BMW i4 (G26)
The BMW i4 is one of the best-driving EVs on the market, brilliantly blending the classic handling of the 4 Series Gran Coupe with a smooth, silent electric powertrain. Positioned as a direct rival to the Tesla Model 3, it appeals to UK company car drivers seeking low tax rates without sacrificing premium build quality or driving dynamics. It is proving to be highly reliable, with excellent real-world range and charging speeds, though early cars can suffer from minor software glitches. It perfectly suits buyers wanting a traditional, sporty BMW driving experience that just happens to be electric.
