New Lotus Exige S

Breathtaking performance from the fastest accelerating Lotus ever to come off the production line
Summary
A small lightweight sportscar weighing just 935 kg (2057 lbs), powered by a 162.5 kW (218 hp, 221 PS) high revving supercharged engine, giving a zero to 100 km/h time of just 4.3 seconds (0 – 60 mph in 4.1 seconds). It comes straight off the production line and isn’t an “aftermarket special”.
-Is this the quickest ever real-world production car?
-It is certainly the quickest Lotus production car - so far!
The Lotus Exige S is the latest addition to the Exige range and is a real sportscar that redefines the term “Extreme Performance”. With 90.5 kW / litre (121.4 hp / litre, 123 PS / litre), it is one of most powerful production cars in the world for its engine size but most importantly it has full type approval for all the markets in which it will be sold. The Lotus Exige S is not a limited edition, nor is it an aftermarket special – it is manufactured from start to finish in the world leading and award winning Lotus Manufacturing facility at Hethel, Norfolk.
Because the basic car is so immensely strong but lightweight (935 kg, 2057 lbs), giving a power to weight ratio of 173.8 kW/tonne (233.2 hp/tonne, 236.4 PS/tonne), performance is phenomenal, with 100 km/h being reached from a standing start in 4.3 seconds (0 – 60 mph in 4.1 seconds) and 160 km/h (100 mph) being reached in 9.98 seconds (estimate) before topping out at 238 km/h (148 mph). Inspite of this phenomenal performance the fuel economy is impressive with an official combined figure of 9.1 litres / 100 km (31.0 mpg) - extra urban is an impressive 7.2 litres / 100 km (39.2 mpg). Lotus believes that there is no car on sale anywhere in the world that has such good performance combined with such good fuel economy! Not that many customers will be buying this car principally for its fuel economy!! Being a Lotus, straight-line performance is not the most important factor, but every day driving on normal roads, or around a circuit is. There are very few cars on sale today that can match the speed, agility and safety of the Exige S in both day to day and track or circuit driving.
However the Exige S is not just a track day warrior. It is a sportscar that would be at home on the back roads, freeways and autobahns, as well as on city streets. With an extremely "torquey" engine and the classic Lotus suspension set-up of soft compliant springs and firm controllable dampers, the driving experience is an uncanny combination of telepathic-like handling with a taught and comfortable ride. There is really no car that handles quite like a Lotus.
Clive Dopson, Managing Director of Lotus Cars says, “The Exige S represents the ultimate “extreme” production Lotus, with performance that trumps other supercars costing twice or even three times as much. That it does so with the fuel economy of a family hatchback, stands as a testament to the Lotus concept of performance through light weight. Its an unbeatable package and an unbeatable drive.”


The Lotus Exige S in more detail
The Driving Experience
For what is probably the quickest “real world” production car, the driving experience has to be pretty special. The lightweight composite seats with ProBax technology hug the driver and passenger giving the right amount of support and security to cope with acceleration, braking and cornering forces of well over 1 g. The steering wheel is a small off-centre leather clad unit (both the airbag wheel and the non-airbag wheel) and is set in just the right position for comfort, driver dexterity and feedback. The gear stick is located just 15 cm (6 inches) from the steering wheel for quick, accurate and safe gear changes and the lightweight steel and aluminium pedals are located in just the right position for heel and toeing. The Lotus Exige S doesn’t have a multitude of user adjustment to the wheel or seat position – Lotus believes that the driving position is pretty close to perfect anyway!
What does acceleration feel like in a Lotus Exige S? First of all the feeling of acceleration is mildly addictive. Few vehicles, aside from racing cars, motorbikes and extreme theme-park rides, can pull this amount of g-force under acceleration, braking and cornering. This gives a safe, but fun (even exhilarating) experience that you can only get from such a finely honed sportscar.
The Engine
The heart of the Exige S is a Roots-type supercharger and air to air intercooler attached to the tried and tested 4-cylinder, 1.8 litre 2ZZ-GE VVTL-i engine. Using a development of the supercharger and intercooler package developed first for the already legendary Lotus Sport Exige 240R, the Exige S has peak power of 162.5 kW (221 PS, 218 hp) at 7800 rpm, 215 Nm (158.6 lb ft) of torque at 5500 rpm (but 80% is produced at just over 2000 rpm). Maximum engine speed is 8000 rpm (8500 rpm transient for up to 2 seconds). 162.5 kW (218 hp, 221 PS) is the figure that has been achieved by Lotus Engineers whilst retaining full vehicle type approval for the markets in which it is sold.
A slightly redesigned air intake and roof scoop has been added to the Exige S to ensure that the air to air intercooler works as efficiently and effectively as possible in all climates and environments.
A single oval exhaust exits from the centre of the undertray.
Aerodynamics is the key
The Lotus Exige S uses the same aerodynamic package as the standard Exige. Like all Lotus cars, the Lotus Exige S isn’t all about straight-line performance.
The Lotus Exige S is one of the quickest cars on normal roads and also around a circuit. Key to this incredible performance is the aerodynamic package, which creates 41.2 kg (90.64 lbs) of downforce - 19.3 kg (42.46 lbs) at the front and 21.9 kg (48.18 lbs) at the rear - at 160 km/h (100 mph). This downforce ratio between front (47%) and rear (53%) is balanced and remains constant at the speeds of which the Exige S is capable.
• This class leading aerodynamic package is provided through the contribution of the following components:
• Completely flat underside of the car – provided by the elegantly simple, strong yet light weight extruded and bonded aluminium tub
• Anodised rear diffuser which helps promote the “Venturi effect” underneath the car
• Deep front splitter, which sits just 108 mm (4.3 inches) from the ground (giving just enough ramp angle clearance) whilst still maintaining the aerodynamic properties and, of course, the aggressive stance.
• Fixed rear wing that is set at the optimum 11.5 degree angle for the best compromise between downforce and drag.


The Legendary Chassis and Body
The Lotus Exige S is built around the revolutionary and award winning extruded and bonded aluminium tub, with a light weight steel rear subframe, as used in the Exige. The chassis tub itself weighs just 68 kg (150 lbs) and has a stiffness of 10,500 Nm per degree.
The body of the Lotus Exige S remains unchanged from the Exige, as it is already a winning formula that is both effective and stunning to look at.
However, the key body components of the rear wing, front splitter and side air intakes are body colour coded to differentiate it from its naturally aspirated cousin.
Closely Related to the Lotus Sport Exige GT3.
At the end of 2005, Lotus developed and built the Lotus Sport Exige GT3 to suit the new FIA GT3 sportscar championship regulations. Weighing in at just 750 kg and producing around 285 hp, the Lotus Sport Exige GT3 is suitable for this new power to weight ratio racing.
The Lotus Sport Exige GT3 also uses a Roots type supercharger, an air-to-air intercooler (both are race prepared) and the 1.8 2ZZ-GE VVTL-I engine. The base engine and supercharger system is identical in the Lotus Exige S.
So with the Exige S acting as the base, a competitive GT3 sportscar has been successfully developed!
