New 1.4-Litre D-4D Engine
The new 1.4-litre D-4D engine is an improved version of the diesel engine featured in the Toyota Yaris range and it replaces the previous 89bhp 2.0-litre D-4D unit. It will be available from 1 September in hatchback and saloon versions of the new Corolla. As an option, it will be offered with Toyota’s Multi-mode Manual Transmission (MMT), which gives the driver the choice of fully automatic or quick sequential manual gear selection.
The new engine matches the previous 2.0-litre unit in terms of power output, yet achieves better fuel economy and exhaust emissions in line with Euro IV requirements. The new 1.4-litre D-4D engine develops its 89bhp at 3,800rpm, giving the Corolla a top speed of 112mph and nought to 62mph acceleration time of 13.3 seconds (14.5 for models with MMT). Fuel consumption on the European combined cycle is 57.6mpg (58.9 with MMT) and CO2 emissions are rated at 127g/km (125g/km MMT).
Multi-Mode Manual Transmission Improves Fuel Economy
The Multi-mode Manual Transmission is being offered for the first time on a Toyota diesel. The system, a £500 option, is unique in its segment, being a manual transmission, driven by electric motors. As it has an automatic clutch, there is no clutch pedal.
MMT operates in three different modes, according to driver choice: automatic in normal or sporty mode (E and Es) and manual, in which the driver selects the gears by means of a sequential shift lever.
In E mode, MMT can reduce fuel consumption and carbon dioxide emissions by about two per cent (in EC combined cycle driving), compared to the performance of a conventional manual transmission. This is possible thanks to system software that designs the gearshift pattern to benefit fuel economy.
When Es mode is selected, the transmission makes quicker gear changes at higher revs, in order to deliver a sportier drive.
Euro-IV Compliant Engine Range
The new 1.4-litre D-4D engine will join a range of petrol and diesel engines that already comply with Euro IV emissions standards. The 1.4 and 1.6-litre VVT-i petrol engines feature intelligent variable valve timing for stronger performance at all engine speeds with improved fuel economy and lower exhaust emissions. The 189bhp 1.8 VVTL-i engine, available only in the T Sport, is a high-performing unit that benefits from variable valve lift as well as timing. The 2.0-litre D-4D diesel engine, introduced in 2003, develops 114bhp and is exceptionally economical, capable of 49.6mpg in combined cycle driving.Published 19 June 2004
