Porsche Will Never Downsize Engines to Under 2.0-Liters

Porsche endured some fury from enthusiasts for putting a four-cylinder motor in the 718 Cayman and Boxster but has promised it will never downsize engines to be smaller than 2.0-liters.

The catch is that it doesn’t make sense from a performance standpoint to downsize the internal combustion engine to that point, so the alternative would be to go the full electric powertrain route, Michael Steiner, member of the executive board for research and development of Porsche, said during an interview at the 2017 L.A. Auto Show.

“We could do more downsizing, even below 2.0-liters, but if you would like to have good performance and very precise and fast reaction to any movement of the gas pedal, you need torque, not only power,” Steiner said, adding that hybridization would be a solution for supplying torque. “At some point, it would make no more sense to downsize the combustion engine and put more and more electric energy into the vehicle. You come to the point where it doesn’t make sense anymore, so we would do a full electric.”

Steiner explains that downsizing more is possible, as the 919 race car has proved, even as small as 1.0-liter, but the application doesn’t make as much sense for road-going production cars.

“From an engineering point of view, we did our experiment on the racetrack with the 919. This engine is downsized to the extreme,” he said. The 919 engine displaced just 2.0-liters but output more than 900 horsepower. This was only made possible because of the electrified powertrain, which is able to supply loads of torque. The system would just be too heavy and complicated for a road car, so a fully electric would make more sense to get purer Porsche performance.

Waterfest Moves to Atco Dragway

Waterfest 24 will be held at Atco Dragway, in Atco, New Jersey. The summer event will take place at its new venue on July 21 and 22. Long held in Englishtown, New Jersey, the festival has been such a large part of the VW scene that the latest iteration of the Golf even comes with optional “Englishtown” wheels . The new venue, however, is an NHRA drag track a scant 52 miles southwest of Englishtown. The ¼ mile drag track opened in 1960, which makes it the oldest drag strip in New Jersey. The announcement came today on a social media post that announced the new location. Waterfest is North America’s largest VW/Audi show. As many 20,000 people show up for the annual show, making the second largest show in the world—with Worthersee being number one. 2018 will be Waterfest’s 24 th year in existence.

Macau Gets Messy with 16-Car Pileup

The Macau Grand Prix is always good for an accident or two or 16— you may remember Audi’s race ending crash last year —and this year’s event didn’t disappoint. It didn’t take long for things to get messy on the tight road circuit. On the opening lap of the qualifying race a 16-car pileup caused the race to be suspended. Things kicked off when Daniel Juncadella hit a wall on the exit of Police bend, one of the tightest parts of the already tight circuit. The following car of Raffaele Marciello was able to avoid the carnage, but Laurens Vanthoor, who was in the upside-down Audi that ended the race last year, could not avoid Juncadella and together they blocked up the road pretty much completely. “I couldn’t see him [Juncadella] at first. Then I saw the car standing still,” Vanthoor told Motorsport. “I tried to brake but it was just understeering and I couldn’t do anything. There’s room for one car there and you’re blind.” Fourteen more cars would eventually crash into the corner c

The First of its Kind: Integrated Engineering Releases Highly-Anticipated IE450T MK6 Golf R Turbo Kit

After two long years of development, the team at Integrated Engineering has finally announced the release of their IE450T kit for the MK6 Golf R. With their turbo kit bolted on right out of the box, the sport AWD hatch is transformed into a 450bhp monster, with hardly any noticeable increase in spool time. In fact, 435 ft-lbs of torque are achieved at all four wheels, at a mere 3300rpm! By now you are probably asking yourself how this is even possible on a 2.0L engine that made nearly half that power from the factory. By employing true twin-scroll technology into the cast turbo manifold and pairing it with a state-of-the-art BorgWarner EFR turbocharger, IE was able to keep spool time at a minimum and bring the fastest-spooling big turbo setup to the market. “We wanted to offer a kit that would dramatically increase the power output without making the car lose its amazing street-friendly drivability,” mentioned one of the IE engineers. We are told the IE450T leaves the car driving jus
