What is a rally transmission?

Some rally cars use regular manual H-pattern gearboxes, while the others use sequential gearboxes, where gears are selected in orders, so the driver has only a lever which is pulled back to shift up and pushed forward to downshift. WRC rally cars use paddle-shift system on the wheel to react even faster.

Why do rally cars use sequential?

They provide the best of both worlds, providing smooth automatic operation in normal driving, and lightning-fast gear changes while going flat-out. But when it comes to actual racing, they’re still not the gearbox of choice. … The sequential also has fewer gear shafts to spin—just two versus three for the dual-clutch.

Why are sequential gearboxes so expensive?

The system is semi-automated to change gears faster than a normal car. The system uses a computer controlled servo valve for actuating gear changes and this makes the system costly.

Why do rally cars have small engines?

Even in grueling endurance races like the Dakar or Breslau, the vehicles often use turbos. I know that they are more economical, more powerful, allow the engine to be smaller, and can help offset any elevation gain so rally cars can be lighter, use less fuel, make more torque, etc.

Are rally cars 4WD or AWD?

Because modern WRC cars are all-wheel drive, they have a center differential that splits torque from the engine to the front and the rear.
