The Auris 2010 powertrain line-up features a choice of full, and three petrol and three diesel engines offering the performance- and economy-enhancing benefits of Toyota Optimal Drive. The introduction of a Hybrid Synergy Drive® model in the second half of 2010 will make this the most comprehensive range of powertrains available in the C segment, catering for every customer requirement.

Exclusively designed for the European market, the Auris HSD brings full hybrid technology to a core model at the heart of the Toyota line-up, the first step in the deployment of Hybrid Synergy Drive® across the company's entire European model range by the end of the decade.

The Auris HSD's full hybrid powertrain combines a 1.8 litre, VVT-i petrol engine and a 60 kW electric motor powered by a 27 kW Nickel-metal hydride battery, generating a total system power output of 136 DIN hp and offering performance to match any conventional 2.0 litre diesel hatchback. Conversely, the Auris HSD will return less than 99 g/km CO2 emissions and significantly lower NOx emissions than diesel engined cars of comparable performance.

Moreover, when operating in a unique, switchable EV mode unavailable to drivers of mild hybrid vehicles, the Auris HSD offers zero CO2 and NOx emissions, driving for up to two kilometres at speeds of up to 50 km/h.

The new Auris HSD easily meets Euro 5 emissions standards, and is expected to meet those of Euro 6. The Toyota full hybrid's ultra-low CO2 emissions offer customers significant tax incentives in several European countries.

Toyota Optimal Drive

Toyota Optimal Drive showcases a combination of wide-ranging advanced technologies and internal improvement programmes designed to optimise the balance of performance and driving enjoyment with fuel economy and low emissions.

These diverse core technologies focus on three key aspects of powertrain development:

— Firstly, the reduction of powertrain weight through the use of super-lightweight and highly compact engine components and transmissions throughout the Auris engine range.

— Secondly, the minimisation of mechanical losses through the adoption of Valvematic -a further development of VVT-i -in both the 1.6 and 1.8 litre petrol engines, new roller rocker technology and smaller, lighter pistons in all three petrol engines, low viscosity oil and new 6-speed manual transmissions throughout the Auris engine range, and an optional MultiMode transmission for the 1.6 litre petrol and

1.4l D-4D engines.

— Thirdly, the maximisation of combustion efficiency. This has been achieved within the Auris petrol engine range through the adoption of high, 11.5:1 compression ratios, Valvematic, the refinement of intake port and combustion chamber design, and the introduction of piston cooling by oil jet. All Auris diesel engines benefit from a lower compression ratio, optimised combustion chamber dimensions, enhanced Exhaust Gas Recirculation (EGR) cooler efficiency and stainless steel exhaust manifolds with close-coupled Diesel particulate Filters (DPF).

As a result of Toyota Optimal Drive technology, the Auris will be the first Toyota to comply with Euro V emission standards across the entire European model range by January 2010 (1.4D-4D July).

The application of Toyota Optimal Drive across the Auris 2010 range has significantly reduced CO2 emissions. The overall Auris CO2 average has been reduced from 152 g/km in 2007 to 142 g/km in 2009. In 2011, which will be the first full year of revised Auris range sales, the figure will reduce further to just 125 g/km.

The Auris also plays a significant role in reducing Toyota's whole-fleet CO2 average which, having fallen by 16 g/km from 2008 to 2009, already stands at just 130 g/km.

1.33l Dual VVT-i

Featuring innovative Stop & Start technology, the 1.33 litre petrol engine is equipped with Dual Variable Valve Timing-intelligent (VVT-i) and a remarkably high compression ratio of 11.5:1, which increases the thermal efficiency of the engine. It generates 73 kW/ 101 DIN hp and maximum torque of 128 Nm at 3800 rpm, the latter favourably comparable to rival 1.4 litre engines.

This excellent dynamic performance is combined with fuel consumption of 6.0 l/100 km and CO2 emissions of 139 g/km. When equipped with Stop & Start technology, the 1.33 litre unit's fuel consumption and CO2 emissions are lowered still further, to just 5.9 l/100 km and 136 g/km respectively.

Profiting from Toyota's extensive motorsport experience, the small bore, long stroke unit is exceptionally lightweight and compact, improving the vehicle's power-to-weight ratio. It features a resin-type cylinder head cover and intake manifold, and the intake channel has been streamlined to optimise airflow for improved combustion efficiency.

