RRP from £37,000
The F Sport is the IS to pick if you want the raciest-looking version. It gets lowered sports suspension to reduce the amount of lean you get in fast corners, and heated sports seats to hold you in place.
You also get speedometer and rev-counter dials that are inspired by the Lexus LFA hypercar. You also get aluminium pedals and 18-inch alloy wheels to complete the sporty look.
