Lotus

The Lotus Carlton was a Vauxhall saloon rebuilt by Lotus around a twin-turbo straight-six, 377bhp, 176mph, faster than contemporary Ferraris with five seats, and so quick the press and Parliament called for it to be banned. A guide to how it was built, the ban campaign, the famous crime spree, what to check, and what one costs now.

The Lotus Elan paired a steel backbone chassis with a glassfibre body and the twin-cam engine, weighed barely 700 kilograms, and redefined sports-car handling for good. A guide to the S1 to Sprint, the +2 four-seater, the Emma Peel fame, what to check on chassis and twin-cam, and what an Elan costs today.

The Lotus Eleven was Colin Chapman's 1950s masterpiece, a featherweight, aerodynamic sports racer that took class honours at Le Mans and turned Lotus from a specials builder into a marque. A guide to the Eleven's engineering, its Le Mans record, Series 1 and 2, the replica question, and what genuine cars are worth.

The Lotus Esprit wore Giugiaro's sharpest wedge over a backbone chassis, drove underwater in The Spy Who Loved Me, and matured through turbocharging into a genuine supercar rival. A guide to the Giugiaro and Stevens eras, the Bond fame, the Turbo, what to check when buying, and what an Esprit costs today.

The Lotus Excel took the Elite and Eclat's wedge four-seater idea and rebuilt it with Toyota running gear into the most usable classic Lotus of all, then depreciated into the marque's great bargain. A guide to the Excel and the Eclat before it, the Toyota partnership, what to check when buying, and why it costs so little.

Lotus built Britain's cleverest sports cars from a philosophy Colin Chapman put in one line, simplify, then add lightness, and won seven Formula One constructors' titles while doing it. A guide to the classic Lotus road cars we cover, from the Eleven and Elan to the Esprit, Excel and the outrageous Lotus Carlton, what each is like to own and what they are worth.
