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.
