Daimler And Ford Exchange 3-Cylinder Engine Tech

ecoboost_2Are three-cylinder engines the future of automobiles? These tiny motors have certainly gained a lot of popularity in the past few years, with companies like Ford leading the charge on turbocharging and downsizing. This has intrigued Mercedes, which has shared some of its own fuel-saving technology to get a closer look at Ford’s three-cylinder EcoBoost engine.

This is at least the second tech alliance between these two companies. Earlier this year Ford and Mercedes joined Nissan in an alliance aimed at producing and selling an affordable hydrogen fuel cell car by 2017. The technology exchange gives Daimler a look at Ford’s award-winning three-banger EcoBoost, which reps called “interesting” and “impressive.” You don’t say?

In return, Ford is checking out Mercede’s stratified lean-burning gas engines, which already meet the strict Euro 6 emissions demands. This technology exchange should benefit everyone, though Mercedes is arguably getting the better end of the deal, as the Ford three-cylinder engine is a big hit in Europe already. That is thanks to its great fuel economy, with over 60 mpg in the U.K. Focus, while still delivering a healthy 123 horsepower.

Apparently, three-cylinder engines are a big hit with the engineering crowd. Quite the shift from the gas-guzzling V8s that dominated roads just a decade ago. Makes one wonder though if Mercedes and Ford aren’t getting a little too comfortable…

    Three cylinders were a good idea since the Geo/Chevy Metro back in the 1990′s. As far as I know, the Metro XFI at 53 mpg city, 58 mpg highway still holds the title for best fuel economy in a non-hybrid car.

      I owned a 95 Metro I3 1L. It was rated at 49mpg highway, but never even came close. The Metro replaced Dodge Colt with a 1.5L I4. The Colt would run circles around the Metro and get the same mileage. I also owned a 94 Escort wagon at that time. The Escort nearly matched the Metro in mileage, but was twice as roomy and was twice as powerful, had many more features, and was even pleasant to drive . The Metro was the worst new car purchase of my life, so far. I never could get GM or any of it’s dealers to address the mileage deficit. They always cited YMMV. I pointed out that my other cars where doing better than rated, I am the same driver on the same roads, filling at the same pump, the variations shouldn’t be in the opposite direction. I learned how little GM cared about customers, and have never bought a GM anything since. It didn’t surprise me when they went bankrupt. The Metro was hit by an inattentive driver, and even though it was not totaled, I took the cash and sold it as is with only 50k mi. I was never so happy to get rid of a car. The Colt had nearly 150k mi when I gave it to a family member, the Escort went over 1/4 million miles before someone in a mini-van rear-ended it.

    SMART car has a smaller engine? even a diesel? and an electric option? Will we see a Ford/Mercedes SMART car from Ford’s factories in China soon? Kubota tractors have a three banger diesel or gas engine too? Everybody running hard to destroy the electric market niche before it is established?

    This is good news. We need more efficient vehicles. I just with that the big three would also look at turbo diesels like VW currently offers.
