730 is equipped with a 4-cylinder engine. The BMW 730 belongs to the BMW 7 Series. Below are detailed introductions about the BMW 7 Series: 1. Overview: The BMW 7 Series is BMW's top-tier luxury sedan series, featuring a 4-door sedan body style and a front-engine, rear-wheel-drive layout. The BMW 7 Series is the flagship model of BMW automobiles. It is exclusively produced in Germany and replaced the previous generation model, BMW New Six, in 1977. 2. Others: The vehicle dimensions are 5212mm × 1902mm × 1478mm. The fuel tank capacity is 82L. The standard seating capacity is 5. The top speed is 245km/h. The seat material is genuine leather. The acceleration time ranges from 4.6 to 8.3 seconds (0-100km/h). The braking system uses ventilated discs.

Last time at a track day, I was chatting with some buddies who are into car modifications about Motorsport – that's my area of expertise. The M Division doesn't have standalone series numbers; it's BMW's performance designation. For example, the upgraded version of the regular 3 Series is called the M3, and the high-performance version of the 5 Series is the M5. The current street versions of the M3/M4 belong to the G chassis series, instantly recognizable by their signature quad exhaust and carbon fiber roof. Last year, I test-drove a friend's M2 Competition – don't let its compact size fool you, the S58 engine delivers 460 horsepower, even more aggressive than the older M4. By the way, this year's newly launched XM hybrid marks the M Division's first independently designed SUV, though its taillight design has sparked quite some debate.

Our auto repair shop frequently handles M series maintenance, and customers often ask this question. Actually, checking the vehicle model is the most accurate method: the tail badge M340i belongs to the 3 Series performance version, while true Motorsport models are identified by pure letter M badges. For example, the F90 generation M5 uses a 4.4T V8 engine, and the new XM combines a V8 with an electric motor to achieve 748 horsepower. From a mechanical perspective, M series all use reinforced chassis codes. Even the engine mounts on current G80/G82 M3/M4 models are specially designed, and the rear axle widebody requires replacing the entire fender set. For those interested in classic cars, note that while the E30 M3 is iconic, its parts are notoriously hard to find.

My team coach has driven three generations of M3. Motorsport comes in three forms: the most accessible is the M Performance package version (like the M240i), the intermediate is the true performance M Power cars (M4), and the top tier is the M4 GT3 race car. Among the current street M models, the G87 M2 released two years ago is the most agile, but for pure driving pleasure, the manual transmission M3 Touring takes the crown. Interestingly, under the trend of electrification, the i4 M50 simulates engine sounds with electric motors, and a hybrid M5 might be launched next year. For track play, the M2 is recommended due to its shorter wheelbase for better control.

Collecting cars for seventeen years, I've learned the nuances of M series classification. The E36 M3 was the benchmark of the nineties, while the current G-generation models share a unified chassis suffix. Focus on the powertrain: the M2 uses the S58 inline-six, the M3 Touring shares the same engine with different tuning, and the M5/XM have switched to a V8 architecture. Personally, I believe the F87 M2 Competition will appreciate in value, as it's the last pure gasoline-powered rear-drive hot hatch. The new G80's hood bulge is too high and affects visibility, but its carbon fiber driveshaft is a real treat. For beginners, I recommend finding a used F30 340i and flashing the M Performance software for a high cost-performance ratio.

Worked as a docent at the Museum in Munich. Motorsport is essentially about trickling down racing technology to production cars. All currently available M models are based on the CLAR platform. To identify purebred M cars, check the naming convention: only those with independent chassis codes (e.g., M3 coded as G80) are true-blooded. The M3 Touring is the most recommended—its trunk can fit four slicks for direct track use. Note that Competition versions come standard with AWD, offering 30% better wet traction than RWD models. Northern users should opt for the M Carbon Ceramic Brakes for reduced winter performance degradation.
