With the windows down, on a hot day, one disappointment is that instead of any audible evidence of the V6 engine (never as exciting as the V8, of course), there is instead that pervasive, ubiquitous electronic ‘hum’, now built routinely into electric-assisted cars, as a warning to other road users. It might well be necessary, but is also rather irritating inside the car, when you’re in electric mode. The other electric downside on a Hybrid that can also be plugged in is the need for cables, which take up valuable space in the boot, and even underneath it. You can’t win’em all.
