What is it?
Saying a new car is better than its predecessor is about as lazy as you can get because, if it weren’t, its maker would have had to have done something very wrong indeed.
But the Ariel Atom 4 is noteworthy because it’s better to such a huge extent over the outgoing Atom 3.5 that it’s like buying a brand-new smartphone and, within 15 minutes, wondering how you ever coped with the one you’d had for years. It’s like weighing up the relative merits of a Ferrari 488 GTB versus not just a 458 Italia but perhaps even an F430. It’s a seismic shift for the car from Somerset. And feels easily as rapid as a 488 GTB too.
Perhaps this shouldn’t be surprising given that the Atom 4 represents the biggest change to the Atom since the car was first launched at the turn of the century. It has been through plenty of iterations – some more significant than others – since then, but suspension pick-up points, uprights and geometry haven’t changed so much. This time, although it looks like an Atom, it’s new from the ground up.
Quite early in the process, Ariel’s designers and engineers decided that bigger chassis tubes (as possessed by Ariel’s experimental titanium chassis, although the Atom 4’s remain steel) were the way to go, not just from a strength perspective but also a visual one. Allied to wheel diameter an inch bigger front and rear, new geometry and updated bodywork, I’d say this is the first Atom with a really purposeful visual stance.
