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.

What the Volkswagen I.D. concept tells us about the post-TDI future

If you've been paying attention, 2016 hasn't been a great year for Volkswagen. The TDI scandal removed VW's last crutch between our internal combustion present and the electric future, and so the company found itself scrambling to shift resources to show what's next right now. It's naive to assume that this is truly the sort of fairytale comeback story that VW's spin doctors would have us all believe, but it's notable that instead of flinching or pointing fingers, the engineers got to work. What they've produced is the I.D. concept, the third wave in VW's volume car history after the Beetle and Golf. The transaxle Golf was more than simply an updated Beetle, and likewise the I.D. is more than an electrified Golf. VW says the I.D. won't replace the Golf, but they said the same thing about that car replacing the Beetle. It's only a matter of time. VW says the I.D. won't replace the Golf, but they said the same thing about that car replacing the Beetle. It's only a matter of time. The I.D. approach is refreshingly simple: no carbon fiber chassis, no exotic battery chemistry, no outrageous concept car styling. The MEB chassis (the German acronym for modular electric platform) is made out of a traditional mix of high-strength steel grades to save costs and utilize existing factories. The battery is integral, not swappable, to reduce complexity and increase structural rigidity. It's also uses lithium-ion chemistry because of a proven track record and an existing (albeit deficient) supply chain. Contrast that with the e-Golf, which shares its chassis with the conventional internal-combustion cars. Fitting the battery and its ancillary systems became complicated and expensive. The skateboard installation in the I.D. will allow the pack to be optimized for the space available, reducing costs. As we've already reported, MEB will be shared across all VW Group brands to achieve an economy of scale, and the modular platform can be stretched to the size of roughly a Passat and down to a car slightly smaller than the I.D. It can be given all-wheel drive, although VW's e-mobility chief Christian Senger is quick to point out that the standard rear-drive configuration provides plenty of traction because of optimal weight distribution achieved with battery in the middle of the chassis. It makes all-wheel drive more of a bonus rather than a necessity in bad weather.

Everybody's doing flying cars, so why aren't we soaring over traffic already?

"Where's my flying car?" has been the meme for impending technology that never materializes since before there were memes. And the trough of disillusionment for vehicles that can take to sky continues to nosedive, despite a nonstop fascination with flying cars and a recent rash of announcements about the technology, particularly from traditional automakers. Earlier this month, Toyota applied for an eye-popping patent for a flying car that has wheels with spring-loaded pop-out helicopter rotors. The patent filing says the wheels/rotors would be electrically powered, while in on-land mode the vehicle would have differential steering like tracked vehicles such as tanks and bulldozers. At an airshow in July, Aston Martin unveiled its Volante Vision Concept, an autonomous hybrid-electric vertical takeoff and landing (VTOL) vehicle it developed with Rolls-Royce. Aston says the Volante can fly at top speeds of around 200 mph and bills it as a luxury car for the skies. Audi used the Geneva Motor Show in March to unveil a flying car concept called the Pop.Up Next it developed with Airbus and Italdesign. If the Pop.Up Next, an electric and autonomous quadcopter/city car combo, gets stuck in traffic, an app can be used to summon an Airbus-developed drone to pick up the passenger compartment pod, leaving the chassis behind. Audi said that the Pop.Up Next is a "flexible on-demand concept that could open up mobility in the third dimension to people in cities." But Audi also acknowledged that at this point it has no plans to develop it. The cash-stoked, skies-the-limit Silicon Valley tech crowd is also bullish on flying cars. The startup Kitty Hawk that's backed by Google co-founder Larry Page announced in June that it's taking pre-orders for its single-seat electric Flyer that's powered by 10 propellers and is capable of vertical takeoffs and landings. The current version can only fly up to 20 mph and 10 feet in the air and has a flight time of just 12 to 20 minutes on a full charge. The Flyer is considered a recreational vehicle, so doesn't require a pilot's license. Uber says it plans to launch its more ambitious Elevate program and UberAIR service in 2023. "Uber customers will be able to push a button and get a flight on-demand with uberAIR in Dallas, Los Angeles and a third international market," Uber Elevate promises on its website.
