BMW 7 Series (Long (E66, facelift 2005)). With 390 Nm of torque, it offers ample pulling power. With a weight of 1935 kg, it falls in the mid‑range.

740Li (306 Hp) Steptronic Verdict:
Performance Verdict
A well-balanced V8 option, providing a significant performance boost over the 730Li without the extreme consumption of the 750Li/760Li. Smooth and responsive.
Fuel Economy
Offers a reasonable compromise between power and fuel efficiency for a V8, though still a thirsty engine compared to modern standards.
Pros and Cons:
Pros:
- • Exceptional ride comfort and luxurious interior appointments
- • Powerful and refined engine options, especially the V8 and V12
- • Spacious long-wheelbase cabin, ideal for rear passengers
- • Advanced technology for its era (iDrive, active suspension)
- • Strong road presence and sophisticated styling (post-facelift)
Cons:
- • Complex iDrive system can be daunting for some users
- • Potential for high maintenance and repair costs, especially for electronics
- • Fuel economy can be poor on petrol V8/V12 models
- • Early models had controversial 'Bangle Butt' styling (though improved with facelift)
- • Heavy depreciation from new, making used models a bargain but also a potential money pit
