The door may barely have closed on the Frankfurt Motor Show, but it would appear that manufacturers have already set their sights on the next major date in the motoring calendar – the Tokyo Motor Show, which runs from October 24-November 4.
At the event, Mazda, which has just announced that it has achieved its best ever sales month in the UK in September, will showcase the world premier of its next generation engine line-up and automatic transmissions. It will also take the opportunity to give a debut to the Kiyora concept car.
Let's take a look at each of the debutants:
- The direct injection Mazda Sky-G petrol engine: With a newly designed engine block that is meant to reduce mechanical friction and achieve an optimal air-fuel mix, the Mazda Sky-G significantly improves fuel economy and output performance with enhanced thermal efficiency. Specifically, fuel economy and torque are boosted by approximately 15 per cent compared to Mazda's current 2.0 litre engine.
- Advanced diesel Mazda Sky-D engine: By optimising the pressure and temperature in the cylinders, as well as the fuel injection rate, the Sky-D engine begins combustion at the best timing in terms of thermal efficiency. It employs piezo injectors, a two-stage turbocharger and other technologies to offer fuel economy improvements of approximately 20 per cent compared to the current 2.2litre diesel engine.
- Mazda Sky-Drive automatic transmission: Highly efficient and contributing to substantially improved fuel economy, the next generation Mazda Sky-Drive has enjoyed a complete redesign that significantly cuts mechanical friction. Fuel economy is improved by around five per cent.
- Mazda Kiyora Concept: The Kiyora uses the Sky-G 1.3 engine and the six-speed Mazda Sky-Drive automatic transmission. It is aided by the i-stop idling stop system, regenerative braking and advanced aerodynamics to help it achieve fuel economy of 32km/litre under Japan's 10-15 mode test cycle – that's the equivalent of 75mpg US.
