The fourth episode of Fifth Gear's new series will be on tonight, hitting our screens at 8PM.
To kick things off, Vicki will be performing a thoroughly scientific test of 'premium' petrol to see just what - if any - difference it makes to the power output of your car.
Meanwhile, Tiff is off taking part in the archetypal playboys' race series - where 'every car is a Lamborghini', and 'every driver is a millionaire'.
Finally, Jason will be driving the Toyota GT86 and – if the preview clip is anything to go by – subjecting it to a fair amount of sideways action too.
The much-loved motoring show started back in 2002, and has just celebrated its 10th birthday by upping sticks and moving to a new channel.
The current series began on September 3, and is available to watch on Discovery Channel UK – Sky channel 520, Virgin Media channel 212.
