Jaguar has already officially and unofficially shown us their initial prototypes of the all-new Jaguar F-Type sports car sporting a dual center-mounted exhaust pipe layout similar to the Porsche Boxster S. But these latest spy photos show something new. We can see a dual quad exhaust layout which suggest something more powerful lies beneath the hood.
Jaguar already confirmed the 2-seater roadster will be available with a 3.0-liter V6 supercharged engine in two power output levels: 380HP (279kW / 375bhp) with 460Nm (339lb-ft) and 340HP (250kW / 335bhp) with 450Nm (332lb-ft). Following speculative reports, it was later confirmed an even more powerful engine would be available in the form of a supercharged 5.0-liter V8 unit that is already used in the XFR, XJ, XKR and XKR-S. Power output of the existing unit varies from 510PS (375kW/503hp) to 550 PS (405 kW / 542 hp).
You can draw your own conclusions but perhaps there's a chance this prototype testing at the Nurburgring Nordschleife is the more powerful 5.0-liter equipped F-Type R.
The new F-Type roadster will be unveiled later this year followed by a market launch in the summer of 2013.
