Lotus Exige GT3

(Reading time: 2 - 3 minutes)

Exige GT3

On the 2nd of December 2005 at the annual FIA GT Championship presentation ceremony in Monte Carlo in Monaco, a new Exige prototype was unveiled. This car was designed for one main reason, to enter in the FIA series. A series of races for race cars that have power to weight ratio equally, and also a direct lineage to their road car versions.
The Exige GT3 was developed by Lotus Sport, the auto itself is a single seater prototype and with the aid of the performance division engineered to a high spec from the original model.

A new car

It weighs only 750 kg, and strictly sticks to Colin Chapman's philosophy of "performance through light weight". It utilises a race prepared 1.8 2ZZ-GE VVTL-i engine and a Roots supercharger with an air to air intercooler which uses the Lotus T4e ECU to produce 285 bhp @ 7,800 rpm. This creates a power to weight ratio of 380 bhp / tonne or 2.6 kg / PS.
Like the standard Lotus Exige, the GT3 is kitted out with the award-winning light weight aluminium bonded chassis, as well as light weight 5-spoke forged alloys, carbon panels, revised high downforce aerodynamics with added race front splitter and adjustable rear wing made from Carbon fibre. The car even has FIA approved 6-point roll cage, ignition kill switches, uprated suspension & brakes and with 3-way adjustable Öhlins dampers. and the whole thing is complimented by Lotus sequential 6 speed gearbox, and data logging system.

Lotus Esprit


Since the release of the 1st Lotus Esprit in 1976 till present day and the release of the new model in 2008, the car has been an Icon worthy of Hollywood films and real car drivers.
Esprit (1976 - 1980)
The Lotus Esprit was first shown to the world in 1974 as as a car style project by famed Italian design studio Giugiaro Design. The show car was so successful, and received instant enquiries, that Lotus took the successor to the Europa into immediate production. The Esprit had a Glass-Fibre body, steel chassis with backbone and specifically engineered 907 multi-valve engine this was mounted in the middle, each wheel was fitted with independent suspension, a real trademark for the first Esprits.
Esprit Turbo (1981 - 1987)
The 2nd mark used a turbocharger utilising technology learnt from track racing and applied, this saw a power increase to 210 bhp from a 2.2 litre engine. The Turbo Esprit was uprated also with rear suspension & stronger chassis. The Lotus's styling was even enhanced a deeper front spoiler and taller rear spoiler, this enhanced the cars handling at higher speeds. The Esprit Turbo was now able to reach 0-60 mph in 6 secs and 150 mph Top speed. The power was increased to 215 bhp in 1986 with the addition of the Bosch K-Jetronic fuel injection used on such cars as the Golf GTI. The designer Burt Rutan was contracted by Lotus to make a prototype 2-seat ultralight car whilst Chapman developed a small lightweight engine. The project was never finished before Colin Chapmans death.

Turbo (1988 - 1989)

The Lotus Esprit gave up its original lines of Giugiaro and was given a complete makeover including curved and softer lines. The Lotus esprit interior was also redone all the electrical system was completely overhauled with wiring, switches gauges and central locking. In 1989 the car was given an ECU with Delco base components. The original bhp was increased 228 bhp, even the 0-60 times were reduced to a quicker 5.2 secs the increase made the Lotus Esprit capable of reaching 155 mph. To handle the power increase a Renault built 5 speed gearbox was fitted. The Esprit SE came after with the overall power of the increased 280 bhp this was aided by a Lotus developed Chargecooler & enhanced ECU which utilises 6 fuel injectors. The Esprit SE was fitted with a deeper frontal air dam & rear wing. The 0-60 time fell to around 4.5 seconds and top speed around 165 mph. In 1991 three Esprit variations were produced, the standard Turbo SE, the Jim Clark Esprit version, and the X180R a street legal version of the racing car.
Esprit S4 & S4s (1994-1995)
The S4 was an iconic milestone for Lotus. The Exterior was changed new front and back bumpers, valances, new sidepods, rear wing mounted in the middle, and 17 inch rims were added.
The interior received a larger passenger area and airbag then power assisted steering increasing the Lotus cars refinements. In 1995 the Esprit S4 was added to with the intro of S4s. An aggressive looking car with sleek more aggresive rear wing providing the extra downforce needed. The turbocharger was uprated, this increased the S4s to 300 bhp, the car was given racing suspension shocks and springs. The car was capable of reaching 165 mph and 4.6 seconds 0-60 mph time.
Le Mans / Lotus GT1 Esprit (1996)
In 1996 a new version of the Esprit was unveiled on the Paul Richard racing circuit for the 1st race of the GT series, the GT1. It ran a V8 Lotus engine, a six-speed racing gearbox, Formula 1-style aerodynamics, carbon brakes, down to the min weight limit of 900 kg. The Esprit GT1 performed well, but was forced to retire due to a fractured exhaust.
1997 saw the release of the V8 a compact, light but powerful 3.5 litre V8 twin turbo charged. The car became the fastest road legal Esprit - 0 to 60 mph in just 4.1 seconds max speed 180 mph, the car adopted a new found supercar status.

