Small Capacity Forced Induction

It's a strange example, but if you look at the engine in the new McLaren MP4-123. It's a much smaller proposition than the 6ltr V12 they ised in the old McLaren Fl. Now McLaren are using a 3.8ltr V8 twin-turbo to get their 592bhp and 200riph top spsed. Similarly, the next model Focus ST will drop engine capacity size but a more efficient design will see both increased power and economy.

Essentially, turbochargers are the best way to get performance from small capacity engines and coupled together they offer tetter economy through fuel usage and weight than big capacity engines. This is obviously very good news for the tuning world.

They're alreacy on the market, they have zero errissions and things look promising The Ecotricity Nemesis in this very issue, 330bhp, 45Dlb/ft, and 170mph. The Tesla Roadster too; 283bhp, 0-60mph in 3.7sec and a 245 mile range. The beauty of electric powered motors is their near constant peak torque, meaning they're a good performance option. The biggest problem with electric motors is achieving the right mix be:ween performance and the distance they can covcr between chargcs. The other conccrn is over the source of the electricity used to charge these cars. If the power station is running on fossil fuels, then it kind of defeats the object, hence Ecotric ty having a range of wind farms across the UK As mentioned elsewhere in the feature on the Nemesis, electric cars have huge tuning potential too. so we could see a host of fast and fun e ectric performance cars.

Hybrid cars generally run a small petrol engine with an alternative fuel source in tandem. For tuning, there's still the internal combus:ion engine to play with, and there is no doubt potential to upgrade the electric side too. In the future the formula will flip, where fossil fuelled devices will serve only to boost the performance of an electric motor

Turbine powered cars have existed. Rover made some in the past and they have even competed in top level motorsport. but they're too slow responding and not very eccnomical. Micro turbines on the other hand look to have a real future. Although they can't power a car on their own, they are very small and petrol or d esel powered ones can generate additional electricity that can be used to boost the performance

Below It'snot small, but 3.8ltr istiny fora 200mph supercar engine or range of an electric motor. It's realty a hybrid technology, with companies like Jaguar experimenting with it. But it helps to solve the major issue with electric cers. while dramatically decreasing the amount of traditional fuel needed.
