Porsche still deciding on one or two new 911 plug-in hybrids

Back in March, Porsche CEO Oliver Blume told Autocar that the coming Porsche 911 plug-in hybrid "will be the most powerful 911 we've ever had." That quote portended a 992-series 911 with 700 horsepower or more. A new report in Auto Express, however, suggests Porsche is having energetic debates about just what the 911's hybrid strategy will be, and that the only agreed-upon plug-in hybrid 911 so far is a milder version to sit in the middle of the range. Putting all our rumors in a row, in January, Automobile reported on an electrically-assisted 911 with 485 hp and 561 pound-feet of torque. The new AE piece effectively endorses that, saying the mid-range hybrid would follow the program established by the all-wheel drive Cayenne e-Hybrid that produces a combined 455 hp and 516 lb-ft. The 911 would naturally use a flat-six instead of the Cayenne's 3.0-liter V6, and the sports car would be tuned for better sound response and sharper reflexes. AE says fuel economy for this hybrid should be at least 80 eMPG, with emissions of less than 80 grams per kilometer. The current base Carrera is currently rated at a maximum 38.2 mpg in the UK, with minimum emissions of 169 g/km. The hybrid, fitted with a double-clutch gearbox and Porsche's mechanical all-wheel-drive system, could run from a stop to 62 miles per hour in less than four seconds, making it more efficient than a base Carrera and much faster than a Carrera 4S. AE says there remains only "the potential for Porsche to add a second, more powerful hybrid 911," and says its sources claim that's what's "causing the most consternation behind closed doors." This one would be the twin-turbocharged, 700-hp beastie that, as a series production car, would have a hard time not usurping the 540-hp Turbo, 580-hp Turbo S, and 607-hp Turbo S Exclusive. True, the hybrid would be handicapped with a 550-pound battery pack, but the instant acceleration and handling benefits of electric AWD — with no connection between the axles — could provide the final edge over the other three. As such, it makes sense that there'd be a whole lot of debate about a flagship 911 hybrid. On the other hand, such a monster seems like an eventuality in view of Porsche's electrified aspirations, the lessons gained from the 918 Hybrid and the 919 Hybrid Le Mans racer, and the fact that CEO Blume has already spoken. The Stuttgart carmaker expects a sales mix of 25 percent electric, 25 percent hybrid, and 50 percent conventional powertrains by 2025.

Porsche Cayman S and Caterham 7 go head to head on the drag strip

We recently saw the standard Porsche Cayman go up against a Subaru WRX STI in a one-mile drag race with surprising results. Apparently, Evo had a similar idea of evaluating the Cayman's quickness. However, it opted for the more powerful S model and chose a flyweight Caterham Roadsport 140 as the challenger. Will the results of this battle be as close at the end of the kilometer-long (0.62-mile) drag?
Neither of these are cars you'd usually associate with drag racing, but they are nearly evenly matched. Evo selected them based on power-to-weight ratio, with the Caterham offering a scant 140 horsepower in a lithe 1,213-pound package. The Porsche is a quite svelte 2,910 pounds but has 325 hp to haul it around.
Of course, power-to-weight ratio isn't everything. There are a ton of other variables like aerodynamics and gearing that play a huge role, as well. Can the little Caterham's weight advantage overcome the better aero and additional power of the Porsche? Scroll down watch the video and find out.

Audi will submit emissions fix for 3.0 TDI V6 to EPA and CARB

Audi will develop a software update for the emissions control system on Volkswagen Group's 3.0 TDI V6 and will submit the changes to the Environmental Protection Agency and California Air Resources Board for approval. If the government regulators accept it, the tweaks could end the emissions problems for an estimated 85,000 of these engines in the US in Audi, Porsche, and VW models. However, the stop-sale still covers these vehicles until further notice. Audi admits in its statement to failing to disclose three "auxiliary emission control devices" on the V6 to regulators, and US law considers one of these systems a defeat device. VW Group offered the engine in the US on the Audi A6, A7, A8, Q5, and Q7 since the 2009 model year. The mill was also available on the VW Touareg and Porsche Cayenne. The EPA filed a violation against the 3.0 TDI on November 2 because the agency reported that the engine's software contained a defeat device to circumvent emissions tests. The regulator recently extended that notice to cover these powerplants in the US from the 2009 to 2016 model years. Audi's statement vaguely estimates the price of this problem to be in the "mid-double-digit millions of euros," and the automaker could face financial punishment by regulators. "Determinations regarding potential penalties and other remedies will be assessed as part of the investigation EPA has opened in conjunction with the US Department of Justice," an EPA spokesperson told Automotive News.

That is the result of the discussions held between a delegation from AUDI AG and the US Environmental Protection Agency (EPA) and the California Air Resources Board (CARB). The updated software will be installed as soon as it is approved by the authorities. The three brands Audi, Porsche and Volkswagen are affected. Audi estimates that the related expense will be in the mid-double-digit millions of euros.
