New info on how VW, Porsche, Audi V6 TDI engine cheat works

The German newspaper Bild am Sonntag is reporting that US investigators have found three pieces of software that work in concert to turn off the emissions control equipment in certain diesel models after a set period of time. The engine in question, the 3.0-liter TDI turbodiesel, was found in certain Volkswagen Touareg, Audi Q7, and Porsche Cayenne models – the sale of which was suspended in the US late last year. Since most emissions compliance testing takes around 20 minutes, the software in the three VW Group models shuts off the emissions control equipment after 22 minutes, a straightforward end run around the testing. Remember that the 3.0-liter TDI engines aren't included in the big buyback and recall program announced for the smaller 2.0-liter, four-cylinder TDI engines. The 3.0-liter engines will likely get their own program, but we don't know when to expect it or exactly what it will look like. Last month, California rejected a proposed fix for the larger TDI engines, and VW went back to the drawing board. Since the company is unlikely to create two fixes, one for California and one for the rest of the nation, the company can't really proceed until they figure out a solution California will accept. The EPA hasn't officially commented on the report, and we don't know how Bild am Sonntag came across the information, but we'll be closely watching what emerges after this report. Related Video:

Best plug-in hybrid cars, SUVs and minivans for 2024

We’re fans of electric vehicles, but they have their shortcomings. TheyÂ’re not available in as wide of a range of body styles as gas-powered cars, and theyÂ’re still limited by range and charging infrastructure. Plug-in hybrids (PHEVs) offer a great compromise, though, allowing for all-electric driving, but also having a gas engine for when you need more power or to travel long distances. Choosing a plug-in hybrid vehicle also allows more options; for instance, you canÂ’t get an all-electric minivan in the U.S. Â… yet. But with those extra PHEV offerings, it might be difficult to know where to start shopping. WeÂ’ve narrowed it down a bit, bringing you the best plug-in hybrids for 2024, as voted on by Autoblog staff, in various segments to help you pick a great PHEV based on your budget and needs. Best luxury plug-in hybrid large/midsize SUV: Volvo XC90 Recharge Despite showing its age, the Volvo XC90 remains an excellent three-row crossover in terms of design, comfort and safety, and the XC90 Recharge plug-in hybrid only improves the formula with both power and efficiency. Interestingly, with the gas motor powering the front axle and the e-motor powering the rear, the XC90 Recharge operates as a rear-wheel-drive car when only using electric power, and front-wheel-drive when only using gas. The powertrain is good for 455 horsepower and 523 pound-feet of torque, with a 5-second 0-60 time. It can travel 32 miles on electricity alone. Runner-up: Porsche Cayenne E-Hybrid   Best mainstream plug-in hybrid large/midsize SUV: Jeep Grand Cherokee 4xe Do you want an American PHEV with style, refinement and off-road capability? The Jeep Grand Cherokee 4xe combines all that with a turbocharged 2.0-liter and electric motor good for 375 horsepower and 470 pound-feet of torque, as well as an electric range of 26 miles. That means you can enjoy your favorite trails in near silence and make fewer trips to the gas pump on the way there. Runner-up: Kia Sorento Plug In-Hybrid   Best luxury plug-in hybrid compact/subcompact SUV: Volvo XC60 Recharge Volvo borrows the formula from the XC90 and places it in a smaller package to get the XC60 Recharge. It has the same 455 horsepower and 523 pound-feet of torque, but it drops the 0-60 time to 4.5 seconds while offering 35 miles of electric range. You can even pony up for the Polestar Engineered trim to get the Ohlins suspension, Brembo brakes, 21-inch forged wheels and unique styling.

Porsche testing four-cylinder Boxster at the N?rburgring

Porsche recently introduced a four-cylinder version of the new Macan for markets outside of North America, carrying Zuffenhausen's first four-pot since the 968 ended its production run the better part of two decades ago. But you can bet the compact crossover won't be the only Porsche to get the four banger before all's said and done. These spy shots, we're told, are evidence of just that.
Spotted undergoing testing at the Nürburgring (where else), this modified Boxster, our spy photographers tell us, sounds more like a four-cylinder engine than the flat six that's powered (in displacements ranging from 2.5 liters to 3.4) every version of the little roadster since its introduction in 1996, the year after the last four-cylinder Porsche ended production.
The test mule is also wearing modified wheel arches and aerodynamic aids under the bumpers, front and rear. Just what they're doing there we're not sure, but we'll probably find out sooner or later.
