What are the key changes under the skin of the 2012 Exige S?
There’s a faster steering rack, dropping the ratio from 18.5:1 to 17.25:1. The rack isn’t new, the ratio change instead coming from a shorter effective lever ratio. Combined with a wider front track, this has also created more steering lock, making it easier to hold powerslides. Now, this sounds childish, but it’s actually very important, because the old car ran out of steering angle perilously close to the point at which you naturally balanced the car during a slide, namely 32 degrees. This now rises to 35 degrees, reducing the potential of hitting the lockstops and thereby reducing the risk of the car spinning. You can genuinely feel the flexibility this brings when you play around on a racetrack.
There’s also a wider rear track, an entirely new rear subframe, plus revised springs and dampers all round. Meanwhile, Lotus has built an anti-squat angle into the suspension wishbone, helping to prevent, yes, squat under acceleration, and the lateral stiffness of the rear of the Exige increases by 100%, ensuring the car rolls along its centre-line through corners, where the old Exige could roll diagonally as the structure flexed. All this creates a virtuous circle. ‘Previously all the roll control was done by the springs and dampers,’ says chassis guru Matt Becker, ‘so they were stiffer than we’d have liked. And the extra lateral stiffness has allowed us to introduce an anti-roll bar. The old car wouldn’t have coped with the faster steering and the anti-roll bar – the rear axle would have always given up first.’
