Sat 10:29 Moto2 - Assen: The race is going to be cut to 16 laps from 24 but won't happen till 12.47 local time, just over half an hour late.The MotoGP field really will be rushing onto the grid.
Sat 10:26 Moto2 - Assen: A replay suggests Salom ran into the back of Anthony West, which sent his bike tumbling end over end onto the run-off. It presumably spilt enough fluid on the way to alarm race direction.Salom had a bit of a limp as he got up but seemed more concerned that his bike was turning into a bonfire.
Sat 10:23 Moto2 - Assen: We've got a red flag. Salom's problem has covered Turn 1 in oil.It'll be a complete restart, perhaps a shortened race and a compacted gap before MotoGP.
Sat 10:22 Moto2 - Assen: Reigning champion Rabat grabs the lead off the line, ahead of a sliding Jonas Folger and Zarco.Lowes fell back to sixth, while Luis Salom (who really hasn't had the best time in this series) is on the ground with his Pons bike firmly on fire. Salom is OK.
Sat 10:20 Moto2 - Assen: Next up at Assen will be Moto2.Normally the pattern is: Moto3 brilliant, Moto2 dull, MotoGP pretty good and made brilliant by the calibre of characters even if the race isn't.
But the last Moto2 race at Barcelona was superb, with poleman Johann Zarco fighting back from a first-lap brush to take a last-gasp win.
Zarco's on pole again now, with Tito Rabat and Sam Lowes alongside.
Sat 10:20 European Rally Championship - Ypres A surprise element to this year's Rally Ypres is a trio of Porsches driven by very special drivers.Four-time WRC rally winner Francois Delecour, 2010 Le Mans winner Romain Dumas and 'forceful driving' legend and multiple Belgian rally champion Patrick Snijers all make take part in the R-GT category.
Delecour and Dumas were tied for ninth overnight, while Snijers had a spin earlier in the day and lies 27th. Expect Snijers to come through the field pretty quickly today.
Sat 10:19 Goodwood Festival of Speed: As well as following all the worldwide racing action on AUTOSPORT this weekend, you can watch the Goodwood Festival of Speed live:Right now our own HENRY HOPE-FROST is chatting to the nation's own MURRAY WALKER ahead of the classic racing motorcycles then the contemporary Formula 1 cars hitting the hill.
Sat 10:06 European Rally Championship - Ypres: Rallying is far from left out of this massive bumper motorsport weekend, as Rally Ypres is well under way.The prestigious Belgian event forms part of the European Rally Championship, with series leader and Peugeot 208 T16 factory driver Craig Breen leading overnight.
Interestingly Breen's ex-Peugeot team-mate Kevin Abbring led early on Friday, but rolled his Citroen out of the event.
Rally journeyman Bryan Bouffier lies second – also in a Citroen – after setting four fastest stage times yesterday making up for a slow puncture and close encounter with a ditch.
Last year's Junior champion Stephane Lefebvre made full use of his local knowledge, as he only lives down the road. The Frenchman is an impressive third considering it's his first time on the rally in an R5.
Sat 10:06 Formula E - Battersea: It's now single-file through Turn 1 under no-overatking yellows, with the TECPRO barriers effectively shrouding the rollercoaster bump that was causing all the problems.It hasn't stopped an improvement in the times. Buemi has just gone quickest with a 1m26.433s - a couple of hundredths quicker than Sarrazin's first-session best.
Sat 10:02 WTCC - Paul Ricard: It's Ma Qing Ha who finishes top of the session after a chaotic end.The final minute was filled with drivers running wide off the circuit and Lopez was one of them. A lap almost certain to improve his position of 11th went out the window and Hua stayed top.
Sat 09:58 WTCC - Paul Ricard: Into the final few minutes here and it's Ma Qing Hua on top, Lopez is down in 10th while Muller is back out on track. Loeb still in the pits with Tiago Monteiro.Time for late position changes?
Sat 09:56 Moto3 - Assen: Fabio Quartararo didn't enjoy being beaten by Miguel Oliveira in that one and was punching his thigh in frustration (the thigh - a body part Niki Ajo has yet to cross the finish line on).But he's cheered up by the time he joins an ecstatic Oliveira and the ever-present Kent on the podium.
Here's how they finished that one:
1 Miguel Oliveira2 Fabio Quartararo +0.066s3 Danny Kent +0.117s4 Jorge Navarro +0.179s5 Romano Fenati +0.252s6 Enea Bastianini +0.526s7 Brad Binder +0.540s
That was the lead group, then this lot...
8 Karel Hanika9 Niccolo Antonelli10 John McPhee11 Francesco Bagnaia12 Andrea Migno13 Livio Loi14 Hiroki Ono15 Philipp Oettl16 Jules Danilo
...finished covered by just 1.260s too as they fought over the final points.
Speaking of points, Kent marches on:
1 Kent 1652 Bastianini 1083 Oliveira 1024 Fenati 865 Efren Vazquez 766 Quartararo 74
Sat 09:49 Formula E – Battersea: FP2 will begin at 10:50 am local time and will run for just 25 minutes.
Sat 09:46 Moto3 - Assen: Wisdom (and a plug for an Aussie TV channel but it would be churlish for us to edit that out from his tweet) from a V8 Supercars (and Formula Ford) legend.Russell Ingall's verdict on Moto3: "That was one of the best races I've ever seen on @Fox_Motorsport The Moto3 riders bang fairings way harder than V8 drivers bang panels."
Sat 09:43 WTCC - Paul Ricard: We've had some surprising names at the top of the times but normality is resuming as Sebastien Loeb goes top.Yvan Muller quickly follows into second just 0.047s off Loeb's 1m30.845s effort.
Sat 09:42 Moto3 - Assen: Meanwhile... wow. Niklas Ajo was spat off the track at the chicane on the run to the finish, fell off the bike, somehow kept it upright as he clung to the handlebars and scooted down the grass on his knees.He remained like that all the way back onto the circuit and then crossed the finish line in the same pose.
Only 17th but physics defying brilliance there. Which we probably haven't described adequately.
Somewhere between circus and contemporary dance on a not-quite-crashing motorcycle, at very high speed, across grass and asphalt. That better?
Sat 09:38 Moto3 - Assen: Quartararo takes the lead from Oliveira, then fends off his repassing attempt.Kent is trying to pass Fenati for fourth.
Sat 09:36 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.
Sat 09:34 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.
Sat 09:34 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.
Sat 09:33 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.
Sat 09:28 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.
Sat 09:27 Moto3 - Assen: While our lead pack are being pretty sensible, the battle for the minor points places has been a violent one.We've just had Juanfran Guevara slide into Aspar Mahindra team-mate Francesco Bagnaia in a shunt in which Isaac Vinales ultimately came off worst, then next time around Vinales's Husqvarna Laglisse team-mate Maria Herrera's race ended in the gravel thanks to Niccolo Antonelli.
Sat 09:15 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.
Sat 09:12 MotoGP - Assen: Meanwhile it's been a very busy weekend for news in the top class already.Yesterday MotoGP chiefs agreed a package of rules designed to ensure a 24-bike field through to at least 2021, including a technical regs freeze, mandatory customer bike supplies and more financial assistance for teams.
Then came news of another change, as the Grand Prix Commission decided that Ducati would lose its concessions sooner than expected. No more extra development or soft tyres for the Italian bikes next year.
Meanwhile in the warm-up, Marc Marquez was fastest, Dani Pedrosa hurt some fingers and Alvaro Bautista hit a rabbit.
Sat 09:09 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.
Sat 09:00 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.
Sat 08:54 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.

* 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
