Nissan Motor Co., Ltd., unveiled the new Nissan Note, a global B-segment compact car, at a world premiere held at the Osanbashi venue in Yokohama. The new Note goes on sale in Japan this fall and in Europe in 2013. The new Note is a successor to the current model, which has sold 940,000 units since its launch in 2005.

Two new engines will be available to customers in Japan, including the new three-cylinder, 1.2L gasoline direct injection supercharged HR12DDR (DIG-S) (earlier post) and the HR12DE, which has received acclaim in the Nissan March.

The HR12DDR, which is based on the HR12DE, uses a high compression ratio (13:1) with a boosting system, a lower surface/volume ratio piston, and high tumble intake port to optimize direct injection combustion. A supercharger with a magnetic clutch compensates for the disadvantage of the small displacement engine with the Miller cycle without sacrificing fuel economy.

Combining the compact, lightweight next-generation XTRONIC CVT (Continuously Variable Transmission) for all grades with an Idling Stop System (start-stop) for 2WD, the DIG-S engine achieves fuel economy of 25.2 km/L (59.3 mpg US, 4.0L/100km) on the JC08 cycle.

The new Note also features a lightweight platform and improved aerodynamics.

The new hatchback includes Nissan’s advanced Around View Monitor (AVM) which is included for the first time in a compact car, helping to take the stress out of reversing and parallel parking in tight spaces.

The new Japanese-market Note will be manufactured at Nissan Motor Kyushu. Nissan’s Sunderland plant in the UK will produce models for Europe, which are planned for release in 2013.

I may be nitpicking but I guess the author meant"a lower surface/volume ratio combustion chamber" and not "a lower surface/volume ratio piston"...
