Ford Performance Vehicles has just announced details on its all-new V8 engine, named the “Miami” V8.

Set to replace the old faithful Boss V8, the new Miami is a supercharged 5.0-litre unit based on the Coyote V8 currently serving in the Ford Mustang. The Miami will be available in two power outputs within FPV’s model range.

The GS sedan and ute will receive the lower-output Miami V8 (coded V2X) producing 315kW and 545Nm. The full-strength high-spec engine (coded V2G) pumps out 335kW and 570Nm and will be fitted to GT- badged vehicles. Both engines are almost identical mechanically, with only ECU tuning accounting for the difference in output.

These numbers represent a significant jump over the current GS and GT engines, which put out 302kW and 315kW respectively. Further to that, the GT’s 335kW beats out the 325kW output of HSV’s flagship GTS by a full 10kW margin. This should guarantee FPV owners bragging rights for some time.

The shift to a supercharged mill has also allowed FPV to increase torque, even though engine displacement has dropped by 400cc. The full compliment of torque also comes on much lower in the rev range at just 2000rpm for the GS and 2200rpm for the GT.

There is no word yet on exact performance figures from FPV, but there are already suggestions that the new FPV GT could go 0-100km/h in under 5 seconds.

It’s good news in terms of economy as well, with a slight improvement in consumption seeing the GS and GT manual sedans drinking 13.6 l/100km. Automatic sedans use 0.1 l/100km more.

In terms of styling FPV isn’t making any major external changes for now, with the improved powertrain expected to gather serious interest for now.

The 2011 FPV GS and GT will be unveiled at Bathurst on October 7 and go on sale in Australia from next month. NZ pricing and availability should be announced shortly.
