The BMW 730iL (E38) was a long-wheelbase variant of the E38 7 Series, produced between 1994 and 1996. Positioned as an entry-level offering within the flagship 7 Series range, the 730iL aimed to provide a luxurious experience with a more accessible price point compared to the higher-powered 740iL and 750iL models. The “L” designation signified the extended wheelbase, offering increased rear passenger legroom – a key selling point in markets where chauffeur-driven luxury sedans were popular. This model primarily targeted buyers seeking a comfortable, prestigious vehicle with a focus on rear passenger comfort rather than outright performance.

Powertrain & Engine Architecture
The 730iL was powered by the BMW M60B30 engine, a 3.0-liter naturally aspirated V8. This engine was part of BMW’s first generation of V8 engines after a long hiatus, and represented a significant engineering achievement. It featured a 60-degree V-angle, all-aluminum construction, and double overhead camshafts (DOHC) with four valves per cylinder. The M60B30 utilized Bosch Motronic 1.7 engine management, controlling multi-port fuel injection and ignition timing. The engine produced 218 horsepower at 5800 rpm and 290 Nm (213.89 lb-ft) of torque at 4500 rpm. Paired with the engine was a 5-speed automatic transmission marketed as “Steptronic,” which offered both fully automatic operation and a manual shift mode for greater driver control. The Steptronic transmission was a significant advancement for its time, providing smoother shifts and improved fuel efficiency compared to earlier automatic transmissions.
Driving Characteristics
The 730iL, with its 3.0-liter V8 and automatic transmission, offered a smooth and refined driving experience. Acceleration from 0 to 60 mph took approximately 9.2 seconds, and top speed was limited to 145.4 mph. While not as quick as the 740iL or 750iL, the 730iL provided adequate power for comfortable cruising and overtaking. The Steptronic transmission, while offering a manual mode, was primarily geared towards smooth, effortless shifts. The gear ratios were optimized for fuel economy and relaxed driving, rather than aggressive performance. Compared to the manual transmission options available in other 7 Series models, the 730iL automatic prioritized comfort and ease of use.
Equipment & Trim Levels
The 730iL came standard with a comprehensive list of luxury features, befitting its flagship status. Standard equipment included leather upholstery, power-adjustable front seats with memory function, automatic climate control, a premium sound system, and a sunroof. The extended wheelbase provided significantly more rear legroom than the standard 7 Series, making it ideal for chauffeured transport. Optional extras included rear seat entertainment systems, upgraded leather options, and various cosmetic enhancements. The interior trim typically featured wood accents, and the dashboard layout was designed for both elegance and functionality.
Chassis & Braking
The E38 7 Series featured an independent suspension system with wishbone front suspension and an inclined lever rear suspension. This setup provided a comfortable ride and good handling characteristics. The 730iL was equipped with ventilated disc brakes at the front and solid disc brakes at the rear. Anti-lock braking system (ABS) was standard, enhancing safety and stability during braking. The steering system was a rack-and-pinion setup with hydraulic power assistance, providing precise and responsive steering feel. The 730iL’s suspension was tuned for comfort, prioritizing a smooth ride over sporty handling.
Market Reception & Comparison
The 730iL was generally well-received by automotive critics, who praised its luxurious interior, comfortable ride, and refined driving experience. However, some critics noted that its performance was not as exhilarating as the higher-powered 7 Series models. Fuel economy was considered reasonable for a V8-powered luxury sedan, averaging around 22.4 US mpg in combined driving. Compared to the 740iL, the 730iL offered a more affordable entry point into the 7 Series range, but at the expense of some performance. The 730iL also offered a different driving experience than the diesel-powered 730d, which prioritized fuel efficiency and low-end torque.
Legacy
The E38 730iL, while not the most powerful variant of the E38 generation, remains a desirable classic car. The M60B30 engine is known for its reliability and smooth operation, although maintenance can be expensive due to its complexity. The Steptronic transmission, while advanced for its time, can require specialized servicing. Today, well-maintained examples of the 730iL are sought after by collectors and enthusiasts who appreciate its blend of luxury, comfort, and classic BMW engineering. The extended wheelbase and luxurious interior continue to make it a compelling option for those seeking a comfortable and prestigious classic sedan.
