Can an EV Really Replace Your Petrol Car? We Put It to the Test

wo cars driving down a road next to each other, highlighting the question of whether an EV can replace a petrol car in the UK

Once upon a time, EVs were glorified milk floats. In 2025, they’re sleek, smart, and everywhere. But can they truly replace your petrol car? We grabbed a Kia EV6 and a BMW 3 Series, hit the road, and found out.

The Range Showdown

🛣️ The Test: London → Lake District (270 miles)

Kia EV6: 328-mile WLTP range; real-world = 280 miles with Spotify, heated seats, and “enthusiastic” driving.

BMW 320i: 470-mile tank; real-world = 430 miles (thanks to M6 traffic jams).

Verdict: The EV6 needed one rapid charge en route (~20 mins). Not bad for a car that runs on electrons.

The Cost Battle

💷 Kia EV6: Home charge (off-peak): £16. Rapid top-up en route: £11. Total = £27.

BMW 320i: Petrol at £1.65/litre: £69 for a full tank. Used ~60%. Total = £41.

Verdict: EV wins for home charging but loses at pricey rapid chargers.

Refuelling Time

⏱️ Kia EV6: 20-minute coffee break at Gridserve Braintree.

BMW 320i: 5-minute splash-and-dash at motorway services.

Verdict: Petrol is quicker. But would you rather queue for Costa or sniff diesel fumes?

Driving Feel

Kia EV6: Silent, instant torque, surprisingly agile. Makes stop-start traffic less painful.

BMW 320i: Classic petrol roar, linear power delivery. Great on the M roads, less fun in city crawl.

Convenience Factor

  • EV drivers need planning for long trips. Apps like ONEEV are essential.
  • Home charging wins. Imagine never visiting a petrol station again.
  • Petrol still edges it for spontaneous 500-mile cross-country blasts.

Future Proofing

⚡ EVs get smarter every month thanks to OTA updates, cheaper tariffs, and growing rapid networks.

⛽ Petrol? Same old. Plus ULEZ zones and fuel price volatility.

The Final Verdict

✅ For daily commuting, school runs, and 90% of life? EVs smash it. ❌ For unplanned, ultra-long journeys without charging prep? Petrol still has a slight edge… for now.
