The V6 is excellent. Lighter and better balanced car than the V8 - Mike Cross (JLR Chief Engineer) reckons it’s the one to have. The L405 is much lighter than the previous model so V6 is fine (it's much quicker than my old V8). I think they have sold lots more V8s, because if it’s your only car you tend to err on the side of more power, and people assume more means better, and RR is associated with V8 (nothing wrong with that!). Here’s the Pistonheads review at the launch: “The one to have, though, is the V6, preferably on the smallest, 20-inch wheels. 7.4 seconds to 62mph, 130mph, 196g/km, 442lb ft of torque and a £71,295 starting price. On real roads it might not have quite the ballistic surge of the V8s but it's plenty quick enough for an SUV. It, too, is ultra-refined and un-diesel-like, and it also both handles and rides the best. The V8s still feel a bit SUV-like, with large masses being shifted and a feeling of forces being fought, and they can thud heavily into road-breaks. The V6 steers sweetly and naturally, you're hardly aware of the minimal extra roll, and it eases beautifully over bumps while feeling much more agile than it should. Physics are defied best here.”
