24 MPG combined might not be impressive when compared to hybrid crossovers, but for the 2016 BMW M235i Convertible, it’s not the main concern. This car isn’t bought for saving money on gas; it’s bought for its fun handling, the power of its turbocharged inline-six, and the ability to drive with the top down. Fuel economy is less important than the thrilling driving experience.

City and highway performance

The EPA estimates the M235i Convertible gets 20 MPG in the city and 30 MPG on the highway. The city number shows how inefficient stop-and-go traffic is, made worse by the car’s quick acceleration. The 30 MPG highway rating is more realistic when driving, especially on long trips at a consistent speed. But, the desire to use the engine’s power will probably lower that number. The eight-speed automatic transmission (S8) helps get better mileage on the highway, shifting smoothly and keeping the engine at its most efficient. How you drive will greatly affect your highway fuel economy.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2016 BMW M235i Convertible is $2,400. This is based on driving 15,000 miles per year and using the national average fuel price. Premium fuel is recommended, which will increase the cost. If you drive more carefully or less, you’ll spend less. A more aggressive driving style or higher gas prices will make your annual fuel bill higher. Consider $2,400 a starting point that depends on how you drive and gas prices in your area.

Real-world expectations

The EPA estimates provide a standard for comparison, but actual gas mileage often varies. Some M235i Convertible owners say they average closer to 22 MPG in combined driving, with highway numbers dropping into the mid-20s in normal situations. These differences come from how you drive, traffic, and the terrain. If you often use the engine’s full potential or drive in heavy traffic, expect lower fuel consumption than the EPA estimates. If you drive more calmly, the EPA numbers are possible.

How it compares

The M235i Convertible is in the middle of its class for gas mileage. The Audi S3, with its 2.0-liter turbocharged four-cylinder, gets around 26 MPG combined, offering slightly better fuel efficiency. The Mercedes-Benz CLA250, also a four-cylinder turbo, has similar fuel economy. If you’re focused on saving fuel, these are good choices. But, they usually don’t have the BMW’s fun inline-six engine and the driving feel that comes with it. Many find the M235i’s compromise acceptable because it offers better driving and overall fun.

Tips to maximize efficiency

Avoid constantly using the M235i’s power, especially in city driving. Accelerating gently and anticipating traffic can improve gas mileage a lot. The turbocharged engine responds well to light pressure on the gas pedal, letting you keep your speed without burning too much fuel.

Use the M235i’s Eco Pro mode. This setting changes how the gas pedal responds and when the transmission shifts to save fuel, making it good for highway driving or slow city driving. It does reduce performance, but it can improve MPG without ruining the driving experience.

Make sure your tires have the correct amount of air. Tires with low air pressure increase resistance and reduce fuel efficiency. Check your tire pressure often and keep them inflated to the recommended levels listed on the driver’s side door. Correct pressure improves fuel economy, handling, and tire life.

Keep extra weight out of the car. More weight makes the engine work harder, using more fuel. Remove unnecessary items from the trunk or passenger area to reduce weight and improve fuel efficiency. This small change can make a difference over time and increase M235I MPG across all years.

Maintain the car according to the manufacturer’s instructions. Regular maintenance, like oil changes and air filter replacements, keeps the engine running efficiently. A well-maintained engine uses less fuel and performs better.
