PORSCHE 918 SPYDER


PORSCHE 918 SPYDER
Like the McLaren P1, the Porsche 918 Spyder uses lightweight efficiency along with brute power and aerodynamic refinement to get up to 322 kilometres (200 miles) per hour with ease. The drivetrain and other components weighing over 50 kilograms (110 pounds) in the plug-in hybrid are kept as low and central as possible to improve the centre of gravity and aid handling at speed. The exhaust pipes are also placed high up above the engine, for mechanical reasons rather than aerodynamics; the exhaust is occupying the already hot space above the engine, keeping the space underneath the engine cool enough to mount electric batteries.

Meanwhile, a carbon monocoque chassis means that the main part of the car is Light weight, while flaps underneath the head lights open to aid cooling of internal components and close at higher speeds to reduce drag.

RIMAC CONCEPT ONE
Although many hypercars use hybrid technology to cut down emissions, the Rimac Concept One is the first to be fully electric, eliminating the boundaries set by combustion engines including rev limits and turbo lag. Instead of a traditional combustion engine, this car’s powertrain is divided up into four electrical subsystems consisting of a motor, inverter and reduction gearbox, with each subsystem powering one wheel independently. Even better, the 92-kilowatt battery has a decent range too, powering the hypercar for up to 600 kilometres (373 miles) of driving with no environment harming emissions.
