Jeremy Clarkson and Richard Hammond tackle the twin problems of an ageing population and the increasing complexity of modern cars. Their solution is to design a vehicle exclusively for the elderly and then test it out in Dorset with a little help from a trio of pensioners. James May assesses the new Range Rover around London and then shifts to Nevada for the ultimate challenge against an autonomous military machine. James McAvoy is the star in the Reasonably Priced Car.

Matt LeBlanc, Chris Harris and Rory Reid return for the 24th series of Top Gear. This week features the astonishing, ultra-exclusive Ferrari FXXK, tested to the max by Chris Harris at the Daytona circuit in Florida. Matt, Chris and Rory then race across Kazakhstan in three high-mileage cars: a Mercedes saloon, a Volvo estate and a London taxi, all of which have done at least 480,000 miles, the equivalent distance of going to the moon and back. Actor James McAvoy guest stars in the studio and on the famous Top Gear test track.