Lotus Elise & Exige GT3

(Reading time: 3 - 5 minutes)

Lotus Elise & Exige GT3


The Lotus Elise was designed and manufactured to be a low amount production car, however the car regained the forefront of racing car production it completely shattered Lotus's expectations. Due to its fame many cool limited edition Lotus Elise cars have been developed and released, these include the 340R, Exige coupe, and several motorsport derivatives.
The Lotus Elise was initially shown as a windowless car running a 143 bhp K series Variable Valve Control engine similar to the MGF version. The benefit with VVC is it changes the cam profile progressively, however unlike the Honda VTEC engine which is similar but acts like an on/off switch. This unlike the Honda VTEC means power is available lower down the revs, this gave a wide & smooth power band. This was auto released as the Elise S1 111S in March 1999, this soon was replaced by a 160 bhp engine of the Sport 160 in August 2000.
Lotus Elise Mark II (2001)
The design was updated in 2001. Its smooth contours were replaced by aggressive angular styling. The Mk2 Elise was available in either a Sports Tourer or as the Race Tech model. 
The Sports Tourer came with full leather interior including, door panels & dashboard, factory fitted carpets and annodised aluminium fascia & controls, Lotus even fitted a quadrophonic eliseo speaker system, adjustable passenger footrest and cabin storage. The car was nicknamed the Lotus Monza in Hethel throughout its development.
The Race Tech version was more a racing car it featured a cockpit offering a racing inspired interior with ultra light in mind. Including carbon, leather and alcantara trim. The Race Tech came with more racing extras including Cross-grooved brake discs, auxiliary lights and aluminium controls and a two-speaker eliseo system.

Electric Elise

An Electric version of the Elise that runs solely on electricity, was made by Zytek Electric Vehicles Ltd. The car runs on two oil-cooled, internally mounted brushless DC motors. The power is transmitted to the wheels through Zytek custom gearboxes with the aid of Lotus drive shafts, this most likely drove the development of the Tesla Roadster.
Both motors weigh 26 kg combined they produce 100bhp with 550 Nm torque. The range is approx 120 miles urban driving, maxing out at approx 90 mph. The acceleration is 0-90 mph in 11.2 sec, the car only weighs in at 875 kg (with battery pack). A definite idea for the future.
The introduction of the Elise 111R in America
In January 2003 the US officially announced the Lotus Elise was to be made available, it was to be based on the Euro S3 version, but made to US legality standards.
It took till September 2003 when Lotus announced the engine to be used in the Elise would run a Toyota 2ZZ-GE 1.8 litre 4 cylinder 16-valve engine, this utilised VVT and Lift-Intelligent (VVTL-i) would be used in conjunction with a 6 speed gearbox, all specially tuned by Lotus specifically for the US markets. The auto would be capable of producing 190 bhp.
The American version of the Elise officially launched in LA at the 2004 Auto Show. The confirmation came that the car would weigh in at 891kg, 0-60mph in 4.8 secs and a max speed of 150 mph. The US Lotus came with a starter button as well as carpets and sound proofing higher capacity fuel tank, twin airbags, TRW anti-lock brakes with servo, air-con & climate control.
The car and engine were chosen in preperation to reduce launch issues if any and legal problems in the US by giving the choice to have the engine which was going to be utilised in the new Exige S2, at the Geneva motorshow in 2004.
This model became available in the UK in January 2004 under the name the Lotus Elise 111R.
