Ford leaks out 2.7-litre EcoBoost data

Ford is peeling away piecemeal, in a somewhat erratic fashion, details of its ground-breaking 2.7-litre V6 EcoBoost engine that powers the 2015 F-150 pick-up truck.

Further details it seems will be released in September at the Texas State Fair in the US.

Earlier this week a select few journalists witnessed the weigh-in of the new aluminium-intensive truck at Ford’s Dearborn facility, in Michigan.

The new standard 2.7-litre V-6 EcoBoost will provide 283bhp (211kW) horsepower and 255lbft (345Nm) torque, enabling the base 2015 F-150 to tow 7,600lb and carry a payload of 1,910lb.

This is a best-in-class tow rating for V-6 light-duty pickups, according to Ford.

But another power option of the new turbocharged 2.7-liter EcoBoost V-6 has a rating of 325bhp (242kW) and 375lbft (508Nm) torque.

The engine is as powerful as most other truck makers' midrange V-8 engines, according to Ford, enabling an F-150 equipped with the 2.7-litre engine to pull 8,500lb and haul a payload of up to 2,250lb.

Sources in Ford suggest this could be the volume engine, comprising fully half of its expected engine mix.

According to Ford, 85 percent of F-150 buyers tow less than 8,500lb and carry a payload less than 2,000lb.

In terms of specific torque the standard 2.7-litre EcoBoost engine of 345Nm has a specific torque of 128Nm/l. On the basis of specific power rating, the same standard 2.7-litre EcoBoost engine of 211kW has a modest specific power of 78kW/l.

The more powerful 242kW version of the 2.7-litre EcoBoost, also with a compacted graphite iron (CGI) cylinder block, offers a specific power of 90kW/l, about the same as a VW 2-litre Golf TSI of 90kW/l with an output of 169kW and 350Nm torque  

Volkswagen’s top-of-the-range 2-litre engine in the Golf R400 of 294kW (394bhp) and 450Nm (332lb ft) torque gives a specific torque of 225Nm/l and almost 150kW/l specific power.

So the new Ford gasoline engine has plenty in hand in terms of further long-term scope for development, like 400bhp and 445lbft torque?
