Red Bull RB7 Renault

A place to discuss the characteristics of the cars in Formula One, both current as well as historical. Laptimes, driver worshipping and team chatter do not belong here.

Certain architects claim credit for designing bridges and making columns slender on tall buildings. Bridge & tall building design is all about the mathematics of optimising weight for strength to achieve the span or height.

At least car designers are usually credited for "styled by" and don't claim to have designed the mechanics and handling.

So Mr Newey has been working on the idea for at least 4 years, hard to catch up what he must have learned.

I don't see what your saying with this picture...?

If your saying one side is lower, you can see by the tyres the car is leaning

To say that an F1 engine that has more torque is better for accelerating is ignoring a lot of things.

Snipped from an article: *The transmission amplifies or multiplies the torque coming from the engine by a factor equal to the gear ratio. So to determine how much the car is accelerating at a particular instant, you have to know both the torque output of the engine as well as the gear ratio.*

As the transmission gear gets higher (the ratio gets lower) it is much more important for the engine to have horsepower, since that power is now transmitted much more efficiently to the wheels (vs. the torque the engine makes). Basically, at a high enough speed, horsepower is what will keep your car accelerating.

With the huge Cd that F1 cars have to overcome, peak power is even more important for both top speed and for acceleration in med-fast corners.

You can't say that an engine in car A with more power will ONLY use that power to push it's top speed x% more than car B. It will in every fast corner be using more force to accelerate.


Of course this is ignoring a ton of OTHER variables such as powerband shape, peak rpm, fuel consumption, etc.

I'm just saying... it's dumb to say "Renault engine has more torque, therefore the Red Bull has better acceleration."
Since Power = Torque * RPM at a given speed the car with more power is also the car with more torque.
Basically, at a high enough speed, horsepower is what will keep your car accelerating
I can equally say the same by substituting torque since the two are directly connected.

No one is saying that.
It's about having flatter torque vs RPM curve.
That gives confidence to driver and better acceleration.

And I don't why 1994/1995 is given as an example. Too many variables, nothing like current situation.

Either you move up the ladder (politics), are happy working for your boss, or you jump ship to another company to advance your carreer. Newey did the same thing. Besides, SOMEONE needs to be the 'face' of the design team and take responsibility for both the success and the failure.

Bottom line: For what we get paid to do... don't feel bad that we don't get credit for everything we've done. Those who need to know, know. :wink:
Yes, it's not like any prospective employer wouldn't be aware of how the industry works. So if you were part of the design team, headed by Adrian Newey, who designed the RB6, then that would still carry plenty of weight.

Turned down the chance to meet Vettel at Silverstone in 2007. He was a test driver at the time and I didn't think it was worth queuing!! 🤦🏻‍♂️

AUTOSPORT.com features editor @TeamAnglais says:

"It is true that everywhere we try read between the lines, the Red Bull seems to be the fastest car. It's consistency over long stints and ability to make tyres last longer than we expect stands out. It's exit speed out of fast corners at Jerez was quicker than all the others, even when it was lapping slower. And the rear wing flap was opening earlier and for longer than all the others, suggesting a comparative surplus of downforce. But because of the nature of testing, that's all still guess work for us.

"The team isn't sandbagging, as such. As veteran F1 engineer Frank Dernie explained to us when he got in touch with Live at Jerez, it's far less vital for a team to spend time testing on qualifying fuel. So Red Bull is likely just focused on heavy fuel race pace, rather than trying to hide its performance from the likes of Ferrari and McLaren.

"We won't know for sure how quick the RB7 is until the first race, but you can be sure that the rival teams know more about each others' performance than we do."

I've been trying to figure out what the "growhouse" thing they are planting on the RW this year might be in aid of.

Do you guys reckon it's actually hiding anything (it is transparent!), or is it smoke and mirrors to distract you from the interesting stuff elsewhere?

I remember all last season, RedBull had a gang of blokes surrounding the back of the car whenever they could on the grid, but I don't think anyone ever worked out exactly what it was they were hiding.

I'm sure they had it last year too. Its just a shelf for tools and per regulations it has to be transparent so that they aren't covering up a part of the car.

I disagree.

They promptly whack that thing on whenever the car arrives in the pits, and it seems only to have horizontal members running from left to right, so placing even a small spanner on it as a shelf would cause it to sag.

I'd say that is definitely designed to cover something up from prying eyes, or a tactic to draw the eye of the oserver to it.

Has anyone got any juicy pictures of the rear of the RB7?

Judging by testing time sheets, the RB7 appears to be the most consistent car over long stints has it's the car that has less performance drop in the time sheets. My guess, it's there any possibility the longer wheelbase giving them that edge over tyre management?

Steve Matchett on SpeedTV mentioned this; Toyota was doing it as well. As was said, it's against the regs to cover the car, so the team(s) use clear plastic so it's technically not covered. But as is obvious, it's hard to see what's going on back there! I would love to see all the details in the rear, but on the other hand it's also neat to see how seemingly every rule has a loophole. :-)
