2015 BMW M235i: Road Trips Help Fuel Economy

by Mike Schmidt, Vehicle Testing Manager on April 13, 2016

2015 BMW M235i

Our time with the 2015 BMW M235i convertible is coming to an end soon. But until March it was without many long distance road trips. That was about the time Cameron came up with an idea to drive the BMW to Zion National Park in Utah, an 870 mile round-trip. In the process he broke multiple existing fuel economy records.

2015 BMW M235i: Setting Records on its First Road Trip, Part 2

by Cameron Rogers, Associate Editor on March 23, 2016

We just arrived at Zion National Park in our 2015 BMW M235i. The park ranger at the front gate warned us that the roads would be a bit crowded through Zion Canyon Scenic Drive. An early-morning half-marathon was scheduled for the next day, and the park was lousy with runners and their families.

Even so, the road was long enough that vehicles were spread out, which made for plenty of traffic-less photos.

2015 BMW M235i: Zion Bound

by Cameron Rogers, Associate Editor on March 11, 2016

2015 BMW M235i

By the time you read this, I'll be driving the 2015 BMW M235i to Zion National Park in southwest Utah. I've had the idea of going on a road trip in the BMW since I wrote its January fuel economy update. At the end of January, the odometer was just about to turn over 14,000 miles, and it hit the 15,000 milestone at the beginning of March.

We try to get every year-long test vehicle to the 20,000-mile mark, which works out to about 1,700 miles per month. The M235i has hit this mark only twice since it's been with us. The current odometer reading is 15,764, and it's due to go back to BMW at the beginning of April.

It's time to make up for lost ground.

2015 BMW M235i: Fuel Economy Update For February - Slight Boost in Lifetime Efficiency

by Jason Kavanagh, Engineering Editor on March 10, 2016

2015 BMW M235i

Our long-term 2015 BMW M235i saw its electron-related features under the microscope during February. Its keyless ignition sans entry, leisurely power-folding top and chicken-little-ing parking alerts came under heavy scrutiny.

In between these ruminations, the BMW also saw a decent chunk of road time during February — 1,215 miles, to be exact. It managed 23.3 mpg for the month, bringing its rolling lifetime fuel economy to 20.9 mpg. This lines up with its EPA city rating of 21 mpg.

2015 BMW M235i: Fuel Economy Update for January — Commuting Takes its Toll

by Cameron Rogers, Associate Editor on March 1, 2016

2015 BMW M235i

Although it was in the hands of one of our editors nearly every night in January, the odometer of our 2015 BMW M235i moved little. In fact, its 1031.6 logged miles were just half-a-mile less than the distance we drove it in December.

We consumed a touch more fuel, so monthly fuel economy in January was 19.23 mpg compared to December's 19.46 mpg. Overall economy also fell slightly from 20.9 mpg to 20.7 mpg.

2015 BMW M235i: Fuel Economy Update for December - Achieving Combined MPG Requires the Improbable

by Jason Kavanagh, Engineering Editor on January 11, 2016

2015 BMW M235i

Our long-term 2015 BMW M235i continues to win us over with its lusty, turbocharged silken propulsion device. It begs the driver to open the taps and twist the tach needle to the five-o'clock region of its gauge.

2015 BMW M235i: Going Eco Pro

by Carlos Lago, Road Test Editor on November 25, 2015

2015 BMW M235i

Press up on the rocker switch next to the shifter in our 2015 BMW M235i and you go into Sport mode. All is good in the world.

But what happens when you press back? While spending two hours in stop-and-go traffic this week, I decided to find out and explored the decidedly less fun world of Eco Pro.

2015 BMW M235i: Fuel Economy Update for October: Quiet Month, Incremental Gains

by Cameron Rogers, Associate Editor on November 10, 2015

2015 BMW M235i

We added only 1,200 miles to the 2015 BMW M235i's odometer in October, but we still managed to bump the convertible's lifetime average fuel economy from 21.0 mpg to 21.2 mpg. The majority of the fill-ups hovered around the 21 mpg mark, which is also the M235i's estimated fuel economy in city driving.

A couple of trips that Dan Edmunds took to Auto Club Speedway (averaging 26.2 mpg) are responsible for the marginal uptick in fuel economy.

2015 BMW M235i: Busy Weekend Highlights Impressive Engine, Pushes Odometer Past 10,000 Miles

by Dan Edmunds, Director of Vehicle Testing on October 23, 2015

2015 BMW M235i

Last weekend was a busy one and I put some decent miles on our 2015 BMW M235i without actually leaving town on anything I would call a road trip. I shuttled my daughter around some and ran a few errands, but at least half of the miles came from two round-trips between my home and Auto Club Speedway in Fontana, where I helped officiate at a Cal Club SCCA race weekend.

I love the BMW's power. It gets the car up to speed with little apparent effort and the feeling of torque is expansive. It feels like it could go on forever. I need to sign this one out more often.

2015 BMW M235i: Fuel Economy Update for August - Best Tank Yet Still Falls Short of Highway Rating

by Jason Kavanagh, Engineering Editor on September 14 2015

2015 BMW M235i

One of the fuel fill-ups scrawled into our long-term 2015 BMW M235i's log book sometime in August was the car's highest-recorded fuel economy to date: 28.6 mpg. Still, this is short of the car's EPA highway rating of 32 mpg.

2015 BMW M235i: Fuel Economy Update for July — New Record

August 14, 2015

2014 Mini Cooper

Our 2015 BMW M235i proves to be a popular car, as it sat in the Edmunds garage only two nights in July. Most of those nights, however, it went home with editors who live in the immediate vicinity of the office. This accounted for 1,322 miles, slightly off pace from our 1,700-mile goal. Something tells me a sunny, top-down road trip is not far off in our convertible's future.

2015 BMW M235i: Fuel Economy Update for June - Just Getting Started

July 7, 2015

2015 BMW M235i

Our 2015 BMW M235i served light-duty commuting duties through most of June. No road trips, no track romps, no long-distance cruising (although we did pull a very good tank comprised of some long highway commutes). Instead we used it for the fairly blue-collar task of hauling new Mustang tires, driving the dog around (Mya was not impressed) and waxing on the really, really nice powertrain.

We still managed to add almost 1,600 miles though, and observed one tank that returned 25.5 mpg after 311 miles. That's our second best-fill so far and maybe a more legitimate result than the standing record of 25.7 mpg, achieved with just 123.6 trip miles back in April.
