The new car will initially be available with a choice of four engines, including a new 2.0-litre diesel for the 220d and, for the first time in a BMW convertible, an M Performance variant, the M235i. Fuel economy improvements over the previous model average 18 per cent. The 2 Series Convertible also brings significant improvements in passenger space and access, acoustic comfort, style, dynamism and equipment, while the ConnectedDrive services for the first time include wireless updating of navigation data.
The electrically operated folding soft top lowers or raises in just 20 seconds at the touch of a button, and can be carried out at speeds of just over 30mph. Additional insulation in the skin of the soft-top improves acoustic comfort, with a 4db noise reduction, and adds to the year-round usability of the car. Improved aerodynamics, with a Cd of just 0.31, also helps to make the cabin quieter. An easier-to-use optional wind deflector provides greater protection against turbulence when travelling top-down.
The four-seat interior, with folding rear bench, provides greater space and a more intense open-top driving experience, placing the occupants in a typical BMW set-back position. Rear access benefits from an 11mm wider aperture when the front seats are tilted forwards. Large door pockets, a spacious glovebox, a central storage compartment and two cup holders provide improved in-cabin storage.
The track widths of the BMW 2 Series Convertible are larger than those of its predecessor, by 41mm at the front and 43mm at the rear, so that the widest part of the car is the rear wheel arch area. This emphasises the greater dynamism of the new model and its unique-in-class rear-drive layout. Horizontal lines at the rear also hint at the car’s wider stance. The rear lights extend into the side panels and feature familiar BMW L-shaped LED light bars. At the sides, a slightly rising shoulder line, swage lines running through the door handles and character lines from the doors and side skirts to the rear panels all point to the car’s sporty, rear-wheel-drive layout.
A more rigid body and advanced new safety features for greater protection
The BMW 2 Series Convertible delivers enhanced safety for occupants and pedestrians compared with the previous model through a combination of a more rigid body and advanced safety features. Torsional stiffness has been raised by 20 per cent and bending stiffness is 10 per cent higher, despite a decrease in body weight, thanks to extensive use of high- and ultra-high-strength steels.
The A-pillars with strengthening elements and joints made from hot-formed steel combine with the aluminium bars hidden behind the rear seats to form a survival space for occupants in the event of a roll-over accident. The roll-over bars are triggered automatically in fractions of a second if the car’s electronic sensors detect any risk. Strong supporting structures, precisely defined load paths, large deformation zones and intelligent restraint systems ensure that the BMW 2 Series Convertible meets or surpasses safety requirements around the world. Meanwhile, an active bonnet which rises at the rear and contains special deformation areas provides optimum pedestrian protection.
Greater performance and dynamism with improved efficiency
Four BMW TwinPower Turbo engines featuring a suite of EfficientDynamics technologies endow the BMW 2 Series Convertible with superior performance to its predecessor, with an average 18 per cent improvement in fuel efficiency and lower CO2 emissions. The engines include a new 2.0-litre diesel for the 220d and, for the first time in a BMW convertible, an M Performance power unit for the M235i. There are also two 2.0-litre petrol engines available, the 220i and 228i. All are more powerful than the engines in the previous model and meet EU6 emissions standards.
The new 2.0-litre diesel engine develops 14hp and 50Nm of torque more than the previous unit, with greater efficiency. The combined fuel economy is 60.1mpg with the six-speed manual transmission or 64.2mpg with the eight-speed automatic gearbox which is optional on every model, while the respective CO2 emissions are 124g/km and 116g/km. It features an aluminium crankcase with thermally joined liners to reduce internal friction, and balancer shafts to eliminate vibrations. An enhanced turbocharger and an improved common-rail direct-injection system operating at up to 2,000 bar raise efficiency, and the engine is also lighter and quieter than its predecessor.
The M Performance 3.0-litre six-cylinder engine in the M235i develops 326hp and 450Nm of torque from only 1,300rpm with the aid of twin-scroll turbocharging, high-precision centrally positioned multi-hole direct injectors, VALVETRONIC variable valve timing and Double-VANOS variable camshaft timing. The result is an infectious cocktail of high-revving ability, responsive power, instantaneous torque and sports car performance with the utmost efficiency. Acceleration from zero to 62mph is achieved in 5.2 seconds with the manual gearbox and 5.0 seconds with the automatic, yet combined fuel economy is 33.2mpg in the manual and 35.8mpg in the automatic, while CO2 emissions are 199g/km and 184g/km respectively.
The longer wheelbase, increased track widths and stiffer body of the BMW 2 Series Convertible, allied to the latest driver assistance systems, ensure that the driving experience has been raised to even greater levels. The car has the typical sporty agility of a rear-drive BMW with an ideal front-to-rear weight distribution, combined with exceptional comfort. The double-joint tie-bar front suspension with spring struts and five-link rear axle have been precision-tuned for the BMW 2 Series Convertible.
The standard electronic assistance systems include Dynamic Stability Control; incorporating Anti-lock Braking, Dynamic Traction Control, Cornering Brake Control and Dynamic Brake Control. These are supported by Brake Assist, Fading Compensation, Brake Drying, the Start-Off Assistant and the Active Differential Brake. The car can also be specified with either M Sport or Adaptive M Sport suspension and M Sport braking system.
The M Sport suspension and braking system, with model-specific tuning, are standard on the 228i and M235i, which also has custom-tuned Variable Sport steering. The suspension set-up and damping of the range-topping model takes into account, not only its exceptional performance, but also the characteristics introduced by its soft roof. Options include a BMW M Performance limited-slip differential.
ConnectedDrive now with free wireless navigation updates
The BMW 2 Series Convertible can be fully connected with the outside world through a wide range of standard-fit and optional ConnectedDrive features. They include, for the first time on any BMW, a new Professional navigation system which updates navigation data free and wirelessly through the built-in SIM card. This is capable of supporting the LTE (Long Term Evolution) wireless standard, which is up to five times faster than 3G.
Every BMW 2 Series Convertible comes with Bluetooth hands-free telephone connectivity with audio streaming and a USB interface, a DAB tuner, BMW Emergency Call and BMW TeleServices. These can be supplemented with BMW Navigation or Professional multimedia system, Internet connectivity, BMW Online Services, Online Entertainment, Real Time Traffic Information, enhanced Bluetooth with Voice Control, Remote Services and Information Plus.
Customers can also specify the Driving Assistant with camera-based Lane Change and Lane Departure warning systems. It also features Attention Assistant to alert a potentially drowsy driver. Collision Warning primes the brakes and alerts the driver if the 2 Series Convertible gets too close to the car in front. Rear Park Distance Control is standard, and can be supported with Park Distance Control at the front as part of the Driver Comfort package. A Reversing Assist camera is also offered.
M Sport versions have High-gloss Shadowline exterior trim, Aluminium Hexagon trim with Estoril Blue accents, extra-wide High-gloss Black kidney grille slats, a Sport instrument cluster, dual chrome exhaust tailpipes, M Sport suspension, an M Sport multi-function leather steering wheel, M aerodynamic body styling and M door sill finishers. There is also an M Sport Plus package of Ferric Grey 18-inch alloy wheels, headlight wash, harman/kardon loudspeaker system, M Sport brakes, Xenon headlamps and a grey windscreen shade band.
Last but not least, the unique specification of the M235i includes 18-inch double-spoke alloy wheels, Ferric Grey air blades and mirror caps, dual-zone air conditioning, Dakota leather upholstery, Extended Lighting and Storage, M Sport suspension and braking, an M rear spoiler and unique M logos on the wings.
