Lotus GT racer to debut at Super GT Malaysia Round
The Lotus Exige GT will make its competition debut in 2 weeks, in the Super GT Series (former Japan GT).
It is just a 2 hour race so I suppose it has a good chance of finishing... Lotus GT to debut in Super GT race |

Good to see Lotus involved in top flight motorsport again! The Exige is a very nice looking car, I hope it does well!

Strange as it is, that colour suits that car! It says 3.0ltr V6 engine in the car, but doesn't say exactly which manufacturer made the engine, anybody know who it's by?

There's a thread about the details of this car, but you'll have to look it up... it was last used a couple of months ago I believe

It is a "GM" unit - so I would assume it has Opel Ecotec roots.

Interesting to see if they have overcome the Elise/Exige achillies heel in racing form in terms of engine positioning (the centre of gravity is really high as it is mounted above the gearbox which is transverse to the axle). The car is longer, but I am not sure it is long enough to mount the gearbox behind the engine and lower the engine in the car....

This should answer your question
http://www.gglotus.org/ggrace/exigesport/exige5.jpg http://www.gglotus.org/ggrace/exigesport/newexige.htm "Powertrain: Engine and Transmission A narrow angle V6, 2,998 cc Swindon Racing Engines tuned GM racing engine is mounted longitudinally in the Lotus Sport Exige. The naturally aspirated 32-valve engine produces 400 hp (296 kW or 405 PS) at 7,750 rpm and 294 lb.ft (398 Nm or 40.6 kgm) of torque at 6,500 rpm and has a maximum engine speed of 8,250 rpm. When the light weight of the Lotus Sport Exige is taken into consideration, the power to weight ratio is a phenomenal 470 hp / tonne (0.351 kW/kg or 476 PS/tonne). The engine itself weighs 157 kg. Breathing is via an F1-style airbox and air snorkel from the roof panel of the Sport Exige directly into the six carbon fibre air trumpets. The dry-sump engine, with a bore of 89.0 mm and stroke of 93.7 mm is water cooled and also uses an oil-water heat exchanger to efficiently cool the oil. The whole engine is controlled by a Motec M600 electronic engine management system fitted inside the cockpit. The power is transferred from the engine to the rear wheels via a single mass stepped flywheel, AP Racing twin-disc cerametallic race clutch and Hewland NLT sequential six-speed dog type transmission (with in-line shift mechanism). The gearbox itself is cooled through an oil-water heat exchanger. A limited slip differential (separate power and brake ramp angles) completes the powertrain package. " |
