Lotus Exige S

The 79th International Geneva Motor Show sees the introduction of the exciting new 2010 Model Year Lotus Exige S with a newly designed front end, a new rear wing and impressive emissions of just 199 g/km CO2. The Lotus Exige is a renowned high performance coupe that has a well earned reputation of choice for drivers who demand uncompromised performance, both on the road and on the track.

Lotus has always pursued efficiency and fuel economy and for the 2010 Model Year Lotus Exige S, Lotus has reduced the emissions to only 199 g/km CO2 and increased the fuel economy to an impressive 8.5 litres/100 km on the Official European Combined Cycle and a frugal 6.5 litres/100 km on the Official European Extra Urban Cycle.

The 2010 Model Year also sees the introduction of a few key changes to the Exige to enhance the look and improve aerodynamic performance.

A restyled front end and new larger, rear wing that not only reduces drag, but also gives a more muscular stance enhancing the lightweight shrink-wrapped look of the whole car.

The composite rear wing is based on the design from the Exige GT3 road car concept shown at the Geneva Motorshow in 2007. Compared to the 2009 Model Year Exige tailgate mounted wing it is 181 mm wider and mounted 46 mm higher and 61 mm further back. It is attached to the rear bodyshell clam via rear end plates which not only increases the stiffness of the whole structure but also ensures that as much of the airflow as possible passes over the rear wing. This careful airflow management increases stability, reduces drag and, most importantly, maintains the impressive downforce figures of 42 kg at 160 km/h.

The restyled front end includes a larger, more angular air intake mouth to help funnel more air through the radiator, to improve the efficiency of the engine system. Ahead of the front wheels on either side of the main aperture, two larger air intakes increase the airflow to the twin oil coolers. Horizontal vanes bisect these oil cooler air-intakes to stabilise the airflow to further increase the cooling efficiency.

Since the Exige S2 was launched in 2004, the power has increased from 190 hp through 220 hp to 240 hp in standard road form more for the track centric Exige Cup 260 - and the new larger air intakes improve engine cooling for these current higher powered Exige variants.

Mounted below the three new air intakes is a new aerodynamic splitter for the 2010 Model Year Exige. Made from a lightweight composite, the splitter is now extended to wrap around the whole of the front end and chiseled side lips are raised to deflect air around the tyres to reduce drag.

Mike Kimberley, Chief Executive of Group Lotus plc said, Over the years, the Lotus Exige has developed a hardcore fan base around the world and its popularity has placed it as one of the legendary sportscars of the 21st century. So far, over 5000 Exiges have been hand-built at our high-tech manufacturing facility making it a significant contributor to our global production. The lightweight Exige has one of the highest specific power outputs of any globally emissions certified car and 133 hp per litre is a perfect demonstration of Colin Chapmans philosophy of performance through light weight and of Lotus' relentless pursuit of efficiency. The same technology that makes a lightweight car a high performer also makes it efficient how many cars have performance figures of 0 100 km/h in 4.77 secs but produce only 199 g/km CO2?

Like all Lotus cars, the functional components of the car are also beautifully designed as Russell Carr, Chief of Lotus Design, explains, For 2010 we have taken the already visually extreme Exige and given it even more visual drama. The changes we have integrated into the front and rear of the Exige signal an even clearer and purposeful intent. The purposeful rear wing is race inspired, the new angular air intakes and full width splitter gives a more hard-edged and aggressive look. Overall, the Exige appears more planted and gives the illusion that both the front and rear of the car are wider than they really are without losing its agile and lithe character.

Roger Becker, Director of Vehicle Engineering said, The changes we have made to the Exige for 2010 Model Year are quite subtle when taken individually, but taken as a complete package they make significant improvements to aerodynamics and the overall look of the car. The Exige is a classic fit-for-purpose performance machine, the design tweaks we have made have reduced the drag, cleaned up the airflow around the front and rear of the car, whilst retaining the impressive balanced downforce figures, to give an exciting high performance drive.

The specification of the highly successful 2009 Model Year Exige Cup 260, unveiled at the Paris Motorshow in 2008 remains unchanged.

With the Exige performance pack, the power is raised to 240 PS / 179 kW (minimum) at 8000 rpm courtesy of a Magnuson/Eaton M62 supercharger, new faster flowing injectors and higher torque clutch system and an upsized roof scoop to feed more air to the supercharger intercooler system.

This hike in power, together with an increase in torque to 170 lbft / 230 Nm / 23.5 kgm at 5,500 rpm from the standard 158.6 lbft / 215 Nm / 22 kgm at 5500 rpm, helps whisk the Performance Pack Exige S from zero to 60mph in 4.5 3 March 2009 Page 4 of 5 secs and 0-100km/h in 4.77 secs, and on to 100mph in 11.97 secs. Top speed rises to 145 mph. The power and torque of the 240 PS engine is increased across the rev range giving even more flexibility. Despite these high levels of performance the fuel economy is impressive with a new combined figure of 8.5 litres / 100 km and 199 g/km CO2 reduced from 9.1 litres / 100 km (combined) and 216 g/km CO2 for the 2009 Model Year Exige. Continuous engineering improvements over the last year including careful whole vehicle optimisation has enabled this sportscar to be even better for fuel economy and emissions.

Of course the increased power and straight-line performance are only a couple of elements of the Performance Pack option. The clutch is uprated and a clutch damper fitted; there are thicker, 308mm diameter cross-drilled and vented discs at the front clamped by AP Racing four-piston callipers; the standard brake pads are replaced by uprated pads.

Keen to pass on lessons learned on the track with the Exige GT3 racing programme, Lotus Sport has contributed another important track specific technology to the Performance Pack launch control combined with variable traction control.

From the drivers seat the track orientated launch control allows you to determine the engine revs you wish to use during a standing start on the track. Having programmed that limit, it will not be exceeded when you then hold down the throttle and sidestep the clutch at departure from the line. The clutch damper cushions the severity of the clutch / transmission engagement to minimise the stresses to the drivetrain (noting that continuous abusive standing start applications will destroy the drivetrain components). The launch control also keeps wheelspin at bay until 6 mph, after which the traction control assumes its duties.

As with launch control, you can dial in the amount of traction control you require from the drivers seats, altering it on the move to suit driving style and the characteristics of particular corners. The amount of traction control can be varied in over 30 increments from an optimum 7 percent tyre slip to completely off. The message display in the new instrument pack displays what degree of traction control you have currently dialled in.

The beauty of all the packs is that they can be combined so a customer can have the additional interior and exterior equipment from the Touring pack with the sport focussed equipment from the Sport pack.

Air conditioning, Lotus traction control and limited slip differential are available as stand-alone options.

Customers wanting to add further finishing touches to their Exige such as specifying adjustable dampers and forged wheels can do so by ordering from an extensive range of accessories.
