Mazda has confirmed UK pricing and specifications for Skyactiv-X-powered variants of the new 3.
The 2.0-litre four-cylinder powertrain, which uses the brand's newly developed spark plug-controlled compression ignition technology, can be equipped from £23,555. This starting price applies to both the hatchback variant and the saloon, which will arrive in the UK in October.
The unit will be offered with a manual or automatic gearbox, and is available on four trim lines: entry-level Sport, Sport Lux, GT Sport and range-topping GT Sport Tech, which tops the line-up at a starting price of £29,775 for the hatch and £27,575 for the saloon.
Sport trim comes equipped as standard with rear privacy glass, chrome detailing and a frameless rear view mirror, while Sport Lux adds keyless entry, a reversing camera and heated front seats. Higher up the range, GT Sport is offered with electrically adjustable leather seats, a heated steering wheel and Bose sound system, and top-spec models receive a 360deg camera and additional driver safety aids.
All Skyactiv-X models feature a 7in digital instrument display and Mazda's new 8.8in infotainment central display, but 18 in alloy wheels, black badges and a wider exhaust tailpipe are added beyond Sport trim.
The firm says the new engine combines the performance of a petrol engine with the fuel economy of a diesel.
The unit has been confirmed to deliver 178bhp and 165lb ft of torque, while producing a fuel economy of up to 52.3mpg on the WLTP cycle, with CO2 emissions from 96g/km. The economy and CO2 figures depend on model, wheel size and choice of gearbox.
The powertrain will also include Mazda's M Hybrid system, a 24V mild-hybrid unit that can regain energy under braking.
