Buyers of BMW’s new 730d luxury saloon, which goes on sale this month, will benefit from fuel consumption that is identical to many small four-cylinder sedans and hatchbacks.
In a pioneering breakthrough, the 730d also becomes the first, and only, car in the upper luxury sedan segment that emits less than 200 grams of CO2 per kilometre (192 g/km).
This puts it ahead of hybrid and other diesel competitors in the segment which all use more fuel and emit greater volumes of CO2.
“Buyers of large premium saloons can now make an even greater contribution to lowering CO2 emissions thanks to the arrival of the new 730d,” said BMW’s general manager of marketing, Tom Noble.
The new 730d consumes no more fuel, on the official combined cycle, than much smaller four-cylinder cars such as the manual 1.8-litre Holden Astra CD, the manual 1.6-litre Skoda Roomster, or the automatic 1.8-litre Honda Civic VTi.
The 730d’s official combined fuel usage – 7.2 litres per 100 kilometres – is also identical to smaller cars such as the 2.0-litre Mercedes-Benz A200 and 1.8-litre multitronic Audi A4 1.8 TFSI.
“It’s not often a luxurious five-seater saloon is compared with smaller four-cylinder cars, but in terms of fuel consumption the 730d demonstrates the remarkable achievement of BMW’s EfficientDynamics programme,” said Noble.
The diesel-powered 7 Series – the first ever offered in Australia – also delivers a credible alternative to less fuel-efficient hybrid-powered vehicles in the upper luxury segment, which consume almost thirty per cent more fuel than the 730d.
The brand new turbocharged all-alloy straight six-cylinder engine in the 730d produces 180 kW of power and 540 Nm of torque, accelerating the car from 0-100 km/h in just 7.2 seconds. In addition it complies with the most stringent Euro 5 European emissions legislation.
The straight-six engine features an aluminium block, third generation common rail direct injection with piezo injectors, and a maximum injection pressure of 1,800 bar. The turbo charger has variable turbo geometry and a diesel particle filter and an oxidation catalyst are fitted as standard.
Active control of the air flaps in the radiator grille and the brake air shafts contribute to the car’s overall efficiency. The air flaps are opened only when the engine requires additional cooling air, while remaining closed when not required in order to optimise the car’s aerodynamics.
Intelligent energy management (Brake Energy Regeneration) serves to efficiently generate electric power for the car’s on-board network. To provide this effect, the alternator is activated only when the engine is in overrun and when applying the brakes, thus relieving the engine of the usual loads and power uptake.
Standard equipment levels of the new BMW 730d are the same as the recently released 740i, including features such as Head Up Display, rear view camera, metallic paint, 18-inch light-alloy wheels, Dynamic Driving Control, Brake Energy Regeneration, adaptive headlights, heated and ventilated front seats, sunroof, automatic boot operation, soft close function on all doors, television tuner, voice recognition, and 6-stack DVD player.
The new 7 Series features a host of cutting edge new technologies, many of which are not offered by key rivals, revealing that ingenious ideas which provide pioneering solutions for customers are hallmarks of BMW.
For example Head-Up Display, which allows drivers to keep their eyes on the road thanks to key driving information presented directly in their line of sight, is standard on the 730d and not yet available on competitor vehicles.
High Beam Assist, which relieves drivers of the need to constantly adjust their headlights when driving at night, is also standard and exclusive to the new 730d in the upper luxury sedan segment.
At the same time, BMW’s engineers are continuing to develop other customer benefits, many of which are exclusive to the 7 Series in this segment.
The new pedestrian recognition feature of BMW’s optional Night Vision system is unique in this segment. It ensures safer and more comfortable driving at night. At 100 km/h, the camera can provide seven seconds warning of potential hazards, more than enough time to take evasive action. The panning function turns the camera image when the vehicle is corning, allowing driver to see around corners in the dark.
Another customer benefit, available exclusively to 7 Series buyers in this segment, is the new Side View camera. Utilising two cameras in the front wheel arches, the driver can easily monitor crosswise traffic when edging out of a driveway or when parking in confined spaces.
Also available on the 730d – and not yet offered by rivals in this class – is a feature which detects any unintentional drifting off course, perhaps when a driver is fatigued. The Lane Departure Warning system, which is able to look 50 metres ahead and can be used at night, vibrates the steering wheel to alert the driver.
In addition, and for the first time in a BMW, radar sensors at the rear of the car monitor traffic in adjacent lanes allowing drivers to overtake (or change lanes) in greater safety. The optional Lange Change Warning system illuminates a triangle symbol on the base of the exterior mirror when there is another car in a critical range. A discreet vibration of the steering wheel also cautions against making the manoeuvre.
Highlighting its exclusive character, the BMW 730d is also equipped standard with soft close doors. This feature ensures that the doors are securely closed with a minimum of exertion and without unpleasant noise. This appreciable customer benefit – standard on the 730d – is only available as a cost option on its key diesel rivals. Similarly, a rear view camera – standard on the 730d – is a cost option on its immediate diesel competitors.
