New Formula One rule changes could lead to new controls in our cars.
The Formula 1 season is well underway and fast approaching the British Grand Prix this weekend.
Jenson Button is leading the way as Brawn GP have taken to the new rules better than most others. One of the new rules and for the first time in over 40 years drivers can now alter their aerodynamics during the race.
F1 drivers are permitted to change the aerodynamic characteristics of the car while it’s moving, significantly boosting their chances of overtaking. The new rule allows for a small but significant six-degree movement in adjustable flaps on the vehicle’s front wing, up to twice per lap; increasing downforce to combat the 'upwash' in a rival car’s wake, before cutting drag at the crucial moment for a sudden burst of speed.
To cause the effect on the flaps engineers need to us low weight motors with high torque to push the flaps whilst under strong force. To make this change, top engineers have used Neodymium magnet-equipped motors.
The miniature motors deliver immense low-speed torque for their weight and size, enabling teams to gain excellent results from the wing actuator using the smallest possible device.
Porsche and many other manufacturers already use variable spoilers to assist braking and to increase down-force when travelling at high speeds. It may not be long before we see the magnetic motors in top end sports cars on your high street.

There are many practical reasons to leasing a car rather than buying one. Car leasing offers lower monthly payments, lower initial deposit, road tax and breakdown recovery. You also have the opportunity to drive a new car every two or three years and all vehicles include the standard manufacturer’s warranty.
Our leasing deals are powered by Nationwide Vehicle Contracts.
