Ford Fiesta Black EcoBoost 140Ford will showcase its new 2014 Fiesta 1.0 EcoBoost 140 at the Goodwood Festival of Speed 2014 this weekend with an amazing stat – it has more power per litre than Jim Clark’s Lotus 49 F1 car!

The DFV-engined Lotus racer was the first car to use Ford’s legendary V8 engine, and was seen for decades as being ahead of its time. But Ford has finally beaten it – and has claimed a few more eye-opening supercar scalps in its power per litre achievement, too.

The Bugatti Veyron, for example, has just 125hp per litre; the Fiesta also beats the Ferrari 458 Scuderia and both the Ford GT40 and Ford GT. Indeed, most high performance engines you can mention don’t have the power density of the Ford 1.0 EcoBoost 140. Not bad for £15,995…

Ford head of gasoline powertrain development Andrew Fraser said it wasn’t a huge job to push the EcoBoost engine – launched in 100hp and 125hp guise – up to 140hp. Indeed, even more than that was achieved during testing.

“We saw 150hp on the dyno during development. However, some of the peak pressures in the cylinder head were a bit high at times; in the interests of longevity, we decided to cap it to 140hp.” Ford has a strict 150,000-mile engine durability sign-off test, and the 140hp cap was made with this in mind.

“That’s not to say we couldn’t achieve more in the future – this is an extraordinarily flexible engine.” How flexible? Well, the Formula Ford EcoBoost single-seat racer produces more than 200hp simply by the replacement of the regular turbo with one from the Fiesta ST – that genuinely is, emphasised Fraser, the only significant change to the engine.

Lotus 49 to be auctioned at Goodwood FoS

Despite its ‘lack of power’ seeing it be beaten by a Ford Fiesta, the Lotus 49 remains legendary. Rich racing fans will get a rare opportunity to buy a famous example of one at FoS this weekend too, in the annual Bonhams Goodwood auction.

An ex-Graham Hill Lotus 49, also driven by British Le Mans winner Richard Attwood, will be auctioned in the Saturday sale – with estimates of up to £1 million for the 1968 racer.

James Knight, Bonhams group motoring director, said: “This car, chassis ‘R8’, was Graham Hill’s – it was also raced by that wonderful driver Richard Attwood to set fastest lap at Monaco in 1969, and private owner Dave Charlton drove it to become South African national Champion.

“Add the excellent provenance of it being offered direct from the famous Dawson-Damer Collection and plainly ‘R8’ is an iconic car.”
