What does 730 mean in cars?

[DominicLee]

In the automotive context, 730 refers to the BMW 730 and Baojun 730 models. Powertrain of BMW 730: The BMW 730 is a premium luxury sedan produced by German automaker BMW. As part of the BMW 7 Series, it is exclusively manufactured in Germany. The new BMW 730Li is equipped with a B48-coded 2.0T turbocharged engine delivering maximum power of 190kW (258PS) between 5000-6500rpm and peak torque of 400Nm from 1550-4400rpm, paired with ZF's 8-speed automatic transmission. In Sport mode, the transmission automatically downshifts to maintain engine speed above 2000rpm while the seats extend to provide enhanced lateral support. Powertrain of Baojun 730: The Baojun 730 is a 7-seat family vehicle customized by SAIC-GM-Wuling for Chinese households, developed based on extensive market research. The CVT version features a 1.5T turbocharged engine coupled with an 8-speed simulated CVT transmission. This engine produces 111kW rated power and 250N.m maximum net torque, with turbo engagement starting at approximately 1000rpm and achieving torque equivalent to mainstream 2.4L naturally aspirated engines by 1600rpm.

As someone who is particularly fascinated by cars, I often discuss BMW's model naming conventions. The designation 730 in the automotive world typically refers to a specific model within the BMW 7 Series, particularly the 730Li. Here, the number 7 represents BMW's flagship luxury sedan series, which comprises large, high-end vehicles. The following 30 denotes the powertrain variant. Unlike in the past, where it signified a 3.0-liter V8 engine, the current 730 model features a turbocharged four-cylinder engine, prioritizing fuel efficiency and emission standards. BMW employs this naming system to allow buyers to quickly identify a model's positioning. The 730, as the entry-level variant, offers a relatively affordable price without compromising performance—for instance, it delivers smooth urban driving. I recall that the BMW 7 Series has been around since the 1970s, with the 730 consistently being a staple in the luxury car market. If you're considering purchasing a car, understanding this nomenclature can help you compare different models, such as the 740 or 740Li.

I learned from a friend that the number 730 is primarily associated with BMW's luxury cars in the automotive world, especially the entry-level model of their 7 Series. Simply put, the 7 represents the large-sized luxury series, similar to BMW's flagship vehicles; the 30 isn't a specific displacement but a code for the powertrain, which nowadays mostly refers to efficient four-cylinder engines that are quiet and fuel-efficient. When I was researching before buying a car, I found that the 730 is quite popular in the market because it's significantly cheaper than the 740 in the same series, yet it doesn't compromise on space or comfort, making it practical for both daily commutes and long trips. Don't confuse it with other brands—for example, Rolls-Royce also has similar numbering, but 730 is almost an exclusive label for BMW. The number game is actually a clever trick by automakers to simplify identification.

In car models, 730 generally refers to models like the BMW 730Li, where the number code 7 indicates the series level, and 30 represents a specific configuration version. BMW's naming convention is quite intuitive—for example, the 730 is the entry-level option in the 7 Series, not the top performance variant, but it now features an upgraded engine with balanced power output and high fuel efficiency. I've driven it a few times and think it's suitable for those who seek luxury but have a limited budget.

I gained driving experience from a young age and remember that 730 is the standard model designation for the BMW 7 Series in automotive terminology. The number 7 represents the large luxury car series, while 30 used to indicate a 3.0-liter displacement, though engines have become smaller yet more technologically advanced today. BMW uses this numbering system to quickly convey information and avoid confusion; similarly, 740 denotes a more powerful version. In practical driving, the 730 is positioned as an entry-level luxury model, priced lower than higher-tier variants, making it suitable for family use or business occasions, with maintenance costs being less extravagant. The newly introduced hybrid version demonstrates the automotive industry's trend toward environmental sustainability.
