Незнам за РХ-7, но Мазда яко си хвалят Ренезис-а. Немал нищо общо с недъзите на предните поколения ротори.
Само ще цитирам -
"The naturally aspirated Renesis produces 238 hp (178 kW) - compare this to 255 hp (190 kW) for the twin turbocharged 13B in the Mazda RX-7.
The Renesis engine won International Engine of the Year and Best New Engine awards 2003. It also holds the "2.5 to 3 liter" size award for 2003 and 2004, where it is considered a 2.6 L engine. Finally, it was on the Ward's 10 Best Engines list for 2004 and 2005."
