    • McLaren 600LT Magny-Cours GP circuit laptime test puts it ahead of the GT2 RS

      This is interesting because we already saw the McLaren 600LT finish behind the 991.2 GT2 RS and GT3 RS on the Magny-Cours Club layout. On the larger GP circuit, the 600LT outmuscles the 991.2 GT2 RS and 991.2 GT3 RS.


      However, the 600LT is on Pirelli Trofeo R tires. When the GT2 RS moves to Cup 2R tires it improves its laptime by over a second and easily outpaces the 600LT as well:


      Interestingly the 675LT is quicker on this track as well than the lighter 600LT.

      Maybe McLaren held back a bit?

        The 600LT will feature in the next Supertest of the German car magazine sport auto, out around the 10th of August.

        Drove a 570S two days ago which is already phenomenal performance wise, very impressive on the Nürburgring Nordschleife.

        You like it better than your R8?

        Both are great cars in their own right. And there are a lot of similarities like the mid-engined layout that provides such great traction and control, the excellent driving position and short front which makes them so easy to place on a circuit as opposed to front engined sports cars.

        They're also both phenomenally fast cars, and their potential on a track exceeds my driving skills. Throw them into corners, even coming in too hot and they just shrug it off.

        The difference is mainly in the drivetrain. Less so the transmission which is in both cases very fast DCTs, but obviously the engine. It dominates the R8 much more than it does the McLaren - the sound, the revs, the instant throttle response and the way it gets really going insanely fast beyond 6000 rpm. The McLaren’s is probably more powerful due to the torque of the two turbos, but the noise it makes industrial rather than thrilling and with not much happening below 3000 rpm, plus a sizeable turbo lag. On the track the latter doesn’t matter so much because you’re on the throttle and in high revs anyway, but you feel it in situations with on/off throttle inputs. That being said, for a turbo engine it loves to rev and, at least without a remap, its power delivery is quite linear and doesn’t run out of breath beyond 5000 rpm like so many forced induction engines.

        Another difference is the brakes which on the McLaren need to be worked much harder, after a normal street car they feel almost unservoed. Steering is also on the heavy side but so is the R8’s, which in both cases I like because it gives you lots of feedback and doesn’t have the Micky Mouse feeling of for example the new R8’s electro mechanical steering. It does mean though that in hairpin curves for example you need to work more to do the 180 turn, kinda old school.

        What you notice also is the significantly lower weight of the McLaren, in particular on the track when braking hard. The R8 hides its own weight well but you do notice the Macca has a few hundred kilos less to lug around. The carbon tub structure makes it incredibly stiff, you fell that when driving as if the whole car is made out of one single very solid piece. The R8 feels solid too, but in a chunkier way if that makes sense. At the same time the McLaren is surprisingly comfortable, soaking up bad roads very well and certainly better than my R8, although that comparison is slightly skewed as I opted not to have the MagneticRide dampers (as opposed to my first R8) but a passive suspension which is much firmer.

        Inside the McLaren is the far newer car, at least as far as the dials and speedo are concerned. But comparing it to a first generation R8 is probably somewhat unfair, and personally I like the analogue instruments of the older car. The Brit also consumes less fuel when you’re not pushing it, the V10 is a guzzler at any time - when stepping on it though they’re the same in terms of fuel consumption. McLaren also has a slightly bigger boot in the front, although that’s not really relevant for most people.

        In summary I like them both, the Audi mainly for its fantastic engine but also the consideration in the back of your head that it’s made by a giant car maker (reliability is a concern if you keep them longer or not under warranty when buying used) and garages are not few and far between. The McLaren is certainly faster, more sophisticated due to its carbon fibre tub and lighter on its feet - and of course more tuneable which for the readers of this forum is probably quite relevant too. When driving it on the track though you don’t think it needs more power, and personally I wonder if the fantastic balance between performance and traction wouldn’t become undone were you to remap it to another 100hp or more extra. Not that I wouldn’t want to try!

        Fantastic synopsis! Thank you.
