How quick? The 3-Eleven in race-spec can hit 60 MPH (96km/h) from rest in under three seconds, on its way to a top speed of 280km/h.
Thanks to a less-aggressive aero package the road-spec model has an even higher top speed, maxing-out at 290km/h.
In race-spec, the 3-Eleven weighs in at less than 900kg and is equipped with a six-speed sequential transmission with paddle-shifters, while the road-goer gets a six-speed manual H-pattern gearbox. Both versions get a Torsen limited-slip differential.
Power comes from Toyota’s 3.5 litre supercharged V6 as used in the Evora, but the output has been lifted to 336kW and 450Nm - a handy increase on the Evora's 257kW/400Nm figures.
The 3-Eleven sits on 18-inch alloy wheels up front and 19-inch at the rear wearing road- or track-focused Michelin tyres with AP Racing four-piston brake callipers housed within.
A Bosch anti-lock braking system is fitted, which Lotus has tuned for the track.
Like all other Lotuses, the body is a bonded and riveted aluminium monocoque hub chassis, with extra rigidity provided by a steel roll cage.
Lotus says the aluminium is 40 percent lighter than carbon-fibre, and the race-spec 3-Eleven will come with a six-point harness and additional support bars to satisfy FIA regulations.
Inside, the 3-Eleven gets a colour display screen which serves as the instrument cluster and can be switched between road and track modes, along a quick-release steering wheel. The track version gets a data logger, fire extinguisher and a battery kill switch.
Speaking at Goodwood, Lotus CEO Jean-Marc Gales warned would-be racers that the 3-Eleven is ‘so good’ that it isn’t suitable for everyone.
“We always say that to make a sports car better, you make it faster and lighter - the new Lotus 3-Eleven carries that philosophy to a new level, and is perfectly in keeping with our brand values,” Mr Gales said.
“This new car is a giant slayer, capable of embarrassing far more expensive rivals. It condenses our engineering know-how into one, hard-core package, and is so focused that it won’t suit everyone.
This is a perfect demonstration of the faster and lighter concept, something which will be crucial to all Lotus cars in the future.”
Lotus says only 311 3-Elevens (get it?) will be built, with prices for UK customers starting from £82,000 (AU$168,000) for the road-goer and £115,200 (AU$237,000) for the race-spec version.
Production is set to commence in February next year, but whether Australian customers will have the chance to purchase the 3-Eleven remains to be seen.
