Driving experience

BMW Z4

This is where the E85 shines. Classic BMW rear-drive balance, a low centre of gravity and communicative (if slightly light) electric steering make it enjoyable on twisty roads. The chassis is agile and willing to rotate; it rewards smooth inputs and feels more involving than many later soft-tops. Ride is firm and can feel crashy over poor surfaces or with run-flat tyres — many owners improve it by switching to conventional tyres. The inline-six engines are the highlight: smooth, free-revving and characterful with a distinctive soundtrack. The 2.5i and 3.0i (especially manuals) are the sweet spots. The 3.0si is stronger and more modern-feeling. The 2.0i four-cylinder is less refined and less desirable. Open-top driving is the point of the car — wind noise is present but manageable with the windows up. Overall a genuine driver’s roadster rather than a grand tourer.

Volvo XC90

Composed and secure for a large SUV of its era, with light steering that suits motorway and urban driving. The ride is comfortable on standard wheels, and body roll is present but managed for the size. Diesels deliver strong low-end torque for motorway use. It prioritises comfort and safety over sharp dynamics, with good visibility.
