Honda develops new CVT for midsize vehicles

Honda is a car manufacturer that has always been toying with the idea of CVT transmission. Back in 1995, the Japanese automaker introduced the Multimatic CVT gearbox in the EK Civics. Coming back to 2012, Honda has announced the development of a new CVT transmission for midsized vehicles that claims to improve fuel economy and driving performance.

The new CVT is Honda’s latest addition to the company’s ‘Earth Dreams Technology’, which is a set of powertrain initiatives designed to enhance both driving performance and fuel economy. The all-new Step WGN and Step WGN Spada in Japan will be the first vehicles to feature this new CVT and will offer the highest fuel economy in their class based on Honda computation.

The new CVT system can be paired up with an idle-stop system and features a high-efficiency electric oil pump and high-strength belt among other features. The infinite gear ratio offers enhanced torque in the lower rpm range and increases the take off power at traffic light. Honda’s latest transmission promises 5% higher fuel economy than a conventional CVT and 10% higher than a 5-speed automatic transmission, based on Honda vehicles in the same class.

It would be interesting to see how Honda’s latest transmission matches up against the increasingly popular dual-clutch transmission (DSG) in terms of fuel efficiency. In a recent interview with JATCO’s president (a key CVT producer), he commented that DSG has an advantage in fuel efficiency but CVT is more compact in size.

I have been a car fanatic since 1989, when my father was changing our family car then to a Toyota Corolla 1.6 GL fitted with a Twin Cam 16 valve engine that was carburetor-fed, a big deal back in those days. The automobile technology and industry fascinates me and I hope to broadcast these interesting developments to everyone out there through this blog.
