| Powertrains - Even more Driving Enjoyment
- All engines deliver improved fuel consumption
- MZR 2.0-litre now with S-VT and electronic throttle
- New six-speed manual transmission and updated four-speed automatic
Mazda3's emotional appeal goes deeper than good looks and easy to use practicality and comfort. Another of its most attractive features is its sporty, fun to drive nature. Beneath the skin of both body styles are the same engines as the outgoing model, but retuned, updated and enhanced to deliver even better acceleration feel and low-end torque, while using less fuel. In other words, with Mazda3 facelift it's even more driving enjoyment.
MZR 2.0-litre petrol - quicker, faster, more fun to drive
The top of the range MZR 2.0-litre petrol engine has been updated for the Mazda3 facelift to have better torque charac- teristics, improved acceleration feel, to use less fuel and now has a new six-speed manual transmission. Sequential valve timing (S-VT) is added to optimize intake valve operation 24 according to actual running conditions, which achieves a high charging efficiency. Combined with this engine's variable induction system, S-VT helps this Mazda3 deliver powerful torque throughout the rev range for enhanced driveability. So while this engine produces the same maximum power of 110 kW/150 PS at 6500 rpm, it reaches its maximum torque of 187 Nm at 4000 rpm, which is 500 rpm earlier than the outgoing model (4500 rpm). How the MZR 2.0-litre petrol accelerates, the so-called acceleration feel, has also been improved with a newly adopted electronic throttle, which makes this engine seem even more lively and spirited.
Transmissions - new six-speed manual transmission for MZR 2.0-litre petrol and updated automatic
And to enhance the driving fun even more, the MZR 2.0-litre petrol is now available with a newly-introduced six-speed manual transmission. This transmission features triple-cone synchronizers for first and second gear, and double-cone synchronizers for third and fourth gears. Wider use of double and triple-cone synchronizers gives a sporty, short-stroke feel with less shift effort. Sixth gear has a high-ratio to contribute to improved quietness at high speed as well as enhanced fuel economy. All other engines retain the five-speed manual transmission as standard. This gearbox has contributed to Mazda3's fun to drive character since launch, and is now further refined with improved clutch operating feel. The MZR 1.6-litre petrol engine can still be ordered with an electronically controlled, four-speed automatic transmission (depending on market), which allows the driver to drive in automatic mode or with sequential manual shifting. It has been updated to deliver a smooth, linear and direct feel to complement engine performance.
MZR 1.6 and 1.4-litre petrols - improved acceleration feel
The most popular engine in the line up - the MZR 1.6-litre petrol engine with a maximum power output of 77 kW/105 PS at 6,000 rpm and maximum torque of 145 Nm at 4,000 rpm - retains the same S-VT and VIS as the original model. The base MZR 1.4-litre petrol engine did not escape an update either. Designed for more cost-conscious drivers, it still produces 62 kW/84 PS of maximum power at 6,000 rpm and 122 Nm of maximum torque at 4,000 rpm, but now has newly modified valve timing based on the S-VT already employed. This heightens charging efficiency at low engine speeds and 26 enhances torque at low and middle engine speeds for powerful, easy driving.
Mazda3's MZ-CD turbo diesels
The MZ-CD 1.6-litre common-rail turbo diesel engine remains in the Mazda3 facelift line up for Europe. Two power derivatives are available (according to market), a Standard Power version with maximum power output of 66 kW/90 PS and a High Power version with 80 kW/109 PS at 4,000 rpm and maximum torque of 215 Nm and 240 Nm at just 1,750 rpm respectively. Both deliver an exceptional balance of power, low fuel consumption and emissions and low NVH. Both of these DOHC 16-valve engines feature all-aluminium construction for low weight and high rigidity, along with a 1600 bar ultra-high pressure common-rail injection system. The standard powered diesel employs a fixed geometry turbocharger and the higher powered diesel employs a variable geometry turbocharger and also a diesel particulate filter.
