Beneath styling inspired by Alfa's 8C Competizione supercar sits a reworked Punto/Corsa platform. As with other Mitos, the Cloverleaf is front-wheel drive and rides on MacPherson struts at the front and a torsion beam at the back. Even the Cloverleaf’s 1.4-litre turbocharged four-cylinder 16-value engine is basically the same unit that powers all petrol Mitos.
However, much has changed in the details. The most interesting is Multiair, in essence a form of variable valve timing working on the inlet. The difference with Multiair is that the system is electro-hydraulic, rather than purely mechanical, which allows for far greater control. Whereas most conventional variable valve timing systems switch between two settings, Multiair has five, one of which opens and closes the inlet valves twice in a single cycle. It can also operate different strategies on a cylinder-by-cylinder basis.
The result, says Alfa, is 12 percent more power, 11 percent less CO2 and a 10 percent drop in fuel consumption for the Multiair 135 (which replaces the TB120). For the Cloverleaf, which replaces the TB155, read 10 percent more power, nine per cent less CO2 and an eight per cent fall in consumption. Multiair-equipped Mitos also benefit from stop-start technology.
