Porsche Unveils New 911 RSR GTE With 4.2-Liter Flat-Six


Porsche has taken off the covers to the all-new 911 RSR GTE racer at the Goodwood Festival of Speed.

The new Porsche 911 RSR GTE will compete in the 2019-2020 FIA World Endurance Championship set to kick off at Silverstone on September 1st and will then become available to customer teams for the 2020-2021 season. It may look similar to the outgoing RSR GTE, but 95 per cent of its parts are brand new.


The most significant change is the fitment of a bespoke 4.2-liter naturally aspirated flat-six that pumps out 507 HP. This is the largest capacity engine fitted to a 911 racer ever and replaces the outgoing 4.0-liter unit. Power is sent to the rear wheels via a six-speed sequential transmission with a three-disc carbon race clutch. The new RSR even features side-exiting exhausts, which allowed for the design of a more effective rear diffuser, thus generating greater downforce.

Like its predecessor, the new RSR GTE features an aluminum-steel composite body shell and carbon fiber reinforced plastic panels, and it tips the scales at a mere 1,245 kg (2,744 lbs).


The launch of the new 911 RSR GTE shows that Porsche is continuing to find ways to develop and improve its signature flat-six. Both the current GT3 and GT3 RS use 4.0-liter engines with over 500 HP, and if the new 4.2-liter proves successful on the racetrack, a development might eventually find its way into a road-going Porsche GT model.

Limited Edition Ford GT 'Competition Series' Is All About The Track

Image
Ford's new GT Competition Series was built with weight-saving in mind, but also with an improved center of gravity for better road-holding. Among its features, you'll notice the lightweight carbon fiber racing stripes, A-Pillars and side mirrors, as well as the unique race-inspired Perspex acrylic engine hatch with integrated venting. Thanks to the manual latch and the carbon fiber prop rod, weight near the roof has been reduced, though Ford engineers went even further in their quest to make the car lighter, by making the bulkhead Gorilla Glass behind the driver about half as thick (and as light) as on other models. "The Ford GT has racing in its blood," said Ford exec Raj Nair, while adding that the Competition Series "was developed with the most hardcore track enthusiasts in mind, providing a tailored set of lightweight features and unique livery to match." There are also plenty of remaining performance features from the production car, such as ...

Volkswagen T-Roc Cabriolet Is A Crossover For Droptop Lovers

Image
Droptop crossovers have always been rather odd and the T-Roc Cabriolet is no different. It will be the only convertible Volkswagen on sale for the foreseeable future and will celebrate its public debut at the Frankfurt Motor Show in September. Rather than simply removing the roof of the standard T-Roc, Volkswagen has drastically altered the vehicle’s structure and body. In fact, its wheelbase is 37 mm longer than the standard T-Roc while its overall length is up by 34 mm. In addition, the Volkswagen T-Roc Cabriolet features structural strengthening in the underbody, side panels, cross members, doors, and windscreen frame to make up for the lack of a roof. The folding fabric roof developed by Volkswagen retracts in just nine seconds at speeds of up to 19 mph (30.5 km/h) and is similar in operation to the roof of the outgoing Golf Cabriolet. The presence of the soft top reduces trunk space by 161 liters down from the 284 liters of the run-of-the-mill T-Roc. We don’t think bu...

Alpine A110 Hits Geneva With Pure, Legende And GT4 Versions

Image
Renault’s reborn Alpine brand has been getting rave reviews for its new A110 and now, as promised, it’s revealed new versions of its coupe at the Geneva Motor Show. Following the success of the sold-out Premiere Edition, the A110 will now be offered in Pure and Legende trims. The A110 Pure is targeted at driving enthusiasts. It features one-piece Sabelt sports seats that weigh barely more than 13 kilograms (28.6 pounds) each and, combined with other weight-saving measures, helps keep the curb weight below 1,100 kg ( 2,425 lbs). It’s not entirely stripped out, though, and still comes with features like air-conditioning and satellite navigation. Buyers can also add upgraded Brembo brakes and an adaptive exhaust system and can upgrade to the adjustable comfort seats. Those come standard on the Legende model, which is geared more towards every day driving and grand touring and comes with leather upholstery. Customers can also choose between two Focal sound systems and two wheel...
