Set to adopt a considerably different exterior and interior design.

McLaren launched the 650S Coupe a little over two years ago, but the Woking-based supercar marque is already gearing up for its replacement. Codenamed “P14,” the new model will use an evolution of the biturbo 3.8-liter V8 engine which develops 650 PS (641 hp / 478 kW) and 500 pound-feet (678 newton meters) of torque in the 650S. While some are saying the model’s name will start with “7” (so at least 700 hp), a McLaren spokesman has said it’s unlikely to happen.

According to company CEO Mike Flewitt, the 650S replacement will stick with the MonoCell carbon fiber chassis, but there are going to be some improvements for the new model. Now that the 570S is on sale, McLaren wants to keep a safe distance between its entry-level Sports Series and the mid-tier Super Series. That’s why the 650S successor is being developed to be considerably faster than the current car which runs to 62 mph (100 kph) in three seconds and maxes out at 207 mph (333 kph).

To do that, the “P14” will take advantage of active aerodynamics applied on a body which will have a considerably different design. Frank Stephenson, the man in charge of McLaren’s styling department, has promised the design will represent a “big leap” and the interior cabin will also be significantly changed.

In related news, it is believed McLaren is preparing a new downsized six-cylinder engine based on the existing V8 as a way to meet stricter emissions targets. While not confirmed by the company, Flewitt did say the number of cylinders will be reduced with time and during the transition from combustion engines to pure electric powertrains there are going to be hybrids.

Flewitt went on to specify today’s weight penalty for a hybrid stands at 66-110 lbs (30-50 kg), but the goal is to reduce it to zero and ultimately develop a hybrid powertrain lighter than a combustion engine.