Dual VVT-i helps boost response levels across the entire rev range by varying the air-fuel intake and exhaust valve timing to suit the conditions at any given time. In addition to improving torque at low and medium engine speeds, the system also reduces emissions and enhances fuel efficiency.

In total, the advanced Toyota Optimal Drive innovations on the 1.33 litre engine have resulted in a huge, 17 % drop in fuel consumption compared to the Auris' previous 1.4 litre unit.

1.6l and 1.8l Valvematic petrol engines

Offering class-leading efficiency, power and torque, Valvematic is a further development of Toyota's highly successful Dual Variable Valve Timing-intelligent (Dual VVT-i) system.

Valvematic takes VVT-i technology a step forward by adding lift and duration control to the inlet valve variable timing. This improves intake airflow volume and speed management -and, subsequently, combustion process management- to deliver more power for less fuel consumption, with reduced CO2 emissions. The adoption of Valvematic further reduces friction and pumping losses under light engine loads, further lowering fuel consumption.

Valvematic efficiency is further improved through the adoption of a variable length inlet manifold. This acts as an accelerator at low to medium engine speeds, maximising inlet air speed for optimum combustion efficiency. At higher engine speeds the manifold is fully open. This allows air to travel via a shorter route, maximising the volume of air entering the combustion chamber and, hence, engine power output.

Available with either a six-speed manual or six-speed MultiMode transmission, the 1.6-litre Valvematic engine develops 132 DIN hp and class-leading maximum torque of 160 Nm at only 4,400 rpm. When equipped with the manual transmission the unit returns a combined cycle fuel consumption of 6.6 l/100 km and generates CO2 emissions of only 152 g/km. MultiMode transmission further reduces both fuel consumption and emissions, to 6.3 l/100 km and 146 g/km respectively.

Adding refined sportiness and a higher level of dynamism to the Auris range, the 1.8 litre Valvematic engine develops

147 DIN hp and maximum torque of 180Nm at 4,000 rpm. Equipped with a six-speed manual transmission, the engine's combined fuel consumption is only 6.7 l/100 km, and CO2 emissions are 155 g/km.

1.4l D-4D 90 diesel engine

Available with either a six-speed manual or six-speed MultiMode transmission, the 1.4 litre D-4D engine develops 90 DIN hp and maximum torque of 205 Nm at only 1,800 to 2,800 rpm, a torque output comparable to that of larger, 1.5 litre rival units. Both versions may be equipped with a Diesel Particulate Filter (DPF).

A DPF catalyst purifies hydrocarbons and carbon monoxide but also, simultaneously, reduces particulate matter. The particulate matter is trapped in the filter's substrate walls. The engine management system then burns off the soot so that the DPF is self-cleaning and requires no long-term maintenance.

The 1.4 D-4D 90 unit also benefits from Toyota Optimal Drive technology, maximising performance and driveability whilst minimising fuel consumption, and CO2 and particulate emissions.

New generation piezoelectric injectors control the fuel volume and the timing of the injection more accurately. The high speed reaction time of Piezo injectors makes multi-phase high speed injection possible. This has the effect of both lowering the rate of combustion expansion and effecting a more thorough burn within the combustion chamber, thus further reducing particulate, NOx and CO2 emissions.

This, allied to higher common rail injection pressures of

160 Mpa, results in shorter injection times, combining a faster engine response with improved fuel economy and CO2 emissions that are amongst the lowest in the C segment.

When equipped with the manual transmission and a Catalytic Converter (CCo), the 1.4 D-4D 90 unit returns a combined cycle fuel consumption of 4.7 l/100 km and generates CO2 emissions of only 124 g/km. Manual versions fitted with a DPF return just

4.5 l/100 km and a remarkable 118 g/km.

This outstanding, 118 g/km CO2 emissions performance has been achieved through combining the powertrain refinements of Toyota Optimal Drive with the adoption of various measures designed to maximise the aerodynamic and fuel efficiency of the Auris

1.4 D-4D 90, such as lowered suspension and low rolling resistance tyres.

So successfully has this been accomplished that the model's equipment specification has not been compromised, and customers still benefit from standard features including alloy wheels and single-zone air-conditioning.

