New Euro 5-compliance laws come into effect from next year, causing Mazda to update the 1.6-litre MZ-CD common-rail diesel engine to improve fuel economy by 2.2 per cent and cut emissions by 1.7 per cent to 117g/km.
The Mazda3 family car’s new diesel engine will be matched to a six-speed manual transmission and will include an updated fuel injection system and a variable-geometry turbocharger.
The engine will deliver 115ps at 3,600rpm and 270Nm of torque – 30Nm more than the outgoing model.
It will also feature a maintenance-free diesel particulate filter (DFP), which stops pollutants particulates from the exhaust emissions.
A top speed of 116mph will be attainable with the new diesel engine along with a 0-62mph sprint time of 11 seconds.
The engine will be available on the five-door hatchback version of the Mazda3 and will join six other petrol and diesel engines in the line-up.
Released in 2009, the Mazda3 features Mazda’s new face and includes more equipment than previous generations.
Competing with the likes of the Ford Focus can be difficult, so Mazda has included features such as air conditioning, power door mirrors and MP3 capability as standard.
Higher trim levels add much more equipment, including climate control, Bluetooth, Bose premium surround sound system, rear parking sensors and an integrated sat-nav system with 4.1-inch display.
In the case of the new Mazda3, the Japanese manufacturer can also claim to have one of the safest cars in class after it received a five-star EuroNCAP safety rating.
Driving assistance such as dynamic stability control, traction control, ABS and brake assist all improve the safety and driving dynamics of the Mazda3.
