Mazda has officially announced the full specifications of a brand new 1.5-liter diesel engine, designed to comply with new Japanese market emissions regulations. It's been specifically developed to go into the next Mazda2 supermini, known as the Demio in Japan, which is expected to come out this year.
The 1.5-liter is not a 3-cylinder, like Ford's or MINI's new small diesel engines. It's an inline-four unit displacing exactly 1,497cc, with a bore of 76mm and a stroke of 82.5mm.

Much like the 2.2-liter diesel Mazda offers on the 6 and CX-5, it runs low compression compression ratios (14.8), which might make the engine feel almost like a petrol one. The list of technologies fitted to the new 1.5 Skyactiv-D include a reduced friction cylinder head, high-dispersal solenoid direct injectors, variable geometry turbo and an intake pipe integrated into the intercooler for improved thermal efficiency. Mazda says that its 1.5-liter already complies with Euro 6 emissions standards without the use of NOx after-treatment.

So what about performance? The small diesel engine produces a respectable 105 PS (77 kW) at 4,000 rpm and 250 Nm of torque from 1,500 to 2,500rpm. That's on par with Renault's 1.5 dCi and VW's 1.6 TDI. It's quite a lot for a subcompact class like the Mazda2 vehicle and could mean the next generation is a small diesel performance benchmark of sorts.
