Ah the skyactiv-d... such science...
In any case, their comments for improved pace (whatever that may be) over the old diesel should provide some good comedy next year. Trying not to undersell amazing skyacyiv-d, they will probably explain the petrol pace gain by the updates they did to the Lo... MAZDA PROTOTYPE over the winter. The chassis which will look exactly the same as it did years and years ago...
Well at least the Lolas look good, which can't be said for too many prototypes in States now.
