Toyota has brought its hybrid technology to the B segment with the world debut of the Yaris HSD Concept (Hybrid Synergy Drive) at the Geneva motor show, marking an important step in the company's strategy of rolling out hybrid technology across its European model line-up.
That programme began in 2010 with the launch of the Auris hybrid and, when the Yaris hybrids goes into production in 2012 it will introduce the technology to the “supermini” segment - the biggest in the European new-car market.
Toyota says the current growth of the B segment is one aspect of a shift in public demand. Customers are becoming less brand-loyal, more open to products outside the mainstream and more receptive to new technologies.
There is also a significant increase in the number of customers who are making engine type their primary consideration. Hybrids, it believes, are now seen as a clear alternative to diesel or petrol engines.
In fact, Auris hybrid owners say the best things about their cars are relaxation, an engaging driving experience and learning new driving habits.
The Yaris hybrid concept takes this model's design one step further with a shallow upper grille and highly contoured headlights, for smoother airflow over the upper body, and a long, sweeping roofline above a single, crisp character line running the length of the vehicle. Short front and rear overhangs and a long wheelbase maximise the room inside for passengers and luggage.
Flat, vertical “aero” corners minimise air turbulence and house front foglights, and matching rear reflectors. Airflow is also managed by a large, integral rear spoiler, underbody covers and 18” earo rims with big gaps to promote cooling.
The concept is finished in a special version of Toyota's special-for-hybrids pearl white with sparkling blue metallic accents, and trimmed with hybrid blue Toyota badging, LED daytime running lights and “synergy” blue illumination of the rear-view camera housings and door handles.
The roof is entirely covered with solar panels that power the aircon - after all, you only need it when the sun is shining.
Toyota's hybrid drive is designed for low maintenance; it has no starter motor or alternator, the timing chain is maintenance-free and there are no drive belts. But it will have to be specially tailored to fit into the very compact architecture of the Yaris without compromising passenger accommodation and load space, something Toyota admits will present engineering challenges.
The production Yaris hybrid will built at Valenciennes in Fvrance and will be released in Europe in the second half of 2012. The Auris hybrid is already being built at Burnaston in the UK, so Toyota will become only automaker producing hybrid vehicles at more than one European factory.
