2014 Mercedes-Benz CLA250 Getting Gas, the Long Way

July 21, 2014

2014 Mercedes-Benz CLA250

I neglected to refuel the 2014 Mercedes-Benz CLA250 before embarking on the final leg of our road trip, mostly because I wanted to see how long I could go before the fuel warning light turned on.

2014 Mercedes-Benz CLA250: Fuel Economy Update for April

May 7, 2014

2014 Mercedes-Benz CLA250

We added 2,719 miles to our 2014 Mercedes-Benz CLA250 odometer in the month of April.

Most of those miles were put on by James Riswick, whose road trip to the Redwoods significantly improved our lifetime fuel economy number, raising it from 24.9 to 27.2. And this is despite the technical difficulties he experienced during his trip.

2014 Mercedes-Benz CLA250: Redwoods Road Trip Wrap-Up

April 28, 2014

2014 Mercedes-Benz CLA250

After 10 hours driving from Eureka home to Los Angeles, my 2014 Mercedes-Benz CLA250 road trip to the Redwoods has come to an end. Along the way, I added 1,561 miles to the CLA's odometer and found that it's a far more enjoyable and comfortable car outside the congested confines of greater Los Angeles.

Here are some final notes from the trip.

2014 Mercedes-Benz CLA250: Redwood Road Trip Part 1

April 21, 2014

2014 Mercedes-Benz CLA250

I've been growing weary of the city. I'm tired of the traffic, the noise and the rude people. At the same time, our 2014 Mercedes-Benz CLA250 hasn't exactly been at its best in Los Angeles — ceaseless complaints about its clunky transmission in traffic, its rough ride on the city's horrific roads and sub-EPA fuel economy.

It was time for both of us to get the heck out of Dodge, or rather, escape to the towering trees, fresh air and majestic views of California's North Coast.

2014 Mercedes-Benz CLA250: Arizona Road Trip

April 17, 2014

2014 Mercedes-Benz CLA250

I needed wheels to get to Arizona for a Hyundai press event drive, so Edmunds' Car Czar, Mike Schmidt, assigned me our long-term 2014 Mercedes-Benz CLA250.

No problem, I had barely driven the new Mercedes and wanted to spend some quality behind-the-wheel time in it anyway.

Here are some thoughts from the 800-mile, almost-all-highway road trip:

2014 Mercedes-Benz CLA250: Fuel Economy Update for March

April 3, 2014

2014 Mercedes-Benz CLA250

During the month of March we covered 1,172 miles in our long-term 2014 Mercedes-Benz CLA250. We averaged 25.7 mpg for the month, which upped the Merc's lifetime average fuel economy to 24.9, from the previous 24.7.

But we continue to struggle to meet the EPA's ratings for the car of 30 mpg combined (26 city/38 highway).

2014 Mercedes-Benz CLA250: It Is Possible To Beat EPA Estimates, But Only for a Little While

March 13, 2014

2014 Mercedes-Benz CLA250

Granted, we've yet to validate the onboard fuel economy calculator in our 2014 Mercedes-Benz CLA250, but for now, we're going to say it works. Why? Because we've been struggling even to meet the EPA's city estimate of 26 mpg, so seeing the display report 39.8 mpg was a cause for celebration. The EPA says we should be able to earn 38 mpg on the highway.

2014 Mercedes-Benz CLA250: We Found a Semi-Useful Display

If you're a regular reader of this blog, you'll know that the fuel economy of our 2014 Mercedes-Benz CLA250 is a hot topic. We're continually striving to improve it. Well, some of us are. I've been driving it for a few days in the default Eco mode, both the transmission setting as well as the auto stop-start functions.

2014 Mercedes-Benz CLA250: Fuel Economy Update for February

March 5, 2014

2014 Mercedes-Benz CLA250

Despite somebody's best efforts to do the opposite (with a 16-mpg fill-up), the average fuel economy of our 2014 Mercedes-Benz CLA250 inched ever closer to the official EPA city estimate in February.

We added a commendable 1,200 miles since the last update, yet our car is still struggling to make the hoped-for numbers.

2014 Mercedes-Benz CLA250: Fuel Economy Update for January

February 4, 2014

2014 Mercedes-Benz CLA250

In November's fuel-economy update for the 2014 Mercedes CLA250, Director of Vehicle Testing Dan Edmunds wrote that he was concerned about the CLA's ability to hit its EPA ratings during real-world testing.

Two thousand miles later, it seems Dan's theory may be holding true. Although our CLA250 achieved 36.7 mpg for one fill-up, it's still holding below 25 mpg for its life-time average.

2014 Mercedes-Benz CLA250: Transmission Error

I might be in the minority here, but I am not a fan of the seven-speed dual-clutch transmission in our 2014 Mercedes CLA250.

2014 Mercedes-Benz CLA250: Fuel Economy Update for November

December 05, 2013

2014 Mercedes-Benz CLA250

It's way too early to draw any conclusions just yet. Our 2014 Mercedes-Benz CLA250 has just barely passed the 750-mile mark on the way to being broken in.

That said, we're driving our CLA gently in these introductory miles. I would have expected its MPG to be reasonable, at least. But so far this car's impressive-on-paper EPA ratings seem like wishful thinking in the extreme.

2014 Mercedes-Benz CLA250: Check Engine Light Reset Attempt

December 04, 2013

2014 Mercedes-Benz CLA250

A couple of days ago the Check Engine light winked on while another staffer was piloting our near-new 2014 Mercedes-Benz CLA 250. However, as is often the case, he couldn't correlate its arrival to anything special he was doing at the time. It did not come on during the startup sequence or while climbing a steep grade. He was just, you know, driving.

For its part, the car is fine. No hiccups, no reluctant acceleration, just the dang light on the dash. Well, maybe the fuel economy is a little underwhelming, but it's hard to be sure that's a thing with just 476 total miles on the clock.

I have a couple of low-cost OBD code scanners at home, so I hooked each of them up to see what they could tell me.

The first was the Scan Gauge II. It came back with a single diagnostic trouble code with an ominous-sounding title: P0004 - Fuel Volume Regulator Control Circuit High.
