So then, the new Volkswagen Passat eHybrid is a really good plug-in hybrid. It will do 73 miles on electric power at 3.6mpkWh, then carry on using its petrol engine while still doing over 50mpg a lot of the time, and it’s pretty hard to argue with that, right? Allow me…

I’m not about to dispute any of the findings of that test – because I wrote it – but in my view, the concept of a PHEV is fundamentally flawed. That new VW system is pretty remarkable and makes the Passat a very competitive PHEV. But even this one just seems like the worst of the electric and pure-ICE worlds. 

Some people choose a PHEV as a company car to get the low BIK tax even though they can’t slow charge it while doing something else (like sleeping or working).

If that’s you, I don’t blame you, because that’s how our tax system operates at the moment (although it will become much less favourable to PHEVs from 2028).

But at that point, it’s a loophole rather than the right solution. After all, the mild-hybrid version of that Passat is several thousands cheaper, gets about the same fuel economy and is overall slightly more natural to drive.

The Passat can use DC rapid chargers, but those are so expensive that you would be better off just running it on petrol.

If you do have the ability to charge it regularly, then why not get a proper electric car? You’re going to be running the hybrid on the battery and electric motor most of the time anyway, while carting around a redundant engine.

In the case of the Passat, that means you have 108bhp at your disposal – adequate, but not exactly a near-£50,000 experience. Meanwhile, the Passat’s electric counterpart, the ID 7 Tourer, has more than double, at 282bhp.

I’m as partial as anyone to a flat six and a manual gearbox, but I’ve no love lost for a thrashy four-cylinder with an automatic – that’s just a means to an end.

With more power that’s smooth and silent to boot, as well as a more entertaining rear-drive chassis, the ID 7 is a better driving experience all round.

Ah, “but the range and the charging infrastructure”, you say. In our road test, we found the ID 7 will do a real 277 miles on the motorway, after which it will charge back up to 80% in less than half an hour.
