What makes the 2.2-liter, dual-stage turbocharging, 4-cylinder SKYACTIV-D engine special is its combination of light weight, high performance, high fuel efficiency and clean emissions. Altogether, these traits make the SKYACTIV-D diesel engine comparable to competitors' gasoline-engine, gasoline-electric hybrid or plug-in hybrid vehicles.
The 14:1 compressions ratio (compared to typical 16:1 to 18:1 diesel compression ratios), is the industry's lowest for improved fuel efficiency and reduced NOx soot emissions
·More efficient combustion timing
·Dramatically lighter components results in a 10% weight reduction for improved overall vehicle performance, handling and braking
·Two-stage turbocharger for great response and improved torque output
·Variable valve lift for exhaust valves stabilizes combustion for reduced misfiring after cold starts
·20% better fuel economy than other contemporary diesel engines
·Among the first diesel engines to meet tough Tier II BIN 5 North American emission regulations without an auxillary NOx trap catalytic converter or catalytic reduction after-treatments
·Active ceramic diesel particulate filter further reduces exhaust emissions
The factory Mazda squad has moved from the now-defunct GX class to the premier category with its new SKYACTIV-D-powered Lola-based prototypes, which make their public debuts in this weekend’s Roar Before the Rolex 24. Utilizing the same 2.2-liter four-cylinder turbodiesel engine that was used in the Mazda6 GX cars last year, the Florida-based operation has spent the recent months pairing its proven powerplant with the Lola B12/80 chassis...
... the proposed rules stipulate that a turn-key LMP3 car cannot sell for more than 150,000 Euros ($202,000).
