BMW has announced new models in its mid-sized executive car line-up, including a new 520d EfficientDynamics model capable of 62.8mpg.
Aimed at the business market, the new 520d ED, as it will be known, is around 10 per cent more fuel efficient than the best of its rivals, matching the hypermiling fuel consumption figure with CO2 emissions of just 119g/km. Compare this with 149g/km for the Jaguar XF 2.2 diesel and the Volvo S80 D5 at 129g/km, both of which we’ve detailed in the last week. Not even Audi or Mercedes-Benz can come close.
In spite of all this green speak, the new model still has the 184bhp of the previous 520d, can reach 144mph and sprint from 0-62mph in 8.2 seconds. So how do they do it? A standard stop/start system, a gear shift indicator to prompt fuel efficient driving, Brake Energy Regeneration, Active Aerodynamics, low rolling resistance tyres on streamlined alloy wheels and a longer final drive ratio to reduce engine revs at motorway speeds.
The 520d ED also comes with BMW’s new ECO-PRO Mode. A driver-activated switch promotes economical and comfortable driving at low speeds by adjusting the engine mapping, throttle sensitivity, automatic gearshift points (when fitted with the auto box) and the amount of power consumed by electrical ancillaries including climate control and heated seats.
It’s on sale in September as a saloon only (no Touring estate version) with a price of £30,435 on the road.
At the same time, BMW is also adding three other new models to the range: a new 520i, 528i and a 525d.
Contrary to what the badges on the boot may say, both petrol engined cars have a four cylinder 2.0 litre with twin-scroll supercharger, an engine that recently debuted in the X3.
The 520i has 184bhp, a top speed of 141mph and does the 0-62mph dash in 7.9 seconds. Combined mpg is 41.5 (44.1 for the optional automatic) with CO2 emissions of 157g/km (which the auto betters with 149g/km). It will be priced from £31,190, cheaper by £1,500 than the saloon model it replaces. A Touring estate model is priced at £33,615.
The 528i is powered by the same engine but with tweaks to the fuel injection system and more boost through the turbo, hitting an impressive 245bhp and lifting the stop speed to an electronically limited 155mph; the 0-62mph time is 6.2 seconds. And there appears to be no price to pay at the pumps for the extra performance, as BMW is claiming the same mpg as the 520i at 41.5 (43.5 for the auto). CO2 levels are 159g/km (153g/km automatic). But we have a suspicion these published figures from BMW are for the 328i instead.
Finally, in the 525d, a new four cylinder 2.0 litre twin-turbo diesel engine replaces the single turbo six cylinder 3.0 litre unit. The new engine generates 218hp and is claimed to improve acceleration while reducing fuel consumption by up to 20 per cent. The BMW 525d SE Saloon costs from £35,135 on the road but can also be had as a Touring estate for £37,560.