Combined with a CCo, the 1.4 litre unit's MultiMode transmission returns 4.8 l/100 km and generates CO2 emissions of 127 g/km, whilst a combination of MultiMode and a DPF returns 4.9 l/100 km and lowers CO2 emissions to 129 g/km.

2.0l D-4D 125 diesel engine

Mated to a six-speed manual transmission and with a DPF fitted as standard, the 2.0 D-4D 125 benefits from all the Toyota Optimal Drive powertrain enhancements featured on the 1.4 D-4D 90. It delivers 127 DIN hp and maximum torque of 310 Nm from 1,800 to 2,400 rpm. Combined cycle fuel consumption is 5.2 l/100 km and CO2 emissions are 138 g/km.

2.2l D-4D 180 diesel engine

Also fitted with a six-speed manual transmission, the Auris' powerful, 2.2 litre turbodiesel further benefits from Toyota's Diesel-Clean Advanced Technology (Toyota D-CAT), which incorporates a Diesel Particulate and NOx Reduction filter (DPNR).

Operating in a similar fashion to a DPF, a DPNR further reduces particulate matter and NOx emissions to levels far below Euro 5 standards. An Exhaust Port Injector (EPI) injects fuel into the exhaust gas flow for secondary combustion in the catalyst chamber, minimising both NOx and particle matter emissions. A high-efficiency Exhaust Gas Recirculation cooler (EGR) reduces the temperature of combustion to further lower NOx emissions.

The 2.2 D-4D 180 unit delivers 177 DIN hp and a highly impressive maximum torque of 400 Nm between 2,000 and 2,800 rpm. Conversely, average fuel consumption is just 5.9 l/100 km, and CO2 emissions only 154 g/km.

MultiMode transmission

Available on 1.6 Valvematic petrol and 1.4 D-4D 90 diesel versions of the Auris 2010, MultiMode is an automated manual transmission with a fully automatic shift mode and no clutch pedal. It offers the driver a choice of two, fully automatic gear change modes or a manual, sequential gear change with steering wheel-mounted shift paddles.

Selecting E (Economy), M (Manual) or R (Reverse) allows the car to 'creep' in the manner of a conventional automatic. In E mode, the car makes automatic gear shifts that will maximise fuel economy. Selecting ES (Sport) mode will delay changing up to a higher rpm, giving a more sporting style of drive.

Stop & Start technology

Available with the 1.33 litre Dual VVT-i petrol engine, Toyota's Stop & Start system automatically switches off the engine when the vehicle is stopped. Featuring an immediate restart with virtually no engine sound or vibration, the system delivers significant reductions in CO2 emissions during urban driving, and can lower fuel consumption by up to 3 %, depending on driving conditions.

Stop & Start automatically stops the engine when the shift lever is moved to the neutral position and the clutch pedal is released, enhancing fuel economy. The engine will automatically restart, within less than half a second, when the clutch pedal is depressed.

Such a rapid restart is made possible through the use of the world's first permanently engaged gear mechanism in which the starter motor and the flywheel are linked, via a ring gear, by a one way clutch. This maintenance-free system not only eliminates the torque limitations of a belt-driven starter motor, but also reduces engine start noise levels within the cabin, and seat vibration levels.

Toyota Stop & Start technology allows for the continued operation of the air-conditioning system.

With the air-conditioning in use, the engine will not stop if the desired cabin temperature has not been reached. When that temperature is reached, the air-conditioner will switch to 'ECO-run loading', allowing the engine to automatically stop. The engine will automatically restart in the event of low battery charge, or if the vehicle begins to move, in the interest of safety.

In conjunction with the Stop & Start system, an 'ECO' indicator will illuminate during every automatic stop. An ECO counter also displays the elapsed time of stops during each drive, and a re-settable ECO odo-counter displays the vehicle's total accumulated idling stop time.

Gear shift indicator

A Gear Shift Indicator prompts the Auris driver to shift up or down a gear for maximum fuel efficiency. Monitoring driving conditions, vehicle speed and throttle inputs, the system can help reduce fuel consumption by 0.5-3.0 %, depending on driving styles.
