This month, Ward’s explores the history of GM’s direct-injection 2.4L Ecotec I-4. A quick count of this year’s 10 Best Engines award winners reveals no fewer than six 4-bangers: two turbocharged, two HEVs, one diesel and even one naturally aspirated, workaday 4-cyl. engine – General Motors Co.’s 2.4L Ecotec. “In the Equinox,” Ward’s editors raved, “this engine never fails to delight with ready throttle response and strong mid-range acceleration.” Several were “astonished to achieve 30 mpg (7.8L/100 km) in the Equinox in mixed driving, without babying it.” And we’ll bet some, if they had not known it was a 4-cyl., might have mistaken it for a V-6 as many other reviewers have.

It's built on a platform that's been around since the 1967 Toyota 2000 GT using Yamaha heads, and has been used around the world in various cars and forms since? BTW, it's one of the most reliable engine series around.

Depends on your definition of "excellent." I've had a 2.0 Cav and a 2.2 Corsica that both ran past +120k miles when I junked them because of body rot. Total engine work done: 1 water pump on the 2.0. +30 mpg highway, and +20mpg city. All "excellent" to me. Of course they were dogs accelerating. I rented a 2005 Malibu with the Ecotec for a long trip, and it was a world of difference. I was impressed. I'll might end up with an Ecotec in my next new used car. First I heard of them was a workmate with a Ecotec Malibu asked for my "dealing with mechanics" advice back in about 2002. His water pump failed and his mech told him he might need new heads. Only had about 60k miles on it. Turned out he didn't, but he still dished out $600 for the stuff under the cam cover. I read up the Ecotec a bit and saw it was OHC, and figured I'd never see one, being happy with pushrods, timing chains and external mounted water pumps. Still am, but I might not much choice when I get my next car. Wish we had the dealer mechs here like before. Shiden was one. They could tell you the good/bad about various engines because they saw them all day. In any case the Ecotec was a real game changer for GM. Too bad it's the ninth inning. I did see on an Ecotec forum a way to change out the water pump through a cam cover access panel without moving the timing belt. That was encouraging. Maybe I can get over my distaste for OHC. --Vic |
