Fuel economy improvements no matter the engine chosen. [xfloat=left]http://www.cleanmpg.com/photos/data/501/2009_European_Toyota_Yaris.jpg[/xfloat]Wayne Gerdes – CleanMPG – Jan. 19, 2009 European 2009 Toyota Yaris – Upgraded with the “Right Stuff.” The Yaris in Europe outsells the States by almost 2.5:1. Along with it being the company’s best-selling model in Europe, Yaris sales on the Continent have reached over 2.1 million units since initial launch. Hybrid technology has been playing an ever increasing role in Toyota’s European sales success but HSD has not had nearly the same success as the Yaris itself. Thus Toyota wants to also strengthen its position as a leader in conventional powertrain technology which brings us Optimal Drive. The concept is simple – enhance performance, while reducing fuel consumption. Toyota’s Optimal Drive improves combustion efficiency, lowers engine/transmission weight, and reduces friction to produce new engines that deliver more power yet, at the same time, are more fuel efficient. Improved 1.4L Turbo-Diesel The 1.4-litre D-4D diesel engine features latest generation common rail technology with an inter-cooled turbocharger. Integration of the latest common rail and piezo-electric technology along with a lower compression ratio allows high injection pressures for improved combustion efficiency and lower emissions. Other engine improvements include a water spacer jacket, serpentine auto tensioner, “in oil pan” oil pump, low viscosity oil and reduced belt tension. All-new 1.33L Engine The Yaris 2009 is available with a new 1.33L gasoline engine featuring “Start/Stop” technology. The new engine is fitted with state-of-the-art Dual VVT-i (Variable Valve Timing-intelligent) producing 101 HP and has the world’s highest compression ratio for a gasoline engine at 11.5:1. FE of 46.1 mpgUS combined on the NEDC with either of the tall geared 6-speed transmissions is the result. Improved 1.0L Engine The 1.0L, 3-cylinder power plant includes the following improvements: A newly developed fuel cut off system saves fuel during gear changes Improvements to the Electronic Fuel Injection (EFI) management Certified use of lower viscosity oil for less engine resistance Exhaust Gas Recirculation system and cylinder block water jacket spacer included In addition, low rolling resistance tires on the 1.0 and 1.33L Yaris’ contribute to the lower fuel consumption figures. New 6-Speed Transmission(s) As part of the Toyota Optimal Drive technology a new 6-speed transmission was developed for the 1.33-litre Dual VVT-I and 1.4-litre D-4D engines. This new transmission delivers world-class levels of transmission efficiency and improved fuel economy thanks to a tall 6th gear ratio. The 6-speed manual transmission also improves shift feeling using a new shift structure to offer a high level of quietness by optimizing gears and smooth clutch feeling. The Yaris 1.0L VVTi, 1.33-litre Dual VVT-i and 1.4-litre D-4D can be ordered with the latest 6-speed version of Toyota’s MultiMode system. This efficient new gearbox is an electrically-operated automated manual transmission, adopting two electric motors and an electronically-operated clutch to produce either automatic or sequential gear change. 2009 European Yaris basic performance specs and FE increase over predecessors Column1Column2Column3Column4Column5Engine size (L)*Transmission**FE (mpgUS)% increase in FE from previous gen.0 – 60 mph (seconds) 1.0 Gas6-speed MT47.0+ 9%15.5 1.0 Gas6-speed MMT48.0+ 10%16.7 1.33 Gas6-speed MT w/ Stop/Start46.1+ 21%11.5 1.33 Gas6-speed MMT w/out Stop/Start46.1+ 17 %13.2 1.4L D4D Diesel6-speed MT57.4+ 10%10.5 1.4L D4D Diesel6-speed MMT56.0+ 9%11.7 * MT: Manual Transmission, MMT: Automated Manual Transmission ** On the European NEDC test cycle(s) The only real question is when will the North American Yaris receive the powerful yet very fuel efficient 1.33L w/ the tall-geared 6-speed MT or MMT and possibly Start/Stop? Europe’s got it now. Let us hope to see the US receive it soon.
