The McLaren Graziano gearbox is a compact, high-performance dual-clutch transaxle engineered to deliver rapid shifts, direct driver control and everyday usability. We examine how the seven-speed SSG operates, why McLaren selected it and what owners need to know about servicing, heat management and tuned vehicles.

Mechanical grip and aerodynamic grip are often discussed as separate qualities, but both ultimately depend on the tyres transmitting force to the road. Mechanical grip is governed mainly by tyre behaviour, suspension geometry, load transfer, alignment, damping and drivetrain control. Aerodynamic grip comes from downforce increasing tyre load as speed rises. This technical guide explains how both systems work, how they interact and why a fast car requires balance rather than s

Car wheels are available in steel, cast aluminium, flow-formed aluminium, forged aluminium, magnesium and carbon-fibre constructions. Each material and manufacturing process offers a different balance of weight, strength, stiffness, durability, cost and repairability. This guide explains how the principal wheel types are manufactured, their history and which designs are best suited to road, performance and motorsport use.

Tyres are the only components connecting a vehicle to the road, making them critical to acceleration, braking, steering and stability. This guide explains the main types of car tyres, how they are constructed, what their compounds contain and why road, performance, winter, off-road and racing tyres require very different designs.

A powerful engine makes a car fast, but a properly engineered braking system makes that performance usable. From traditional drum brakes and cast-iron discs to carbon-ceramic rotors, racing pads and regenerative braking, every system has been designed for a particular operating environment. This guide explains the main types of car brakes, brake discs, calipers and brake-pad compounds, including their advantages, disadvantages and correct applications.
