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:

Wagons make a bit of a comeback, with new models, sales on the rise

Consider this an official invitation to hop on the wagon bandwagon. There's still tons of room because, well, it's a wagon (and market share is still extremely small). But according to new data, the segment is growing. According to a report from Bloomberg, using data from Edmunds.com, roughly 211,600 Americans purchased wagons in 2018. That is technically down from the 237,600 sold in 2017, but wagon sales in the U.S. are up 29 percent from where they were five years ago. It's also the third year in a row that wagon sales broke the 200,000 mark. The sales trends have been somewhat representative of the availability of wagons. New models have debuted during the past 5 years and therefore offer more opportunity at more brands to buy wagons. In addition to more modest cars such as the Volkswagen Golf Sportwagen, several luxury and performance brands are offering wagons today, such as Mercedes-Benz, Audi, Porsche, Jaguar, Volvo and Buick. (Bloomberg's headlines make the point that "crossovers are for the Kardashians," and wagons are just, well, classier.) This uptick in brand-name availability, as well as extremely well-executed design on most of the wagons currently available, has helped increase the segment's desirability. That, and its ability to better accomplish the same tasks at hand while standing out from the crossover and SUV crowd. Still, the posted numbers represent a small fraction of the total vehicles sold. According to the data, wagons only held a 1.4 percent market share in 2017, the segment's best recent year. Wagons hold a steadfast place in America's past, and they're writing an interesting new story. With the downturn in traditional cars, they may continue to create an unexpected narrative.

Rivian R1T, Mini Cooper Electric owners happiest with their EVs

The J.D. Power 2023 U.S. Electric Vehicle Experience (EVX) Ownership Study is out, and there's change at the top. With the swelling adoption of electric vehicles in the U.S. over in the past two years especially, the third year of the EVX study changes focus to first-time EV buyers. Those two factors encouraged change at the top of both premium and mass-market segments. Among premium EVs, the Rivian R1T pickup scored overall victory in its first year of eligibility with a satisfaction score of 794 out of 1,000. The Tesla Model 3 takes second place with 759 points. Tesla had won the top two premium spots in the study in 2021 and in 2022. The average score in the premium segment was 756. The Tesla Model Y (754), Audi E-Tron (735), and Polestar 2 (724) filled out the list of the five eligible models this year. Among the ten eligible mass-market vehicles, the Mini Cooper Electric nabbed the overall win by scoring 782. The Kia EV6 came second with 762 points, keeping Kia in the top two; the Kia Niro EV won the mass-market segment the previous two years. The Ford Mustang Mach-E (742), Hyundai Ioniq 5 (738), and Volkswagen ID.4 (735) completed the top five, the Niro EV (733) in sixth. All were above the segment average of 730. The four models fell below the segment average were the Ford F-150 Lightning (723), Chevrolet Bolt EUV (716), Chevrolet Bolt (711), and Nissan Leaf (698). How are the scores derived? J.D. Power worked with EV app maker and research firm PlugShare to get owner responses in ten areas: accuracy of stated battery range; availability of public charging stations; battery range; cost of ownership; driving enjoyment; ease of charging at home; interior and exterior styling; safety and technology features; service experience; and vehicle quality and reliability. Brent Gruber, executive director of the EV practice at J.D. Power, said, "Recent vehicle launches from both new brands and traditional automakers have had a profound effect on what factors are most important in the ownership experience. Today’s EV owners are looking for quality, reliability, driving enjoyment, safety and technology features." The Mini, in fact, scored highest of any premium and mass-market EV in the studyÂ’s highest-weighted index factor, quality and reliability.
