German carmaker BMW has always been about power and luxury: but the debut of its new 4-Series Coupe line-up suggests a strong focus on efficiency.
The two-door model is set to be available with a host of engines: a six-cylinder in-line petrol engine for the BMW 435i Coupe; a four-cylinder petrol engine for the BMW 428i Coupe; and a four-cylinder diesel in the BMW 420d Coupe.
Each engine will benefit from the BMW TwinPower Turbo technology that is meant to offer impressive performance - outputs range from 135kW/184hp to 225kW/306hp. However, the vehicles have also been optimised for fuel economy with lightweight construction; and a focus on aerodynamics including both air breathers and air curtains. In addition, each vehicle will also boast a host of EfficientDynamics technologies including brake energy regeneration; optimum shift indicator; and auto start-stop.
Every model in the BMW 4 Series Coupe line-up will also include ECO PRO mode which has the potential to slash fuel use: potentially by as much as 20 per cent.
The diesel models include common rail direct injection; all-aluminium construction for higher torque; and turbocharging. The diesel engines will come with advanced BluePerformance technology that combines a diesel particulate filter with oxidation catalytic converter and nitrogen oxide storage catalyst.
Let's take a look at the statistics for each model:
- BMW 420d Coupe: Offers a maximum output of 135kW/184hp at 4,000rpm with peak torque at 380Nm. It can race from 0-62mph in 7.5seconds with a top speed of 149mph. Its fuel consumption is 49-50mpg and CO2 emissions range from 124-126g/km.
- BMW 428i Coupe: Generates 180kW/245hp at 5,000-6,500rpm. It can accelerate from 0-62mph in 5.9 seconds with a top speed of 155mph. Its fuel consumption ranges from 35.1-35.6mpg with CO2 emissions at 154-156g/km.
- BMW 435i Coupe: Maximum output is 225kW/306hp from 5,800-6,000rpm with peak torque at 400Nm. It can accelerate from 0-62mph in 5.4seconds; top speed is limited to 155mph; average fuel consumption is 29-30mpg; and CO2 emissions range from 185-189g/km.
It is expected that the line-up will be furthered later in the year with the addition of the BMW 430d Coupe, BMW 435d Coupe, the BMW 420i Coupe and two xDrive options.
