Lotus has taken the wraps off the new Elise Cup 250.

Billed as the fastest road-going Elise ever created, the model replaces the Elise Cup 220 and features an aerodynamic styling package as well as lightweight 16- / 17-inch forged alloy wheels.  The car has also been equipped with a number of lightweight components including a lithium-ion battery and carbon fiber seats.

Customers who want to save even more weight can order a Carbon Aero Pack that replaces the standard front splitter, rear wing, rear diffuser, and side skirts with lightweight carbon fiber components. This reduces an additional 22 pounds of weight which brings the total down to 2,030 lbs.

The interior is relatively sparse but comes equipped with a leather-wrapped steering wheel, Alcantara upholstery, and a polished aluminum gear knob. Options include leather upholstery and a Clarion audio system with Bluetooth and iPod connectivity.

Power is provided by a supercharged 1.8-liter four-cylinder engine that has been tuned to produce 243 horsepower and 184 pound-feet of torque.  It is connected to a six-speed manual transmission which enables the car to accelerate from 0-60 miles per hour in 3.9 seconds before hitting a top speed of 154 mph.

Speaking of performance, Lotus says the car lapped the Hethel test track in 1 minute and 34 seconds.  This is four seconds faster than the Elise Cup 220 and represents the fastest recorded time for a production Elise.

Besides the upgraded engine, the model has been equipped with an adjustable front anti-roll bar, Bilstein dampers, Eibach coaxial coil springs, and a high-performance braking system.

The Lotus Elise Cup 250 will go on sale in April and pricing starts at £45,600 in the United Kingdom and €61,100 in Germany.
