Remember when the man behind the McLaren F1, Gordon Murray, revealed his plans for a new supercar? Called the T.50, the upcoming mid-engine road car is set to become the spiritual successor of the original F1 (whilst not being a McLaren) and it comes with a huge fan at the back and will be powered by a naturally-aspirated V12.

But what makes this supercar different from the rest? According to the man himself, the T.50 will work on the principle of 'weight-to-power'. Murray believes that unlike typical supercars that follow the power-to-weight ratio principle, the T.50 will adhere to a vehicle's 'weight-to-power' ratio. In the T.50, every 100 PS only has to propel 150 kg of the car whereas a typical supercar can only push 100 PS for every 210 kg of the car's weight.

By eliminating unnecessary weight, Murray believes that this will help the company make the T.50 as fast (and as light) as possible. Every component that designed and engineered for the T.50 has been made to be lightweight in order to follow the strict weight-saving measures. The result is a claimed curb weight of 980 kg – making it lighter than most supercars, as well as a Toyota Vios.

With that curb weight, Murray says that a naturally-aspirated, 4.0-liter V12 will suffice for the T.50. Despite its small displacement, the engine follows a similar lightweight construction as the supercar itself. Through innovating engineering and help from Cosworth Powertrain engineers (yes that Cosworth), the twelve-cylinder engine cranks out 650 PS while only weighing in at less than 180 kg. This makes the engine 60 kg lighter than the McLaren F1 V12 and is now the lightest road-going V12 to date.

Apart from making the engine itself lightweight, every nut, bolt, and washer were also taken into account to be lighter than usual in order to maintain the car's overall curb weight down. Even the pedal box and the transmission itself are 300g and 10g lighter than a Formula One's respectively as a way to make the T.50's weight well below 1,000 kg.

Should the T.50 officially make its debut soon, it might change how future supercars might be designed and built for the foreseeable future. Heck, Murray's principle of 'weight-to-power' might also become the new standard.
