THE CATERHAM 420

Some cars just aren’t afraid of any road that comes into view.

But this bruiser is equally at home as a cruiser. The easy power delivery from the 2.0 litre engine, makes this the benevolent heavyweight of Sevens. Welcoming and fun to its friends, devastating to its rivals.

The Seven 420 is one of those cars. A 210bhp wielding gladiator ready to take on any highway one-on-one, the Seven 420 delivers huge dollops of torque, backed up by a high-revving, dry-sumped engine that makes it a wild, but intensely visceral ride.

Meanwhile, as the driver, you don’t need to be Ben Hur to tame this beast – the intuitive driving characteristics of the Seven mean this is one lion that can just as easily be a pussy cat at more sensible speeds.