In another world first, the 7 Series owner has all the information usually found in a printed handbook also stored electronically in their car, uniquely structured to reflect exactly the features and specifications of their vehicle. Owners can search by pictures (imagine painting by numbers), topics, or simply select the “option” any time. The on-line version of the handbook also contains slide shows on key new features.
The new 730d – the first diesel powered 7 Series sold in Australia – will right from the start establish itself at the top of the performance pecking order. Despite class leading fuel consumption, the new 730d will accelerate from zero to 100 km/h faster and develop more power than its immediate 3.0-litre diesel competitors.
“For many customers the performance and unrivalled efficiency of the new BMW 730d will be the prime attraction, coupled with the sure-footed and dynamic driving experience,” said BMW’s general manager of marketing, Tom Noble.
The newest addition to the model line-up is the first 7 Series to be offered with diesel power in Australia. In Europe, the predecessor 730d model was the biggest seller, underlining its wide appeal among the most discerning buyers.
The 730d uses a new generation turbo-diesel also fitted to the new 330d Sedan. It is a straight-six featuring an aluminium block, third generation common-rail direct injection with piezo injectors, and a maximum injection pressure of 1,800 bar. The turbo charger has variable turbo geometry and a diesel particle filter and an oxidation catalyst are fitted as standard.
The 730d engine generates 180 kW of power at 4,000 rpm and 540 Nm of torque between 1,750-3,000 rpm. As a result, the BMW 730d accelerates from 0-100 km/h in 7.2 seconds, and uses just 7.2 l/100km of fuel, emitting only 192 g/km of CO2, making it the most economical car in its class. This engine is 10 kW more powerful, 5 kg lighter and uses 10 percent less diesel than its predecessor and is the first car in the upper luxury sedan segment to emit less than 200 grams of CO2 per kilometre.
The new 3.0 litre turbo diesel six cylinder engine delivers performance akin to a V8 engine, but with the fuel economy of some four cylinder engines housed in much smaller bodies. Thanks to 180kW of power, available at 4,000 rpm and maximum torque of 540 Nm available across an enduring plateau extending from 1,750-3,000 rpm, the first ever diesel 7 Series model delivers effortless, seamless performance.
Like all of the 7 Series models the BMW 730d is mated to a six-speed automatic transmission equipped with optimised gearshift dynamics for faster shifting, improved shift comfort, reduced fuel consumption, and are controlled via the electronic gear selector.
In keeping with BMW’s EfficientDynamics strategy the BMW 730d is equipped with a host of efficiency measures including active air vent control, Brake Energy Regeneration, common-rail injection and optimised weight saving.
Load bearing body components are steel, while the roof, doors, bonnet and side panels are made of aluminium. The alloy roof alone saves 7 kg, and the doors save 22 kg. The aluminium pressure-cast suspension supports at the front, and a final drive with aluminium housing all work towards keeping overall weight as low as possible.
The BMW 7 Series is renowned for its dynamic on-road performance, and the 730d is certain to offer unrivalled enjoyment behind the wheel for the sporting driver.
The all-new suspension optimises ride and handling with a particular accent on comfort. The new BMW 7 Series is the first BMW Sedan with a double-wishbone front axle and the exclusive BMW integral V rear axle, made largely of aluminium.
Hydraulic rack-and-pinion steering with an on-demand steering assistance pump joins the world debut of optional Integral Active Steering, a combination of Active Steering on the front axle and speed-related rear-wheel steering.
Extending the performance envelope are new driver assistance features such as Dynamic Damping Control including Dynamic Driving Control which are standard.
The dampers, gearshift dynamics, as well as the throttle and steering assistance map are varied by the Dynamic Driving Control button on the centre console. This offers the choice of COMFORT, NORMAL, SPORT and SPORT PLUS settings.
Dynamic Damping Control allows infinitely variable control of the damping effort for compression and rebound, across all settings, enabling occupants to be perfectly insulated from road harshness or uneven surfaces. This allows a truly unique combination of firm suspension setup on the one hand, and a comfortable response to bumps on the other, and becomes the benchmark in suspension ride and comfort in this class.
A special traction mode and SPORTS+ setting with reduced or deactivated DSC control is available for drivers wishing to experience a particularly sporting style of motoring.
In Australia, customers are offered the following features as standard on the new BMW 730d (note specification is directly aligned to the 740i): Head-Up Display, High Beam Assistant, Adaptive bi-Xenon headlights with daytime running function, variable headlight beam distribution for better illumination around bends, including automatic turning lights, Automatic Variable Light technology (beam throw control with country / highway lights), Rear View Camera, and Cruise Control with Brake function.
The new BMW 730d will go on sale this month with a manufacturer’s list price from $198,800*, which is $4,200 less than the similar equipped BMW 740i.
