Lotus is cranking up the aggression index of its exhilarating Exige S for 2010 with a nose and tail tweaking that benefits both the appearance and the functionality of this superb-handling GT. Spotlighted in Geneva, the upcoming Exige S borrows several elements first seen on the Exige GT3 concept displayed at the Swiss show in 2007. Its new front fascia treatment pairs a larger central air intake that feeds more cooling air to the engine radiator with bigger outboard inlets that more effectively vent the car's dual oil coolers while a new wraparound lower splitter finishes the look. Out back, a dual-pylon composite rear wing replaces the original single-mount unit. Wider, taller and set further back on the deck, Lotus says it improves stability and cuts drag while maintaining the same level of downforce. No final decision as yet on powertrain specs for 2010 U.S. models that will arrive here in the fall. While the 220-horsepower four in the base Exige S is likely to carry, we're hoping the top-line model transitions from S240 to S 260 status by swapping its current 240-horse supercharged engine for the 257-hp unit used in the limited-production 2009 Exige S 260.
