The exclusive Sprint parts account for about 57 pounds of that loss. They include a lithium-ion battery, forged wheels, polycarbonate rear window, and carbon fiber for the seats, roll bar cover, engine cover, and access panel. Interestingly, the biggest savings come from the lithium-ion battery, which is roughly 20 pounds lighter than the normal battery. Lotus also includes the optional two-piece brake rotors and carbon fiber door sills to reach the 90 pound total.
This all translates to slightly quicker 0-60 mph times for Elise Sprint models over their Sport counterparts. Both the 1.6-liter 134-horsepower Sprint and 1.8-liter 217-horsepower Sprint 220 models complete the run to 60 mph a tenth of a second quicker than the equivalent Sport versions, with times of 5.9 and 4.1 seconds respectively. The weight loss also results in a price gain. For either Sprint model, you'll end up paying an extra £5,000, which is a bit over $6,100 at current exchange rates. Of course, the Elise isn't available in the US anyway, so it's a moot point.
