Following the introduction late
last year of the Toyota Optimal Drive 1.33-litre
Dual VVT-i engine with Stop & Start, Auris gains
the new 1.6-litre Valvematic engine and revised
versions of its established 1.4 and 2.0 D-4D and
2.2 D-CAT 180 units. The result is
cleaner, more fuel-efficient motoring with no
compromise in performance or driving pleasure,
plus significant savings in ownership costs
compared to its market rivals.
NEW 1.6-litre VALVEMATIC ENGINE
The new 1.6-litre Valvematic engine, built at Deeside in the UK, is expected to be the largest-selling unit in the 2009 Auris range. It benefits from Toyota Optimal Drive technologies, notably variable valve lift, enabling it to deliver more power and torque than the previous 1.6 VVT-i engine, while at the same time making significant improvements in fuel consumption and emissions levels.
The fuel economy delivered by both the 1.33 Dual VVT-i and 1.6 Valvematic petrol engines in Auris, combined with the per-litre cost of diesel fuel and the price premium of diesel models, make them a compelling choice for customers who traditionally might opt for diesel-powered cars on the grounds of running costs.
Power output from the engine is up by 8bhp (8 DIN hp) and maximum torque rises from 157Nm at 5,200rpm to 160Nm at 4,400rpm. It is available with either a new six-speed transmission, or new six-speed MultiMode system with paddle-shift controls. With the manual gearbox, CO2 emissions are down eight per cent at 153g/km and fuel consumption is improved by nine per cent in combined cycle driving at 43.5mpg. With MultiMode the reduction in emissions is 15g/km to 146g/km, while fuel economy rises by 4.7mpg – more than 11 per cent – to 45.6mpg (combined).
REVISED 1.4-litre AND 2.0-litre D-4D ENGINES
The 89bhp 1.4 D-4D diesel engine has been upgraded with Toyota Optimal Drive technology, with fuel economy increasing by six per cent to 60.1mpg in combined cycle driving (58.9 MultiMode). Carbon dioxide emissions have been reduced, falling from 132 to 125g/km for manual TR models, 127g/km for versions with MultiMode. At the same time, torque performance is stronger by eight per cent, rising to a maximum 205Nm between 1,800 and 2,800rpm.
As well as delivering CO2 emissions that are among the best in Auris’s segment, the engine is more responsive. This has been made possible by new piezo-electric injectors that control fuel volume and injection timing more accurately and give a shorter injection time.
The 2.0 D-4D engine in Auris gains a diesel particulate filter (DPF), which brings emissions performance in line with Euro V standards. It delivers 125bhp (126 DIN hp) and maximum torque of 310Nm between 1,800 and 2,400rpm via a six-speed manual transmission. CO2 emissions are reduced by 13g/km to 138g/km and fuel consumption is improved by 4.7mpg to 54.3mpg (combined cycle).
