Mercedes-Benz C300 Fuel Economy

May 29, 2008

I've said it before and I'll say it again: "Our C300 feels so utterly over-engineered and under-stressed that it will easily drive half a million miles before anything will need replacing." At least that's what it feels like. Few cars have this quality and it's really hard to put into words.

Part of it may have to do with the fact that the sturdy body in white is built to endure everything from decades of diesel-powered taxi service in the old country to thundering around racetracks in the form of a nuclear-powered 450-hp C63 AMG. That's a wide range of duty for a platform to accommodate, and not many manufacturers build their cars to this standard.

I had the C300 over the Memorial Day weekend and made a 430-mile lap from L.A. to the central coast and back. Though mildly congested and highly patrolled, I managed to make excellent time in both directions on Highway 101 and still earn decent fuel economy.

After I pulled into my driveway on Monday, the car's on-board computer reported "Since Start: 214 mi, 03hr:26min, 26.8 mpg, 63 mph." That's a bit of a surprise because the car is only rated at 18-mpg in the city and 25-mpg on the highway. So even at my sometimes-rapid pace, I managed to beat the EPA's highway number by almost 2 mpg.
