The European-specd BMW 3 Series and 4 Series models are getting new and refreshed powerplants this Spring.

The BMW 316d Sedan and the BMW 316d Touring will be powered in future by a four-cylinder diesel power unit from the current BMW Group engine family. The generation change comes with an increase in power and efficiency. The new 2-litre engine delivers a maximum output of 85 kW/116 hp, a 10 Nm increase in maximum torque to 270 Nm and can be optionally combined with the 8-speed Steptronic transmission.

This engine allows the Sedan to accelerate from 0 to 100 km/h in 10.7 seconds (automatic: 10.6 seconds) and the Touring model in 11.2 seconds (11.1 seconds). In conjunction with the manual transmission or the 8-speed Steptronic transmission, fuel consumption and emission levels have been lowered to between 4.3 and 3.9 litres per 100 km and between 113 and 102 g/km for the BMW 316d Sedan and to between 4.6 and 4.1 litres/100 km and 120 to 109 grams per km for the BMW 316d Touring respectively (figures as per EU test cycle depending on selected tyre size).

Premiere of the BMW 418d Coupe, greater power and efficiency for the BMW 420d Coupe and the BMW 420d Gran Coupe.

The introduction of additional engines of the latest generation brings added driving pleasure and further optimised efficiency also to the BMW 4 Series. March 2015 will witness the market launch of the entry-level version of the BMW 418d Coupe, the four-cylinder engine of which will be the fifth diesel power plant to be offered for the BMW 4 Series. The 2-litre engine delivers a maximum power output of 110 kW/150 hp and a maximum torque of 320 Nm. The new BMW 418d Coupe sprints from 0 to 100 km/h in 8.6 seconds with either the standard 6-speed manual transmission or the optional 8-speed transmission. In spite of the car’s sporty character, average fuel consumption is between 4.5 and 4.2 litres/100 km (automatic: 4.4 – 4.1 litres/100 km) and CO2 emission levels range from 118 to 110 g/km (117 – 109 g/km; figures as per EU test cycle depending on selected tyre size).

A further new 2-litre diesel engine with more power and optimised efficiency will in future drive the models BMW 420d Coupe, BMW 420d xDrive Coupe, BMW 420d Gran Coupe and BMW 420d xDrive Gran Coupe. It generates an output of 140 kW/190 hp, an increase of 5 kW, delivers a maximum torque of 400 Nm (+20 Nm) and can be optionally combined with the 8-speed Steptronic transmission. As a result, the relation between sportiness and efficiency reaches an even higher level. The BMW 420d Coupe sprints from a standstill to 100 km in 7.3 seconds (automatic: 7.1 seconds), the BMW 420d xDrive Coupe in just 7.4 seconds (7.2 seconds). Fuel consumption and CO2 emission levels are now between 4.5 and 4.2 litres/100 km and between 119 and 111 g/km for the BMW 420d Coupe (automatic: 4.3 – 4.0 litres/100 km, 114 – 106 g/km) and between 4.7 and 4.4 litres/100 km and between 125 and 117 grams per km for the BMW 420d xDrive Coupe (automatic: 4.7 – 4.4 litres/100 km, 125 – 117 g/km; figures as per EU test cycle depending on selected tyre size).

The BMW 420d Gran Coupe now accelerates from 0 to 100 km/h in 7.5 seconds (automatic: 7.3 seconds). In conjunction with the intelligent four-wheel drive system xDrive this figure is 7.6 seconds (7.4 seconds). Resulting from the new engine’s optimised level of efficiency, the BMW 420d Gran Coupe has an average fuel consumption of 4.5 to 4.2 litres/100 km (automatic: 4.3 – 4.0 litres/100 km) and CO2 emissions ranging from 119 to 111 g/km (114 – 106 g/km). The corresponding values for the BMW 420d xDrive Gran Coupe are 4.9 to 4.6 litres/100 km (automatic: 4.8 – 4.5 litres/100 km) and 129 to 121 g/km (126 – 118 g/km; figures as per EU test cycle depending on selected tyre size).

In addition to the revised engines, new exhaust systems featuring redesigned tailpipes are also being introduced to the BMW 4 Series. The cross section of the exhaust tailpipe for the BMW 418d Coupe is 75 mm.

The models of the BMW 4 Series are powered by a 140 kW/190 hp diesel engine and are equipped with twin-flow tailpipes, each with a diameter of 70 mm.
