Which is the fastest twin engine piston airplane?

There are only four twin-engine piston airplanes on the market today. Only two sell.

The two that sell are the Piper Seminole, which cruises at 160mph, and the Diamond DA42, which cruises at 198mph. They're not currently making the DA42 because the engine builder is in receivership. Both of these planes are primarily used as trainers.

Piper Seneca V's cruise at 196mph, and Beechcraft Barons cruise at 232mph. These don't sell because if you're in the market for a twin, used King Airs sell for about that much and those are equipped with the far-more-reliable Pratt & Whitney PT-6 turboprop.

Actually your missing the aerostar 702 and 700 its the fastest twin out there,
