Checking the competition, Audi and Mercedes have always been a major rival of the BMW cars. The M240i gets a direct competition from Audi's S5 Cabriolet and Mercedes Benz's AMG C43 Cabriolet. If we look at the rivals, their performance parameters are much comparable to the M240i but at the same time there selling prices are a bit too high.

The rear wheel drive for sure! It can burn rubber like a premium performance car, and yet still be easy on the pocket.

2017 BMW M240i Convertible Engine

9.6/10
As the BMW M235 becomes the M240i, the most significant change takes place under the hood...

...Other tweaks include auto rev matching for manual-equipped 2 Series models and wider gear ratios (automatic models) to improve fuel economy. -Digital Trends

Engine and transmission

Seeking beneath the bonnet of the M240i Convertible, there is a mighty 3.0-Litre TwinPower Turbo V6 engine that powers the vehicle. The maximum power offered by the engine is 335 hp while the maximum torque is 369 lbs.-ft. The convertible employs an 8-speed automatic transmission with the option of selecting the manual shift mode.

Models BMW M240i Audi S5 Cabriolet Mercedes Benz AMG C43 Cabriolet
MSRP $49,050 $61,100 $60,400
Engine 3.0L TwinPower Turbo Inline 6-Cylinder 3.0L TFSI V6 DOHC 3.0L V6 Biturbo

Torque 369 lb-ft @ 1520 rpm 325 lb-ft @ 2900 rpm 384 lb-ft @ 2000 rpm

Evaluating the competitors of the little BMW Convertible, the highest power and torque is offered by the Mercedes C43 AMG. Conversely, the S5 is the least powerful, though not by much. For transmission, the Audi Cabriolet utilizes a 7-speed automatic transmission whereas, the Benz comes fitted with a 9-speed automatic transmission.

Acceleration

With the 0-60 mph acceleration time of 4.7 seconds, the Beemer is blazingly fast. One of the biggest advantages of BMW M240i over its rivals is its low emission figure, which corresponds to 7.0 tons/year.

The 'AMG' is faster than the 'M', reaching 60 mph from a standstill in just 4.6 seconds. Moreover, the quarter mile time of AMG C43 is also the least at 13.1 seconds, followed by M240i's 13.2 seconds.

Ride and Handling

The ride quality of the M240i Convertible is outstanding thanks to its features like adaptive M suspension, twin-tube gas-pressure shock absorbers, dynamic stability control, and dynamic traction control. No matter at what speed the BMW M240i Convertible is moving, it always feels confident behind the wheel due to its variable sports steering.

Additionally, the convertible comes with M sports brakes along with dynamic brake control and cornering brake control to ensure complete speed regulation. The M240i offers four different driving modes namely Eco Pro, Comfort, Sport and Sport+ mode that varies the throttle response and gear ratios of the car.

Braking

For decelerating the vehicle on time, the tiny beemer comes equipped with 13.4-inch brakes at the front and 13-6-inch brakes at the rear.

2017 BMW M240i Convertible Fuel Economy

6.1/10

BMW's superlative fuel economy is what makes it stand out from the rest of the competition. The M240i offers 21 MPG of fuel economy in city conditions while this figure increases to 32 MPG when the car runs on highways.

MPG (city) 21 18 19
MPG (highway) 32 26 26
MPG (combined) 25 21 22

2017 BMW M240i Convertible Interior

9.0/10
Slip inside the 2017 BMW 2 Series and you'll find highly adjustable sport seats that provide good support in spirited driving and above-average comfort on extended jaunts. The rear seats are as cramped as you'd expect from a car this size, making them best suited to small children or as a place to stash a jacket, purse or backpack. -Edmunds

Seating and Comfort

Inside the BMW convertible, it can barely accommodate 4 passengers at a time, two adults in the front and two kids counting the driver. Observing the space available for the passengers within the front row, the little M offers 40.5 inches of headroom, 54.4 inches of shoulder room and 41.5 inches of legroom.

Model BMW M240i Audi S5 Cabriolet Mercedes Benz AMG C43 Cabriolet
Passenger capacity 4 4 4
Front (Head/Shoulder/Leg) (In.) 40.5/54.4/41.5 40.0/54.3/41.3 38.8/54.8/42.0
Second (Head/Shoulder/Leg) (In.) 37.0/42.2/31.8 36.3/46.8/31.9 35.6/51.7/32.0

After comparing with the rivals, it can be concluded that the M240i has the largest headroom while the shoulder room and legroom are maximum in the Mercedes Benz AMG C43 Cabriolet. On the other hand, the largest shoulder room of 51.7 inches and legroom of 32.0 inches is again available with the Mercedes AMG C43.

The M240i comes with a 6.5-inch infotainment system powered by the iDrive 6.0. The infotainment system supports

  • Navigation
  • Voice-commands
  • Satellite radio
  • Speed sensitive volume control
  • 7-speaker system with 205 Watts stereo output
  • Apple CarPlay (Optional)

Interior Features

The interiors of the Beemer are mesmerizing and there are many convenience features loaded inside which are no less than what's expected from a BMW. Following are the key attractions on the inside of M240i convertible:

  • Aluminum Hexagon interior trim
  • SensaTec upholstery
  • Three-spoke steering wheel with M-branding

Cargo Volume (ft.3) 11.8 10.2 8.8

Both the Audi S5 and Mercedes Benz AMG C43 have relatively smaller cargo capacities of 10.2 and 8.8 cubic feet respectively.

2017 BMW M240i Convertible Exterior

9.4/10
Befitting the "M" designation, the M240i dials up the visual muscularity to back up its additional performance. It boasts a deeper front spoiler, larger air intakes, contoured rocker panels, and a unique rear lower valance. Like most drop-tops, the convertibles look better top-down.  - Kelly Blue Book

Dimension and Weight

BMW M240i convertible is the lightest vehicle among the competitors with a curb weight of 3790 lbs. The convertible has a length of 175.9 inches and width of 69.8 inches with both the dimensions shorter than the other two rivaling cars.

However, the passenger space at the second row of S5 is superior to that of the M240i convertible.
