Mooney says its Acclaim is now the fastest piston single.
Mooney is now formally laying claim to the title of fastest piston single with the final certification of its Acclaim. The aircraft, which was introduced at Sun ‘n’ Fun last April, sports twin, intercooled turbochargers on its 280-hp TSIO-550-G Continental engine. The airplane is said to hit 237 ktas while cruising at its 25,000-foot service ceiling. Next fastest is the Columbia 400, which is marginally slower (two knots so) with a similar engine (it’s a C model rather than a G). The Columbia model previously held the fastest title for several years.
