Elise S Engine Details

Details have emerged on the engine set to power the new supercharged MY12 Elise S.

The document explains the improvements to the new Elise S over the previous generation 2ZZ-GE powered Elise SC, which combines the Toyota 2ZR-FE engine with the new Magnuson R900 Supercharger.

Compared to the Elise SC the new Elise S promises a smoother power delivery, a near 20% increase in peak torque and equal peak power thanks to an increased boost pressure (0.8 bar), while reducing fuel consumption and CO2 emissions and meeting Euro 5 emission regulations. To help achieve this the Magnuson R900 Supercharger integrates the Supercharger, Intercooler and intake Manifold in to a single compact unit, reduce size and weight, and fit in the the same space as the intake manifold of the 1ZR-FAE engine fitted in the Elise 1.6. The Intercooler is a Water to Air, or charge cooler, system – harking back to the days of the Esprit Turbo SE – which sees water pumped to a front mounted water cooler to prevent the heat-soak issues which the supercharged 2ZZ-GE engines could sometimes be affected by in warmer climates.

The supercharger also features a bypass system which is activated at idle and under light load to improve fuel economy and reduce noise.
