Porsche working on a new supercar with quad-turbocharged flat-eight engine to rival the Ferrari 458

Article by Christian A., on July 7, 2014

Porsche currently offers the 918 Spyder but it appears that the German manufacturer is working on a new V8-powered supercar to rival the Ferrari 458. Although there aren’t many details regarding the design of the new supercar, we expect it to be inspired by the 918 Spyder, with a long rear deck due to the fact that the vehicle will feature a mid-mounted flat eight engine.

Porsche is expected to work on a new 4.0-liter engine featuring a flat eight layout but what’s more interesting is that the manufacturer is currently testing the prototype engine with four turbos that will push the total output towards 600 hp.

For those who don’t know, the Ferrari 458 Italia is powered by a mid rear-mounted 4.5-liter V8 engine that generates 570 hp at 9,000 rpm and 540 Nm at 6,000 rpm. The German supercar is set to go on sale in 2017.

Still, Porsche is also working on a new family of turbocharged and normally-aspirated boxer engines that will be available in four, six and eight-cylinder formats. These engines will offer higher power densities and come with innovative fuel-saving technology.

A representation of the essence of the Porsche idea, the 918 Spyder combines pedigree motorsport technology and everyday usability as well as optimal performance and minimal consumption. Porsche is unveiling the new 918 Spyder at the 2013 Frankfurt Motor Show, thereby marking the beginning of a new saga for the hybrid drive.

This new flagship project is Porsche’s way to demonstrate the potential of the hybrid drive both in terms of performance and fuel efficiency, sans any compromise in any of these attributes. The parallel improvement in both performance and efficiency has been the guiding concept that allowed the Porsche 911 plug-in hybrid to become one of the most successful sports cars in the past half century. Now, the 918 Spyder provides the genetic blueprint for future Porsche sports cars.

It is apparent that the new Porsche 918 Spyder is heavily influenced by its connections to motorsport. In fact, the new 918 Spider employs a number of innovations made on Porsche’s race car for the 2014 edition of the 24 Hours of Le Mans, and vice versa. Its structural concept is derived from a rolling chassis -- a chassis without bodywork – just like Porsche’s race cars. Meanwhile, its V8 engine features a design derived from the mill of the RS Spyder, Porsche’s LMP2 (Le Mans Prototype 2) race car. Its supporting monocoque structures as well as unit carriers are made from (CFRP) carbon fiber reinforced plastic.

Interestingly, the Porsche 918 Spyder plug-in hybrid is significantly more fuel efficient than its rivals. It consumes around three liters of fuel per 100 kilometers (estimated NEDC fuel consumption), much less than the consumption of majority of current compact cars. This was achieved despite the Porsche 918 Spyder offering an output of more than 880 bhp, which is just as powerful as a race car. This means the Porsche 918 Spyder offers optimal driving pleasure and minimal fuel consumption.
