What's Up With Ford's V6 Engines?
For all of eternity, or at least modern eternity (since the birth of 8-Bit Nintendo), Ford has sold various iterations of the Duratec V6 engine. For the past umpteen years, the company used a 3.0-liter engine making about 200 horsepower. Using premium go-juice and variable valve timing, the six-pot produced in the realm of 227 horses in the Jag X-Type or 220 in the Mazda6 (the latter on 87 octane). This engine was supposed to be retired with the introduction of Ford's excellent new Duratec 35 engine. That mill currently motivates the new Ford Edge. In bored-out form– to 3.7 liters– it provides power for the Mazda CX-9 and upcoming Lincoln MKS. So far, so good. Old engine (Duratec 30) out, new engine (Duratec 35/37) in. But Ford has announced a major overhaul of the older 3.0-liter engine for duty in the coming years. The new 3.0-liter mill will now make some 240 horsepower in the 2009 Ford Escape (previously, it was rated at 200 ponies). Now the 35 is a truly modern engine, can accept direct injection and turbocharging. But even in naturally aspirated form, it makes 250+ horses. So it really begs the question: why is the 3.0-liter engine still on the table? And if I can beg a little more even, why isn't the 3.5/3.7 liter V6 available in the Mustang instead of the crotchety old 4.0 liter V6? Oh, you forgot that one, didn't you? One more: wasn't CEO Alan Mulally all about eliminating production complexity? I'm sure there are good reasons why this hasn't happened here (and I love to hear 'em), but the Duratec 35 is all you need from this point onward. Let economies of scale bring the costs of the 35 down, and dump the old 3.0 and 4.0-liter engines. KISS, baby.
