  A full sot of acceleration figures is not available. Zero to sixty and to a hundred in 9.3 and 22 sec respectively, figured as near as may be tjy converting from somewhat jittersome r.p.m. readings, is the best that can be offered in that line of data; both were timed with screen up and a passenger, incidentally.
