For the future, Mazda is working on a hybrid and cooperation on hydrogen-drive, in the here and now comes a new start-stop automatic.

Alone within the past year, the Japanese – not least because of the success of the Mazda 2 – their average current consumption by eight per cent down. But for them the future is still not enough: “This is a significant step toward the goal, the total consumption of Mazda’s fleet by the year 2015 by 30 per cent,” says Bruno Mueller, Vice President Human Resources at Mazda Europe. The engineers want to achieve from the Far East, especially with a new generation of engines with gasoline direct injection and a start-stop automatic, in the next few years, coverage will be rolled out.
DISI from 32′650 francs

In Switzerland, this efficient combination of savings available now, but initially only in the Mazda 3 2.0 DISI i-Stop. The 32′650 francs available from two-liter engine is equipped with a manual 6-speed manual gearbox and makes 151 HP to 191 Newton meters. The transversely installed four-cylinder accelerates the car in just 10.4 seconds to 100 and reaches a top speed beyond the 20oer mark. Here he uses an average of 6.8 liters per 100 kilometers and is 14 percent less fuel than the engine with its predecessor. While the direct injection meanwhile can find almost everywhere, the Japanese at the start-stop automatic very own way. Although it is also necessary for them to take the course and the foot of the clutch, so the engine against the barrier or at the lights in the break to send.

Avoid losses

But the first time they use not only the force of the starter, but the combustion energy to him then when the clutch re-occur again. Therefore, the cylinder when the engine leveled so that always one of them in the work cycle is stopped, and at one point, the rapid restart of the engine favors. Then injected to start gasoline and ignite, the engine would be even without electrical assistance in motion. Weil also still the crankshaft is rotated, the engine starts softer and faster than all previously known systems: instead of 0.7 logs after the petrol after 0.35 seconds back. In the field test in summer temperatures, it turned out that the engine at traffic lights throughout the rare Rotphase stops. Because running too many electric consumers, it raises the system back to the engine when the battery charge falls below 85 percent. Thus, loss of comfort to the detriment of the occupants are avoided.

5 and Mazda RX8 with hydrogen

Not quite so far are the other ways in which Mazda consumption will reduce its fleet. On the one hand, according to media reports, a hybrid collaboration with Toyota to be negotiated, on the other hand, keeps you at Mazda in the vision of the hydrogen propulsion noted. Only a few days ago, Mazda presented in Oslo a small fleet of hydrogen-powered RX8, within the framework of a research project in Japan and Norway run. One step further is the Mazda 5 Hydrogen RE Hybrid: This system combines the hydrogen of the Wankel RX8 with a serial hybrid drive. “This car is for us a showcase of future technologies”, says research chief Seita Kanai.
