Today's new Daily event is a Hot Lap at Silverstone GP in an Audi V8 quattro DTM. A little slow to be ideal for Silverstone, really. Don't let the understeer catch you out on some of those high-speed corners.
The new Weekly event is a Pace Setter at Nurburgring GP in a Porsche 919 Hybrid prototype. Definitely more of a challenge; this car is fast, especially when you punch the hybrid boost, and it gets more than a little tail-happy out of some of the turns here. It also turns very, very well, though (especially right after driving the quattro!); I drove off the inside of more than one corner on my first run because it changes directions so quickly even at high speeds that it caught me off guard. Once you get the feel for it, though, this thing *flies*! Just make sure you keep track of your lap count and dump all of your remaining boost right out of the last corner on the final lap so it doesn't go to waste. Otherwise, I think you get the most out of the boost in 5th-6th gear, where it really improves your acceleration and lets you reach ludicrous speed. You'll want to use some on a couple of the shorter straights as well, though, just to make sure you're getting the most out of it; no point in going into a braking zone with a full meter.
