The trendsetters are entering their second generation: Starting in mid-October, the BMW 730d and BMW 740d will supplement the model range in the 7 Series introduced recently. Featuring the latest common rail technology, these new models are continuing the concept of success already defined by BMW: Power, performance and agility, on the one hand, coupled with comfort and economy, on the other, have given the diesel a genuine breakthrough in the luxury performance range, making the BMW 7 Series the benchmark in the world of high-tech self-igniting power units. Led by the 740d as the world's first 8-cylinder direct-injection diesel saloon, the diesel-powered BMW 7 Series has progressed very quickly from the connoisseur's choice to a genuine best seller, accounting for a model mix share between 35 and 85 per cent in the major European diesel markets.
It is only obvious, therefore, that customers expect a great deal of the new 7 Series diesel. And it is just as obvious that both models will more than fulfil these expectations: Featuring second-generation common rail fuel injection and boasting further improvements in many areas, both the six- and 8-cylinder power units offer significant improvements. Maximum output of the BMW 730d is now 160 kW or 218 bhp at 4,000 rpm, maximum torque is 500 Nm or 369 lb-ft between 2,000 and 2,750 rpm. The BMW 740d, in turn, develops maximum output of 190 kW or 258 bhp at 4,000 rpm and maximum torque of 600 Nm or 442 lb-ft between 1,900 and 2,500 rpm.
In the interest of optimum and highly efficient power transmission combined with excellent gearshift comfort, both diesels come for the first time in the world with the six-speed automatic transmission which already made its debut in the 735i and 745i, receiving excellent grades in every respect.
The result is truly outstanding performance on the road: The BMW 730d accelerates from 0-100 km/h in 8.0 seconds and has a top speed of 235 km/h or 146 mph. The 740d accelerates to 100 km/h in 7.4 seconds and reaches a top speed of 250 km/h or 155 mph. And in this process the new diesel-powered 7 Series make do with fuel consumption of only 8.5 and, respectively, 9.7 litres/100 km in the EU cycle (33.2 and, respectively, 29.1 mpg Imp).
The significant progress offered by both engines will be felt by the customer particularly in everyday motoring: The engines are once again quieter and more comfortable, they are significantly more dynamic in their performance, and thanks to the combination with BMW's outstanding six-speed automatic transmission, they respond to every movement of the gas pedal with out- standing agility and performance. In a nutshell, therefore, the new 7 Series diesels rank right at the top in their competition segments, once again impressively confirming BMW's competence in diesel technology.
Introducing the 730d and 740d, BMW is now offering all the features of the innovative 7 Series - whether standard or optional - also in the diesel segment. As an example, the all-aluminium chassis is also available with BMW's unique Dynamic Drive active suspension as well as continuously adjustable Electronic Damper Control (EDC) featured for the first time in the market and pneumatic suspension with automatic self-levelling at the rear. In their wide range of standard features both diesel models largely correspond to the 8-cylinder petrol engine versions, and both models come exclusively with the standard wheelbase of the 7 Series.Published 27 September 2002
