Toyota Optimal Drive is an entire range of new engines, design innovations and transmissions that is bringing in a step-change in fuel economy and emissions across the Toyota range. Here are just a few of the new innovations you'll find in Toyota Optimal Drive.

Toyota Optimal Drive is designed to save you money, and reduce your carbon footprint. And the best bit? There's no compromise in performance.

Specified with 1.33-litre VVT-i petrol Yaris, Auris and Urban Cruiser models, Stop & Start saves fuel and emissions in urban conditions by seamlessly stopping and restarting the engine at lights or in stationary traffic. This helps to boost combined fuel economy by up to 18 per cent.

Reduced weight, lower internal friction, optimised valve control and greater rigidity are just a few of the improvements present in Toyota Optimal Drive engines. These innovations are applied differently across each model, but every engine offers a significant boost in terms of fuel economy and emissions, without sacrifice in power.

The new 6-speed Manual transmission available with Yaris, Auris and Urban Cruiser is a showcase for Toyota Optimal Drive thinking. Its unique twin-shaft design makes changing gear easier and more satisfying, and the reduced size and number of components improves efficiency and torque capacity.

All Auris, Avensis and iQ models come equipped with gearshift timing indicators (manual transmission only), showing the optimum time for gear changes and in turn saving fuel and emissions.

Toyota Optimal Drive offers an unrivalled combination of fuel economy and lower CO2, saving you money without compromising performance. Take the Toyota Optimal Drive challenge by comparing a Toyota Optimal Drive car of your choice against its major competitors.
