As expected, the brand new 2014 BMW 4 Series Convertible was launched with the same engines as its Coupe brother, the main differences being in the performance numbers.
So, the entry level model on petrol will be the 428i, fitted with a 2-liter turbocharged 4-cylinder engine that makes 245 HP and 350 Nm (258 lb-ft) of torque. The 0-100 km/h (62 mph) sprint is done in 6.4 seconds and the top speed is limited to 250 km/h (155 mph).
Fuel consumption is rated at 6.8 l/100 km (34 mpg) for the manual 6-speed transmission and 6.6 l/100km (35.6 mpg) for the automatic 8-speed. Furthermore, all engines are EU6 compliant, this one releasing 159 grams of CO2 into the atmosphere for each km.
The 435i will use the classic 3-liter turbo 6-cylinder N55 engine that makes 306 HP and 400 Nm (300 lb-ft) of torque. Performances are better than expected, 0-62 mph (100 km/h) taking just 5.5 seconds for the automatic and 5.6 for the manual transmission.
Fuel efficiency has been rated at a combined 7.5 l/100 km (31.3 mpg) for the auto and 8.1 l/100 km (29 mpg) for the manual and CO2 emissions sit around 176 grams of CO2 per km.
Last but not least, we have a diesel too, the 420d model, using a 2-liter turbo diesel unit that makes 184 HP and 380 Nm (280 lb-ft) of torque. This model is by far the most efficient, taking up just 4.8 l/100km (49 mpg) with the automatic and 5.1 l/100km (46 mpg) for the manual gearbox.
Performance is not bad either, getting to 100 km/h (62 mph) in 8.2 seconds for both transmission and emitting just 127 grams of CO2 per 1 km. Most likely, the 420d won’t make it to the US at first, the best choice out there remaining the 428i for both performance and efficiency.
