Toyota Europe has published initial CO2 data for the forthcoming Yaris, which will introduce latest-generation hybrid technology when it launches this coming autumn.

The fourth-gen Yaris launches this autumn

Marking the first application of the Toyota New Global Architecture modular platform programme in a compact car – with the GA-B platform to also be used for a new compact SUV – the Yaris is shorter, wider and lower than the current model and uses intelligent packaging to maximise interior space, although figures are yet to be released.

As well as introducing a bolder design and higher-quality materials, including a Yaris-first of a soft-touch instrument panel, it also heralds the first use of the new TNGA three-cylinder, fourth-generation hybrid system.

The 1.5 Hybrid Dynamic Force system is directly derived from the larger 2.0- and 2.5-litre systems that were introduced in the new Corolla, RAV4 and Camry models, and features the new 1.5 Dynamic Force three-cylinder Atkinson cycle petrol engine with variable valve-timing. The new technology achieves a 40% thermal efficiency, higher than typical diesel engines, helping secure a more than 20% improvement in Yaris’ fuel economy and CO2 emissions; estimated figures put CO2 emissions at 64g/km NEDC Correlated (compared to 84g/km on the current model) and 86g/km WLTP, with combined WLTP fuel consumption of 3.7l/100km (76.3mpg).

At the same time, power output has been increased by 15%, giving a total 116hp, and the hybrid will offer an estimated 0-62mph time of 10.5 seconds (11.8 on current model).

The system also adopts a new, more powerful lithium-ion hybrid battery that’s also 27% lighter than the nickel-metal hydride battery it replaces.

The new Yaris will also be available with 1.5 and 1.0-litre three-cylinder petrol engines in selected markets. More details of these powertrains will be released at a later date.

Specifications are yet to be confirmed but technology will include a central Toyota Touch screen, a TFT multi-information display in the instrument binnacle and a 10-inch colour head-up display, which projects key driving data and warnings such as navigation prompts and speed limits onto the windscreen within the driver’s field of view. Other features on offer include a wireless charger designed to accommodate the latest generation of smartphones, a heated steering wheel and special ambient cabin lighting.

Advanced driver assistance systems include full speed-range intelligent adaptive cruise control and lane trace assist system as found on recently launched Toyota models such as Corolla. The Yaris is also claimed to be the first car in the compact segment to introduce a centre airbag.

The new Yaris will continue to be manufactured at the Toyota Motor Manufacturing France facility – alongside the forthcoming yet-to-be-named compact SUV – with full economy, pricing and specification data expected this summer.
