What's it like?
A bit spartan inside. There are seats, harnesses, driving controls and a fire extinguisher, and that's about it. The track car gets an FIA-approved six-point harness and driver's seat. The road car gets a four-point harness and comfier seat – the same as for the passenger on both cars.
There is no windscreen, hood or doors. It is a spacious cabin though and there's a tinted Perspex aero-screen that could do with being a touch higher (you could get one of your kids to knock one up in CDT). It affords a view over the raised wings that's normally the reserved for the likes of McNish.
To drive, the 2-Eleven is absolutely brilliant. Lithe, agile, communicative and apocalyptically fast. Performance is as hilarious as you'd imagine. Any speed, any gear, it doesn't matter. The 2-Eleven's got an enormous powerband, huge performance and the rortiest exhuast I've heard in an Elise-based car.
On a track it's fantastic. Adams admits that a well-driven Radical might be quicker overall, but argues, reasonably, that's not just what this car is about. The 2-Eleven is approachable in a way a Lotus should be, and he's right.
The steering is exquisitely weighted (it's actually lighter at low speeds than an Elise's because of the reduced mass), it's responsive, communicative and as linear as they come.
Drive gently up to its limits and the 2-Eleven nudges into gentle understeer, but you can drive round it - trailing the brakes or lifting into a bend makes it neutral or induces mild, catchable oversteer.
I think the balance is about right, but if you'd rather the back always let go first, Launch Editions of the 2-Eleven get two-way adjustable Ohlins dampers and there's a tweakable front anti-roll bar.
The car comes with an electronic owner's manual that includes tips on how to set up the suspension, and even some recommended settings for different race tracks. There's an 18-step adjustable traction control system and a launch-control device.
And unlike some track specials, the 2-Eleven is really very usable on the road too. Lotus's factory is surrounded by brilliant B-roads and the 2-Eleven is just as fabulous on these as it is on the circuit.
As in most performance cars - especially those with 338bhp per tonne - you can't get close to the 2-Eleven's limits most of the time, but even stroking it along at 60 or 70 per cent is a joy. The steering's still wonderful and the engine's flexible. It even rides quite well.
Downsides? A few. Caterhams, which have a hood and a boot to the 2-Eleven's neither, are actually more practical.
And the Lotus isn't cheap. The track car is £39,995; the SVA-approved road car gets that comfier driver's seat, all the compulsories (lights, horn, etc) and an £1100 premium. And still has no roof. Enough to stop it being a five-star car? Not by a long chalk.
Should I buy one?
