregularities in CO2 emissions that could affect approximately 800,000 vehicles. VW estimates the issue could pose a 2-billion euro economic risk. VW claims that most of the vehicles affected have diesel engines, but industry analysts say a 1.4-liter gas engine is also affected. VW says that fuel consumption figures were set too low during the CO2 certification process. During all of this, sales of some diesel-powered Volkswagen, Audi, and Porsche models [00:01:00] have been halted. Takata Corporation is back in the news in connection with its deadly airbag scandal. Federal regulators fined Takata $70 million. If the parts supplier does not comply, the fine could balloon to $200 million. Takata was also dropped this week by its biggest customer, Honda. And now, Toyota and Mazda will be following Honda's lead in dropping Takata. We're also hearing that Mitsubishi and Subaru are considering a switch in air-bag inflator suppliers. SEMA 2015 [00:01:30] came and went. We saw offerings from Mopar, like the AWD Challenger concept. Honda unveiled a Ridgeline that it will race at the Baja 1000, which gives us a hint at what future production model could look like. The celebrity presence was also felt in Vegas as it always is. Kid Rock brought a Duramax Diesel Chevy Silverado, and Acura restored and presented Ludacris with his now famous 1993 Acura Legend. Those are the highlights from the week that was. Be sure to come back on Saturday for my full recap, [00:02:00] where I'll have some added insight into Hyundai's foray into the luxury sector. For Autoblog, I'm Greg Migliore.

Porsche says half of its sales will be electric by 2023

Porsche, whose presence in the plug-in vehicle market has been pretty minimal, now plans to substantially boost its commitment to electric vehicles in the next few years. The German luxury automaker intends to dedicate up to half its annual production to electric vehicles by 2023, Electrek reported, citing comments CEO Oliver Blume made to German publication Manager Magazin. Specifically, the company says it will be able to produce as many as 60,000 EVs annually from its Zuffenhausen factory in Germany. First and foremost will be Porsche's Mission E, which is slated to debut in 2019. That model will be able to go about 310 miles on a full charge (via the more generous New European Driving Cycle, or NEDC). Porsche first showed off a concept version of that 590-horsepower beast at the Frankfurt Motor Show in 2015. The company hasn't hinted at pricing for the car, which will have a 90-kilowatt battery and will jet from 0 to 60 miles per hour in a tidy 3.5 seconds, but expect it to be well into six figures. Porsche also plans an all-electric version of the Macan, its biggest seller. But Porsche's math indicates bigger plans than that. Porsche delivered nearly 238,000 vehicles last year, so an output of 60,000 EVs at Zuffenhausen is only a quarter of the total, not half. You can assume then that Porsche has plans to electrify other models that it hasn't announced yet, built at other factories. It might also be counting hybrids in its "half" projection. Last month, Porsche decided to discontinue its plans for a plug-in hybrid variant of its iconic 911 model, suggesting a temporary pullback of sorts. Then again, in April, reports surfaced that Porsche and Audi, both owned by Volkswagen, were collaborating on vehicle-electrification technology as well as autonomous driving advancement. Porsche's green-car sales have been so thin that Autoblog last year officially pulled the German automaker off of its monthly green-car sales tally. For 2015, the most recent year we tracked, Porsche sold 1,738 plug-in vehicles, about the same as 2014.
