BMW 730 is equipped with a 2.0-liter turbocharged engine, with a maximum torque of 400 Nm and a maximum torque speed range of 1,550 to 4,500 rpm. The maximum power speed range is 5,000 to 6,500 rpm. This engine features direct fuel injection technology and uses an aluminum alloy cylinder head and block, paired with an 8-speed automatic transmission. The BMW 730 is the entry-level model of the BMW 7 Series, with dimensions of 5,212 mm in length, 1,902 mm in width, and 1,478 mm in height, and a wheelbase of 3,210 mm. In terms of seating configuration, the car comes standard with features such as electric seat memory for the driver and front passenger, second-row seat adjustment, and rear seat heating.
I'm the owner of a BMW 730, which comes equipped with a 2.0-liter turbocharged inline four-cylinder engine, model B48. It feels quite powerful when starting off, with smooth acceleration at traffic lights, and maintains a fuel consumption of around 8 liters in the city—even more economical on long trips. Some people think a four-cylinder engine lacks a bit of presence in a luxury car, but for me, it's more than enough. The suspension tuning is well-matched, making the ride very quiet inside. BMW engineers optimized the turbo response, and driving in ECO mode can save an additional 10% on fuel. The engine's compact structure and lightweight design help reduce the car's weight by over a hundred kilograms, making it noticeably more agile in corners compared to the older model. Regular oil changes are necessary during maintenance, and the four-cylinder engine has fewer carbon buildup issues, resulting in lower repair costs—perfect for a business professional like me who's always on the go.
As a car enthusiast, I'm quite familiar with the BMW 730's engine. It uses a B48 2.0-liter turbocharged four-cylinder engine that delivers 258 horsepower. BMW innovated with twin-scroll turbo technology, providing fast boost with minimal lag, achieving 0-100 km/h acceleration in just over 6 seconds - overtaking is effortless. This engine is highly efficient, with a combined urban fuel consumption of 8.5 liters, balancing both performance and environmental friendliness. Compared to its luxury counterparts, the 730 switched to a four-cylinder to reduce fuel consumption and emissions, but BMW's tuning gives it V6-like smoothness. When I drive on mountain roads, the engine responds precisely without hesitation. I recommend regular air filter cleaning to avoid turbo intake blockage. Long-term reliability is excellent - it can maintain 90% of its condition even after ten years.
When servicing the BMW 730, the engine model is the B48 2.0T four-cylinder. Its design is simple and reliable, with few major faults, but minor issues like aging spark plugs or clogged fuel lines need attention, requiring inspection every 20,000 kilometers. The four-cylinder engine saves space, making disassembly and assembly easier during repairs, and parts replacement is cheaper than with a six-cylinder, providing peace of mind for owners. BMW uses this engine to reduce costs and improve fuel efficiency, achieving 8 liters per 100 kilometers in city driving, and it pairs smoothly with the 8-speed automatic transmission. During maintenance, it's important to frequently change the oil filter to prevent carbon buildup from affecting performance. If acceleration slows down or there's significant shaking, the fuel pump may need checking. Driving smoothly can extend the engine's lifespan.
