Porsche Cayman

With the next-generation Porsche Cayman caught running 'round the 'Ring, the reports/rumors about its platform and powertrains have begun to surface.

According to Car, both the Boxster and Cayman will ride on a wheelbase that's 60mm longer than its predecessor (up to 2,415 mm), with the overall length growing slightly and curb weight dropping by around 30 pounds. So nothing revelatory then...

However, Car contends that the next major Boxster/Cayman facelift is due around 2015/2016 and a host of new drivetrains will follow suit. A bigger bore twin-turbocharged 2.5-liter flat-four will replace the current 3.4-liter flat-six, developing over 350 horsepower and a similar amount of torque. A smaller, 1.6-liter version will make its way into the oft-rumored 356-inspired speedster, the nearly forgotten mid-engine Volkswagen and Audi's sub-TT. And don't be surprised if a hybrid-assist option appears in late 2016.

But for the time being, the current flat-six will soldier on, although we've heard that the four-pot could debut inside the Boxster at first, with the Cayman getting the new turbocharged mill the following year.
