Assen MotoGP, London Formula E and more

Moto3 - Assen: Quartararo takes the lead from Oliveira, then fends off his repassing attempt.

Kent is trying to pass Fenati for fourth.

Moto3 - Assen: Oliveira slides inside Navarro into the lead at the flat-out kink at the back of the circuit, then resists both Navarro and Quartararo into the first corner as they begin the last lap.

Formula E - Battersea: FP2 has been delayed because all the drivers have been summoned to race control. Those track revisions are presumably the subject of the discussions.

Moto3 - Assen: We're approaching the final two laps with Navarro now into the lead ahead of Oliveira, Kent, Quartararo and Bastianini, then Fenati and Binder clinging on.

BTCC - Croft: AUTOSPORT's vantage point for that session was at the outside of the run between the Jim Clark Esses and Barcroft, where the cars look wonderfully on the limit.

One driver who had a couple of 'wide moments' was BTCC debutant Nicolas Hamilton. The AmD Tuning Audi S3 driver - who also happens to be the younger brother of Formula 1 world champion Lewis, in case you've heard of him - was 26th in his first official session in the championship.

DTM - Norisring: After a warm Friday at the Norisring, Saturday is wet. A steady wet that looks set to hang around all day.

Defending winner Robert Wickens topped practice for Mercedes, ahead of Mike Rockenfeller, Timo Glock, Timo Scheider and Jamie Green. The championship leader led the way for the bulk of the session.

We'll bring you qualifying from 12:25 BST and the race from 3:45pm BST on AUTOSPORT Race Centre Live.

Robert Wickens fastest for Mercedes in wet practice

BTCC - Croft: First practice has finished in the north east, and sophomore racer Tom Ingram ended up quickest.

The Speedworks Toyota youngster set a 1m24.567s to top a session that yielded little in the way of genuine laptimes - though Ingram's best was only a fraction slower than Colin Turkington's FP1 benchmark from 2014.

Andy Priaulx and Martin Depper were second and third, while Jason Plato logged just eight laps and wound up 15th with a power steering problem.

WTCC - Paul Ricard: Over at the Circuit Paul Ricard, the WTCC field is taking to the track for the second practice session.

Earlier this morning, it was Yvan Muller, at his home circuit, topping Jose Maria Lopez in the timesheets.

Moto3 - Assen: It's getting ever more fraught in the lead battle, though it's helping Oliveira and Fenati get away a little in first and second as the wilder stuff happens behind.

Quartararo just squeezed into the tiniest gap in the pack into the chicane and somehow kept himself and all his rivals upright.

Moto3 - Assen: Valentino Rossi's protege Romano Fenati has joined the lead battle, and briefly got himself in first.

Typically Fenati has done so from eighth on the grid. The young Italian is super-fast but prone to qualifying badly (eighth isn't at all bad by his standards) or going missing in races occasionally.

Malaysia's big hope Fahmi Khairuddin tangled with Remy 'son of Wayne' Gardner at the chicane just now. Looked like a sore landing but Khairuddin appears to have escaped serious harm.

Fenati, Bastianini, Oliveira, Navarro, Kent, Quartararo, Binder is the race order with 14 laps left.

Moto3 - Assen: The early running is being made by four of the men on the season - emerging stars Bastianini, Fabio Quartararo and Miguel Oliveira, plus runaway points leader Kent.

While Oliveira is now blossoming having been around a while, Bastianini is only in his second year and Quartararo is a rookie sensation who had the rules bent in his favour to get him on the grid before he was 16 - such was the organisers' excitement over his performances in the ferociously competitive Spanish series.

Moto3 - Assen: Our motorcycle racing day is kicking off in a moment with Moto3, where Enea Bastianini ('The Beast') has pole for a second straight race.

The man who looks ever more like Britain's next motorcycle racing world champion - Danny Kent - starts fourth behind Jorge Navarro and Karel Hanika.

As usual with Moto3, we'll keep our updates sporadic until things settle down. This is a pretty good layout for the little bikes (where isn't?) so our bet is a lead train of 10-15 bikes for the first half at least.

Good morning and welcome to AUTOSPORT Race Centre Live.

A few times every season we get a weekend when Formula 1 is taking a break and pretty much the entire rest of the motorsport world happens all at once in its place. And frankly we love that.

So stick with us over the next two days to keep in touch with everything going on in...

* Formula E's championship decider in London

* MotoGP's famous Dutch TT (and Moto3 and Moto2)

* A touring car bonanza: the DTM at the Norisring, World Touring Car Championship at Paul Ricard and British Touring Car Championship at Croft

* The in-the-spotlight Formula 3 European Championship at the Norisring

* United SportsCar's six-hour race at Watkins Glen

* The European Rally Championship's Ypres classic

* The NASCAR Sprint Cup in road course action at Sonoma

And quite possibly some other stuff we've forgotten.
