Revealed: Mazda 3 MPS and stop-start
Full details of the car's performance figures will also be announced at the show, although it is likely to be powered by a turbocharged 2.3-litre petrol engine. Power is tipped to be around 270bhp.
The new Mazda 3 MPS is expected to go on sale in June, costing from around £19,000.
Mazda will also demonstrate its new engine stop-start system in Geneva.
The Mazda 3 i-stop will be linked to the 2.0-litre petrol engine, giving a 12% improvement in fuel economy. That should mean average fuel economy of around 40mpg and CO2 emissions of about 165g/km.
