3 Answers
BMW 740i and 740Li differ in body dimensions: The 740i measures 5250mm in length, 1902mm in width, and 1498mm in height; the 740Li measures 5212mm in length, 1902mm in width, and 1478mm in height. The 740i is the standard wheelbase version, while the 740Li is the long wheelbase version. The BMW 740Li is a mid-range model in the BMW 7 Series, equipped with a 3.0-liter 6-cylinder turbocharged engine producing a maximum horsepower of 340 hp, a maximum power of 250 kW, and a maximum torque of 450 Nm. In terms of fuel consumption, according to the MIIT comprehensive fuel consumption data, the BMW 740Li has a combined fuel consumption of 7.5L.
The main difference between the BMW 740i and 740Li lies in the wheelbase length. Simply put, the Li is the long-wheelbase version, offering significantly more rear legroom. I've personally driven the 740Li, and with the extended wheelbase, the rear seats feel like a VIP lounge—you can stretch your legs fully, making it super comfortable for long trips with family or clients. Kids also have plenty of room to play without feeling cramped. The 740i, with its standard wheelbase, is more agile to drive, with a smaller turning radius, but the rear space is just average. It handles city driving well. Opting for the Li also gives you the optional rear-seat massage function. Both models share the same 3.0T six-cylinder engine, delivering identical power and similar fuel consumption around 10L/100km. The Li is pricier, but the extra space is worth it. Your choice depends on needs: if you love driving, go for the i; if it's for family or business, prioritize the Li—the extra space isn’t just about prestige, it’s genuinely practical. In terms of suspension, the Li is tuned for a softer ride, offering more stability at high speeds, ideal for long journeys. The i feels sportier, which might appeal to younger drivers. I recommend test-driving both at a dealership to experience the rear-seat difference firsthand.
As someone who has driven multiple BMW models, I believe the core differences between the 740i and 740Li lie in how their body dimensions affect driving. The 740Li has a longer wheelbase, and with its optimized rear suspension system, it offers finer vibration filtration and quieter performance over speed bumps. The 740i, with its shorter wheelbase, provides precise handling and more agile steering, making it more engaging when navigating city alleys or mountain road turns. In terms of space, the Li version offers ample rear legroom for passenger comfort, while the i is slightly more compact, better suited for solo driving or occasional passengers. Both share the same engine, achieving 0-100 km/h in 6 seconds, though the Li's slightly increased weight makes little noticeable difference in hard acceleration. Configuration may vary: in some markets, the Li comes with more rear-seat options like USB ports and heated seats. The Li is priced higher but offers added space utility. Choice depends on usage: the i is better for frequent city driving, while the Li excels in long-distance or passenger-heavy scenarios. Stylistically, the Li features smoother lines for a more imposing look, whereas the i is more understated and refined. Maintenance costs are similar, with wheelbase length not complicating repairs.
