The Project NEF engine aims to produce a high performance prototype engine without the need to resort to exotic materials or manufacturing technology, ensuring the transition from prototype to production with ease and speed. It was designed and developed by Lotus Engineering’s powertrain division.
The first in the engine family is the 3.0 litre supercharged DOHC 75 degree V6 engine found in the new Lotus APX prototype. The supercharged 3.0 litre V6 makes 300hp at 6250rpm and 360Nm of torque at 4500rpm. 80% of that 360Nm of torque (288Nm) is available from as low as 1500rpm. Acceleration should be very good. Pretty impressive stuff.
Other family models include a 2.2 litre and 3.0 litre normally aspirated versions, which compliment this supercharged one. They are all production feasible, but not planned for production, unless of course there is a customer who wants to buy it. Perhaps Proton would be one of the potential customers? Makes sense seriously.
The narrow 75 degree angle makes the engine compact. It also gives the engine better vibration characteristics, removing the need for a balance shaft and the extra cost and weight that comes with it. The engine is controlled by a 32-bit ECU capable of 200 million calculations a second.
