While the Cup 380 was limited to 60 models, costing £83,000 each, the Cup 430 is a full production model and is priced from £99,800.
Using a development of the 3.5-litre V6 powertrain used in the Lotus Evora GT430, the Exige Cup 430 makes 430bhp at 7,000rpm and 325lb ft of torque from 4000rpm. It achieves 0-60mph in 3.2sec, which is 0.2sec faster than the Cup 380. That means a 55bhp hike in power over the Cup 380.
The Exige Cup 430 weighs just 1056kg in its lightest configuration, which is near-identical to the Cup 380. However, thanks to the extra power, the power-to-weight ratio is improved from 350bhp per tonne in the Cup 380 to 407bhp per tonne in this new model. Downforce is 220kg.
Lotus said that the powertrain paired with a newly designed body “delivers enhanced aerodynamic performance to reveal the model’s true potential”.
New aerodynamic features include an ultra-lightweight front clam panel with carbonfibre ducts and wider radiator apertures, plus a new mesh pattern grille to allow for a new front splitter and air curtain to reduce drag.
The lightweight rear clam panel supports the large, straight motorsport wing to increase downforce without impacting upon the car’s overall drag coefficient, Lotus says.
The new front and rear clam panels are 6.8kg lighter than those on any other Exige.
The Cup 430 is fitted with forged, four-position AP Racing brake calipers and new performance two-piece J-hook brake discs that are claimed to "give improved bite and deliver consistent pedal feel and stopping power lap after lap".
The Cup 430 also gets a steel roll-over bar, a new seatbelt anchorage frame and a front towing eye as standard. Options include a dealer-fit FIA-compliant roll cage, electric cut-off and fire extinguisher controls and a non-airbag steering wheel.
Lotus boss Jean-Marc Gales said: “This is the car that we have always wanted to build, and I am sure that all Lotus enthusiasts will be delighted with the end product.
“As well as a significant power hike, the Cup 430 has benefited from extensive development in areas essential to Lotus’ DNA, in order to ensure that the full potential of the Exige’s incredible chassis can be exploited. This car has no rivals – inside or outside of its price bracket - and it’s no exaggeration when we say that nothing can keep up with this Exige on the road or track.”
Lotus says the Exige Cup 430 has lapped its Hethel circuit in 1 minute 24.8 seconds, the fastest time yet for a production car and 1.2sec faster than the Lotus 3-Eleven Road.
