TOKYO, Japan, April 5, 2012 - Honda Motor Co., Ltd. announced the development of a new continuously variable transmission (CVT) for midsize vehicles that significantly enhances both driving performance and fuel economy. The new CVT is the latest addition to the Earth Dreams Technology series of revolutionary next-generation technologies for automobiles. Also announced today, the all-new Step WGN and Step WGN Spada will be the first vehicles to feature this new CVT and will offer the highest fuel economy in their class*1.
To enhance fuel economy, the new CVT is compatible with an idle stop system and features a high-efficiency electric oil pump among other features. In addition, the G-Design Shift, a new coordinated control system for gearing, throttle and hydraulic control, responds quickly to driver input, maintains strong and smooth acceleration G and helps realize an exhilarating and sporty driving feel. Thanks to this combination of technologies, in a comparison of vehicles in the same class, the new CVT offers 5 percent higher fuel economy than a conventional CVT and 10 percent higher than a 5-speed automatic transmission*2.
In November 2011, Honda announced Earth Dreams Technology, a series of next-generation technologies for automobiles that significantly enhance both driving performance and fuel economy, combining environmental responsibility with the fun driving customers expect from Honda. The first technologies in the series were the newly developed engine and CVT for minicars that were featured on the N BOX. The new CVT for midsize vehicles featured on the all-new Step WGN and Step WGN Spada is the second technology to join the series.
