2013 Toyota Yaris Hybrid Specs

Toyota is counting heavily on its new hybrid hatchback based on the new generation Yaris to boos the sales of its highly successful hybrid cars even further.

The new car features a highly sophisticated powertrain. The downsized hybrid system combines a substantially re-engineered 1.5 litre petrol engine with a lighter, more compact electric motor, transaxle, inverter and battery pack. The highly efficient powertrain offers the best balance of performance and fuel consumption/CO2 emissions in the B segment. It delivers an average fuel consumption of just 3.5 l/100 km and segment-best CO2 emissions of only 79 g/km, whilst allowing customers frequent, all-electric driving periods that emit no NOx, PM or CO2 emissions.

As for the economy, the Yaris hybrid offers fuel consumption of 3.1 l/100 km in the urban cycle, which is segment-busting. On top of all this, the car also looks nice. All things considered, it’s an A+.


Specs and details in the press release below:

The Toyota Yaris Hybrid differentiates itself from the other Yaris derivatives with an exclusive, aerodynamically efficient exterior design which instantly identifies it as the flagship of the Yaris model range.

It combines a new, more aggressive, Under Priority frontal design element – the distinctive new Toyota face design execution, with a Keen Look detailing reinforced by hybrid-specific LED lights.

Flanked by aerodynamically efficient front aero corner treatments, the strong centre section of the lower bumper houses a larger, trapezoidal lower grille optimising engine bay cooling whilst emphasise the new hybrid’s ground-hugging stance and low centre of gravity.

A slimmer upper grille, elegantly sculpted to highlight the hybrid-blue Toyota badge, is flanked by slim, Keen Look headlights which emphasise the new hybrid’s bold, horizontal front styling. Exclusive to the Toyota Yaris Hybrid, the projector-type headlamp unit features standard chrome-plated ‘eyebrows’ lipped with an LED ‘lightguide’, and LED Daytime Running Lights (DRL).

In profile, identified by hybrid badging and exclusive wheel designs, the new hybrid shares the stylish, cab-forward silhouette and long wheelbase profile of the standard Yaris. The exterior overall length is only 20 mm longer than the standard Yaris.

To the rear, the hybrid-blue badged tailgate incorporates a new, LED-type high mounted stop light, and clear lens combination lights incorporate a LED tail and stop lamp signature unique to the new Yaris Hybrid.

The Toyota Yaris Hybrid is available with a choice of unique 15″ and 16″ aerodynamic wheels, and a range of eight body colours including a model-specific new Pearl White finish execution.

Toyota pioneered this Pearl White finish, which has required the introduction of a bespoke production process at the TMMF plant where the new hybrid is built. Reinforcing the Toyota Yaris Hybrid’s uniquely stylish and environmentally-conscientious design credentials, the new colour delivers a cool, high quality image (particularly in sunlight) when the soft, silken lustre of pearl is at its strongest.

On board, Toyota Yaris Hybrid customers benefit from a driver-focused cockpit with hybrid-exclusive details and trim finishes.

Compact, Lower Displacement Petrol Engine

The 1,497 cc, 16 valve, DOHC Atkinson Cycle petrol engine with VVT-i is based on the engine block of the second generation Prius, but has been completely re-engineered. It is 50 mm shorter and 17 kg lighter than the 1.8 litre unit of existing Toyota full hybrid powertrains, equating to a 10% reduction in length and a 17% reduction in weight.

The new engine generates a maximum 55 kW/74 DIN hp at 4,800 rpm and maximum torque of 111 Nm from 3,600 to 4,400 rpm. With a focus on lower emissions and the minimisation of mechanical friction for improved fuel efficiency, some 70% of all engine components are either new or redesigned.

Overall, the thermal efficiency of the Toyota Yaris Hybrid petrol engine has been improved by 6% over that of the second generation Prius, contributing to improvements in both fuel efficiency and environmental performance.

Newly adopted engine technologies include a cooled Exhaust Gas Recirculation (EGR) system, an electric water pump, the elimination of the auxiliary drive belt, a low-friction timing chain, a lightweight, resin-based intake manifold and a compact exhaust manifold.

When used in combined with a cooled EGR system, the Atkinson cycle engine offers significant gains in fuel efficiency and the reduction of emissions.

In the Atkinson cycle, compression and expansion are asymmetrical, and the inlet valves close late, delaying compression. This creates a high expansion ratio for less compression, converting combustion energy to engine power more effectively. As a result, the exhaust temperature is lower than that of conventional engines. The cooled EGR system reintroduces cooled exhaust gas into the intake system, further reducing engine operating temperatures.

Allied to a small, lightweight, multi-function radiator, the adoption of an electric water pump both enhances engine warm-up performance and reduces cooling friction loss, improving fuel efficiency. The elimination of a mechanical pump drive belt reduces friction, further improving fuel economy.

A new, more compact, hybrid-exclusive resin-based intake manifold combines light weight with improved quietness through the reduction of both vibration and noise. And the use of highly efficient, 12-hole atomizing fuel injectors reduces both fuel consumption and emissions.

The exhaust system features a new, low heat capacity, maniverter-type exhaust manifold. By positioning the catalytic converter much closer to the engine exhaust port, it decreases the catalyser warm-up time by 24% and contributes to a marked improvement in emissions during shorter journeys.
