Si4. What’s that mean? Well, it means that under this very big, very heavy Discovery’s substantial bonnet lives a tiny engine that, only a few years ago, no self-respecting carmaker would have dreamt of fitting to anything bigger than a Mondeo. It’s a turbocharged 2.0-litre, four-cylinder petrol with 300bhp and 295lb ft, giving 0-62mph in 7.7 seconds and 124mph. Which, for a car that weighs almost as much as the bricks and mortar of the factory in which it’s built, isn’t half bad. The V6 diesel Disco we’ve been running for the last few months is about half a second slower to 62mph, but makes up for the increased weight (+137kg) with an extra 148lb ft of THRUST. The price difference is a whopping £600 in favour of the petrol – less than the cost of speccing a towbar. Nice. That’ll go on petrol, surely… Now, ‘our’ TD6 isn’t the most economical car in the world. On a long, motorway run you might see 30mpg (JLR claim 39.2). That’s at a steady 70mph – up the speed a bit (where legal, obvs) to 80-85mph, and it tanks down to mid-twenties. Even from a big, heavy diesel SUV with the aerodynamic properties of a Georgian mansion, that’s quite rubbish. And the trip computer is hopelessly optimistic, promising a few mpg over what proper math claims the Disco is actually delivering.
