We've got a team of journalists and a photographer in the LA Convention Centre, seeking out all of the best news, interviews, opinions and photographs - and you can find the very best of what they have to offer in our live blog below.
16:38 Time to ramp up the debate: what do you think of the VW Beetle Dune. It has divided office opinion, with the vast majority recoiling in slight horror, but a small minority being rather charmed by its exaggerated looks. Better to be loved by 10% of people than cause no reaction at all among 100% of them? As ever, let us know what you think in the comments section below.
16:32 Off the freeway and in to the show halls, John McIlroy has headed straight to the Fiat stand, hoping to get an early peek at the 124 Spider in the metal. Seems Fiat saw him coming, however... he's been told he needs to wait a couple of hours yet.
16:25 Mind you, perhaps we should all hope the Prius sells well, to offset the emissions on another car that is likely to make its presence felt in and around the famous Hollywood hills. We drove the Bentley Bentayga and liked what we found - and expectations are that customers will be lining up on the LA Auto Show stand to put down deposits this week.
16:21 As the crowded freeways take a toll on our team, we start to understand why today was the day that the first driving impressions of the new Toyota Prius went public, as well as the spectacular mooted emissions figure of 70g/km of CO2. California in particular drives green car development, through its mixture of stringent laws and eco-conscious buyers. The verdict from editor Matt Burt (who drove the car in Japan, but wasn't allowed to say so until today) is that they will like what they find.
16:17 Still, the announcement of a new, rear-drive Lambo shouldn't be sniffed at. The full story on the Lamborghini Huracan LP850-2 is here, and to whet your appetite here's a picture:
16:14: Winkelmann's revelation to John that there's no scope for a manual has set our man thinking overnight, and he's written a blog on what the decision means for the Huracan in particular and Lamborghini's future models in general. Let us know your thoughts below - but it's news that is currently sticking in the craw of car enthusiasts around the internet, as they pick up on the story.
16:09 It's not all about the Fiat, however. There's plenty more of interest, and already digital editor John McIlroy has had a chat with Lamborghini CEO Stephan Winkelmann. It goes without saying the new rear-drive Lamborghini Huracan was the focus of their chat, but there are some (disappointing) revelations about the liklihood of a manual model making production too. The full details are here.
16:05 And while we wait for our team to negotiate the freeways of LA (yes, they are stuck in traffic...), we'll take a first chance to look back at the heritage of the Fiat 124 Spider. There's a fuller history of the car at the end of Hilton's blog, but here's a taster of what you'll find...
16:03 Already, our Hilton Holloway has been pondering the importance of the Fiat 124 Spider, offering up his theory as to why the car's launch is so important to Fiat, and most particularly why it is so important to Fiat's ambitions in the USA. Read his insights in this blog.
15:59 This year, we have several important launches, but none more so than the Fiat 124 Spider, which burst on to the internet in the early hours of this morning. We'll be getting a closer look at the car later today, but all we know so far is in this Fiat 124 Spider new round-up.
15:53 The show's relevance has long been through peaks and troughs. During the dark days of the recession, when the Detroit motor show was struggling along with its home car makers, it shone like an optimistic light for the American car scene. But in subsequent years its fortunes have varied according to level of support it has had from car makers (usually foreign ones) looking to make a splash. Variously BMW, Jaguar, Honda, Land Rover, Mazda and Mercedes have used it as a springboard to garner attention.
15:51 The first debate around the show is what to call it - Los Angeles motor show? Los Angeles auto show? LA one or the other? Does it really matter? Probably not, but for the pedants among us the people that run the event call it the Los Angeles Auto Show, or LA Auto Show for short.
15:49 The 2015 Los Angeles motor show doors are open, and Autocar is there to bring you the very latest news, pictures and analysis.
