Stop/start technology is now available on the Toyota Auris and the Smart ForTwo.
These systems automatically switch the vehicle’s engine off when stopped and in neutral with the clutch up – such as when waiting at traffic lights. As soon as the clutch is depressed again, the engine restarts.
That doesn’t sound much but it is said to have a dramatic effect on fuel economy and emissions.
Toyota calls its system ‘Stop&Start’, and it is fitted to the Auris in combination with an all-new 100bhp 1.33-litre petrol engine with a new six-speed gearbox.
Together with a series of drivetrain improvements, dubbed ‘Toyota Optimal Drive’, this Auris has fuel consumption of 48.7mpg combined, and CO2 emissions of 135g/km. These are 19% and 17% better than the existing 1.4-litre petrol Auris, respectively.
Smart’s system is called micro hybrid drive (‘mhd’), and is fitted as standard to all new 60bhp and 70bhp ForTwos. It improves fuel economy by ‘up to 24%’, and reduces CO2 emissions to 103g/km.
The introduction of mhd coincides with upgrades to the Smart’s interior – including new net storage pockets and a better LCD display – and some new exterior finishes.
The Toyota Auris Stop&Start is priced from £12,705, while a Smart with mhd costs from £7,060. Both are on sale now.
