No. I came for the Bugatti, I saw no Bugatti. But why do I expect munkees would know what's a Renault/Lambo/McLaren from a Bugatti?

This achievement has earned you your "Pop Star" Level 71 Badge!

If you pause the video @9s in, you'll see a footnote, that says this car is only valid for the Indian market. It also says that this model is made in India (the law in India makes importing cars super-expensive, so any car maker that wants to sell there has to put a factory there). Renault has much higher EU safety regulations for the cars that it builds in France and Romania.
There are some cars sold in India (Tata Nano for example) where the seatbelts are even optional.
I think the reasoning is that it's marginally safer than transporting your family on a motorcycle, which is common.
Also, random cattle crossing the street have the right-of-way, even on highways.

For open wheel racing, Indycar is where it's at these days IMO. Since they changed to the DW-12 chassis, lost the stupid blocking rules and brought in some new talent and sponsors, the racing has been fantastic. Unfortunately, I don't care for oval racing, but it looks like its weighing even more towards road and street courses next year.

I wouldn't want F1 to become a spec series, but they need to do something to either make the racing closer or the technology development more interesting. The WEC has been the most interesting development series lately. It's guaranteed that Mercedes, Ferrari and Renault would never allow it, but opening up the engine regulations to allow more freedom could bring in other manufacturers itching to show off their hybrid technology as something sexy and powerful.

Inside the 2014 Renault F1 engine has been added as a related post - related requested by oritteropo.

Yes. The naturally aspirated v8 engines were increasingly irrelevant for road car technology, so the aims of the new engine rules were to introduce the types of technology that are relevant to road cars (turbo, regenerative braking, fuel efficiency).

Two less-intended side effects are that these are the most expensive engines ever (in an era when everybody is talking about cost reductions!) and that everyone is wondering whether anyone will finish the first race...

They actually had the battery packs last year, but this year have reduced the fuel allocation by a third but without reducing the power output of the power units.

Thanks And yes, it does. I saw it in my yt feed, but hadn't watched it yet.

Red Bull Racing are the reigning champions, but after the huge problems faced by all the Renault powered teams people are wondering if they will even finish the first race on Sunday! In fact people are wondering if anyone will finish, or if it will be a count back after the last car stops on track to allocate points!!!

Anyway, I don't normally watch a lot of tv, but this weekend plan to be glued to the set

First audio clip of Renault 2014 F1 engine has been added as a related post - related requested by oritteropo.

The V6 turbo is intended to develop technology that's more applicable to road cars, rather than the previous F1 approach of just spinning the engines faster and making the components thinner and lighter. They are also introducing much more restrictive fuel economy measures (via mandated maximum flow rate to the engine rather than the current limit of as much as you can carry at the start of the race). Also, as the video mentioned, the energy recovery system is going to be more integrated next season.

The new engines specs sound, superficially at least, similar to Indy car engines... I wonder if they will be close enough to allow any crossover?

The first clips of the new engines being fired up have already started to show up on yt:

The four mountain peaks on the corners of the fuel cell are where the lift pumps gather fuel and pump it into the central fuel collector... from there a high pressure pump feeds the engine.

The 40kg of fuel in this simulation represents about 25% of the full fuel load at the start of a race, 58 litres, compared to a full fuel tank which has 160kg/230L

Yes, exactly. It seems strange that they were seeing failures from springs at such low engine rpm's, but in any case I have heard that you just can't achieve more than 18,000rpm with springs no matter what.

I have found a web page with some nice diagrams and explanations of the electro hydraulic system used by Renault... they have indeed done away with the cam entirely (at least in testing, not sure if it has raced since that article was published). Since the engine management system would have to manage this, and it is a control unit supplied by McLaren, we can be fairly sure that all the engine manufacturers have a common system.

It seems like such a waste to be compressing those springs thousands of times a minute... or to be driving the rotation of heavy cams for that matter.
Someday this may all be electronic. Renault is playing with that aren't they?

In case anyone is wondering, modern F1 engines use springless pneumatic valvetrains, using Nitrogen instead of springs. It was only a few years after this video that F1 started using pneumatic actuators, I think it was the mid-80s Renaults.

Desmodromic valvetrains are sometimes used in motorbikes (Ducatti uses them for instance) but they would be too heavy for F1, and I don't even remember anyone experimenting with the idea.

Well this one is the weakest of the pit stop features, but I liked the first three and posted this on the back of liking the others more!

The teams are all so secretive that they would never make the interesting technical discussion that we want... if you take the Sauber cutaway series for example, gearboxes would be an obvious episode to cover, but for contractual reasons they can't show us the inside of their gearbox because it comes from another team! These videos are the best that I can find, but unfortunately most F1 fans will have seen them as filler pieces during the race coverage

I do feel that I have failed in tagging and channel assignment though, can you suggest what I should have put to avoid wasting your time? The more technical ones will always be in the engineering channel, and the less technical ones will be in sports/wheels.

I did post a few which were a little bit more interesting from a technical point of view:
