The 30d is the ‘sweet spot’ in the X5 range. While it’s always nice to have the extra power offered by the 40d and thundering triturbo 50d, the 190kW/560Nm outputs of the 30d’s single turbo 3.0-litre six suffice quite nicely. The XC90 on trial is the most German of the model range, the R-Design, wearing its sport styling and black-on-black interior trim. Other than the yet-to-be released T8 hybrid, it’s the priciest too at $112,990 in T6 guise. It’s the one with the 236kW/400Nm 2.0-litre petrol four, its outputs boosted by a supercharger and then a turbo, although here it’s been given a further boost with ‘Polestar Optimisation’ adding a few kW and a few units of torque thanks to ECU fiddling.
