19. Jaguar XJ220©JLR
Jaguar’s 1998 XJ220 concept car promised four-wheel drive, a 6.2-litre dohc version of the TWR-developed V12 that had taken the XJR-9 to Le Mans glory earlier that year, and, of course, a 220mph top speed.
The production version Jaguar delivered four years later made do with a twin-turbocharged V6 and rear-wheel drive, though its verified 217mph maximum wasn’t far off.
