Although high-tech, it represented affordable cost of ownership for sports car lovers on a budget who still wanted performance and looks. Besides the "standard" higher-performance variants listed below, Lotus also released some limited edition models such as Sport 135 (1998/9) with approx 145 bhp (108 kW), Sport 160 (2000) with 150160 bhp (112119 kW) and Sport 190 (190 bhp / 142 kW). These were more competent on track with sports suspension, wheels and tyres, seats according to model. There were other special editions which were basically cosmetic treatments such as the 50th Anniversary Edition (green/gold) celebrating 50 years of Lotus cars, the Type 49 ("Gold Leaf" red and white two-tone), and Type 72 ("JPS" black/gold) to recall their successful Grand Prix car type numbers.
The original Elise, called the Series 1 was augmented by a faster edition called the 111S, named after the Lotus type-number of the Elise M111. The 111S was introduced in early 1999 and contained a VVC Rover K-Series engine with a modified head and VVT type technology producing a declared 143 bhp (107 kW) rather than the standard Rover 1.8 L K-series 118 bhp (88 kW) unit, along with a closer ratio gearbox and lower ratio final drive. It also had more padding in the seats. The 111S also received some cosmetic changes including: headlamp covers, rear spoiler, cross drilled brake discs, alloy window winders and a new 6 spoke road wheel design.
The Series 2 Elise model comes in European 111R version or a version sold in North America, called the Federal Elise. It is powered by the all-aluminium 189 hp (141 kW) 1.8L DOHC Toyota engine with a Yamaha designed twin-cam head offering variable valve timing on both intake and exhaust valvetrain, a 6 speed manual Toyota gearbox. The Series 2 model is acclaimed as the best version of the Elise to date, with tremendous performance numbers, with many tests resulting in 060 mph (0100 km/h) in approximately 4.9 seconds or 4.7 seconds with the Sport Package. The engine management computer is a Lotus programmed unit. A radical cam timing shift at ~6,000 rpm makes the car feel like it has two different engines.Source: Wikipedia.
