In a world where compact and efficient V6 engines have taken over, there's still something undeniably special about the straight-six. Known for its smoothness and balance, this engine design has seen a resurgence in recent years, gracing vehicles from prestigious brands like Mercedes, JLR, Stellantis, and Mazda. However, for those on a budget, acquiring the experience of a straight-six doesn't require breaking the bank. This article explores six affordable cars that deliver the buttery-smooth performance of a straight-six engine for under £10,000.

A Journey Through Affordable Straight-Six Vehicles

Among the many models available, BMW stands out as a steadfast supporter of the straight-six layout. The BMW 135i, launched in 2007, features a turbocharged N54 engine with an impressive 302 horsepower, making it a hidden gem for enthusiasts. Meanwhile, Lexus offers the IS series, blending sportiness with rear-wheel drive, powered by either a 3.0-litre or a smaller 2.0-litre straight-six engine. For those seeking Scandinavian elegance, the Volvo S60 and V60 T6 provide a modern take with all-wheel drive and up to 325 horsepower after optional upgrades.

Further back in automotive history, the Jaguar XJS presents a stylish option with either a V12 or a more manageable 4.0-litre straight-six. On the other hand, if reliability is key, the Jeep Cherokee (XJ) might be the perfect choice, equipped with a robust 4.0-litre straight-six known for enduring extensive mileage without issues. Lastly, the Mercedes SL320 (R129) combines classic appeal with a powerful 3.2-litre M104 engine, offering both style and affordability.

Each of these vehicles represents a distinct era and approach to automotive engineering, yet they all share the common thread of the straight-six engine's unparalleled smoothness and balance.

From a journalist's perspective, exploring these options reveals the enduring appeal of the straight-six engine. In an age dominated by technology and efficiency, these vehicles remind us of the importance of preserving automotive heritage. They demonstrate that sometimes, the best innovations are not always the newest ones. For car enthusiasts and casual drivers alike, experiencing the silky smooth power of a straight-six can be a transformative journey into the heart of what makes driving enjoyable.
