Ams2 and Real Cars [Just for Fun]

I searched for a long time but never found a right confirmation.
What kind of street car / which company is the base of the sprint cars?
Is it LEXUS CT?

 

It is not a LEXUS CT, it is supposedly a derivation of the Renault Superclio (at the beginning) then it became a totally independent product, manufactured with new parts and a new configuration that recalls the shape of the clio and with the Renault engine.
Our Brazilian friends on the thread know more.

 

I am sure it evolved from this, but it clearly has a Toyota/Lexus family "face" in its 2019 skin. But it's only a skin anyway, so not really important other than to know that some sponsor was interested in branding it a bit. The car has about as much to do with a Clio or a Lexus as the 2020 Corolla Stock Car has to a 2020 Corolla...which is to say almost zero other than the skin.

 

This popped up on my Youtube feed, I think it fits nicely here

What is the performance of the Ultima RS?

The Ultima RS has the overall performance parameter capability to surpass all world beating track times and performance statistics set by the previous generation Ultima cars.
Acceleration of 0-60mph in 2.3secs with a top speed capability of over 250mph being possible with the appropriate new LT5 drivetrain power output choice.

How are the aerodynamics improved on the Ultima RS model?

The design brief for the Ultima RS aerodynamics was to improve high speed stability whilst reducing the co-efficient of drag to achieve a more aerodynamically efficient car, resulting in market leading levels of downforce. Minimum co-efficient of drag achieved in the MIRA wind tunnel was 0.304 with the ability to adjust downforce to a maximum of over 1000kgs.

In brief:

The front splitter has been engineered to mount directly to the chassis, thereby removing any flexibility and putting loads direct into the chassis. The optional carbon fibre version also incorporates diffuser ramps to the underside to increase downforce while minimising the co-efficient of drag. The integral vortex generators on the outside points help to control wake around turbulent air from the front wheels, at the same time giving smooth flow to the underside of front dive planes (if fitted). The carbon fibre front dive planes can be used to move the aero centre of pressure further forward and produce more downforce on the front axle. The only downside with using dive planes is that they will increase the co-efficient of drag.
The re-design of the front body has reduced the frontal area to a minimum and also adds a lower co-efficient of drag. At the same time it controls air flow over the leading edge and maintains a boundary layer over most surfaces. Now that the radiator has a totally uninterrupted flow of air it has improved cooling efficiency.
We designed an integral S Duct system for the front canopy. To control airflow at high velocity the entry into the radiator will generate a stagnation zone between high pressure and low pressure; this backs up in front of the radiator as speed increases and will bleed off through new slots in the front body stiffener moulding and exit on the top surface of the front body. This also helps with an additional small amount of downforce on the front axle while maintaining low co-efficient of drag. If air passes too fast through the radiator core you generate a boundary layer so the heat from the radiator cannot attach itself to air passing through.
The RS carbon fibre side splitters work in a similar way to the RS front splitter in that they separate airflow most importantly when the car is in yaw with medium and high speed cornering, this in turn will increase downforce on loaded tyres and prevent air rolling underneath the side pod and creating lift.
Front and rear wheel arch vents (available in body coloured gel coat or an exposed carbon fibre finish) generate downforce and reduce drag. Rear vents have the added bonus of allowing hot air to exit from the exhaust headers. The new RS carbon fibre side pod scoops come with integral NACA ducts and provide air flow for the air conditioning condenser and to the new LT engine air intake system.
The RS radiator exit divider is used to initiate air separation around the wiper arm and then further up the windscreen. The wake is used to divert the boundary layer either side of the roof scoop intake. This minimises hot air from the radiator entering the roof intake.
In full size wind tunnel testing we recorded an identical co-efficient of drag with side pod apertures completely blanked off versus side pod scoops fitted. This is due to having a very efficient exit point in the new RS rear wheel arch louvre vents. This resulted in additional down force and the centre of pressure to the rear axle increased.
New optional RS carbon fibre rear view mirrors have been moved to the front bulkhead area on the centre section to minimise disruption of the boundary layer over the top surfaces and improve airflow onto the rear wing.
To improve the efficiency of the RS rear wing it is now larger and the full width of the body. It is mounted on a new bespoke swan neck mounting system which transfers downforce directly to the chassis. The new swan neck mounting system has been engineered to increase downforce and reduce coefficient of drag, minimising wake to the bottom surface of the rear wing.
The addition of a new roof scoop has been used to improve air flow over the top of the car and maintain a boundary layer over the top surface. It also uses the intake air flow to assist in engine bay cooling.
The RS carbon fibre rear diffuser is a design feature added to enhance the appearance of the car whilst improving air separation off the rear canopy.

What are the engine fitment options for the new Ultima RS?

The engine options are the LS range of Chevrolet V8 engines (LS3/LS7/LSA) and also the latest generation Euro 6 compliant LT range of direct fuel injection Chevrolet V8 engines (LT1/LT4/LT5). The fantastic new LT range of dry sump, emission friendly and supremely powerful Ultima engine options further increases the number of countries we can export the Ultima RS into. We have developed an all new Ultima plug and play factory LT engine installation package specifically for the Ultima RS model to comply with the latest worldwide regulations.
Even with a base LS3 crate engine at 430bhp, the lightweight mid-engine Ultima RS can propel itself to 0-60mph in 3.3 secs and over 180mph. More than enough for some serious fun!
We will not sell the Ultima RS supercar to any individuals who seek to install a different type of engine, to protect and safeguard our brand identity, purity and engineering excellence of our marque. The Ultima RS is comprehensively designed and engineered around the Chevrolet LS and LT engine installation, with a no compromise approach.

Where do I buy the engine from?

To coincide with the new Ultima RS public release we now sell all of the Ultima engine packages directly from ourselves at Ultima Sports Ltd and can quote for full engine packages for all of our clients. We no longer use American Speed in the USA as our recommended engine supplier now that the new LT GM crate motors possess this magnitude of immense and reliable power output as standard. Our standard LT5 crate engine fitment makes over 800bhp in our Ultima application!
The engine is one of the last items that a client needs to purchase and install once the rest of your Ultima RS build is largely finished.

Sprint Race in Interlagos:

 

That's the same with WTCC and DTM, it's only the shape which correspondense to a manufacture's serial car. Under the hood, everything is the same between the manufactures what makes it so boring these days. In eralier years, especially in WTCC, it was interessting with the difference of FWD and RWD cars, BMW h-shifter against Seat TDI or BMW - AlfaRomeo,.... Or Mercedes against Audi quattro in DTM...
Ok, but now I know which shape the SprintCars have, thanks.

 

In the case of the sprint car, the skin concept is even more exaggerated. The car is mid engined and the driver sits in the middle. Even further removed from the production car.

 

just because Im waiting for a takeaway! and need to get back on this track. Just the mention of his name brings back memories, he had an incident or 2!

What supprised me here is the gears he was in, during turns

 

Are the white circles on the inside of some of the major curves stones or just painted circles in 1987? Anyone know the details of whether/when they converted them to painted circles as we have in AMS 2? I know they were stones in real life at some point when this track layout was being used because you can see them clearly in many other videos.

 

Check if there is any images in this video, this guy was doing a review of the old circuit.

Reality check: Default Setup.Ginetta and Stock car 2020 stright line, 150kh, all brake in , without touch the wheel.
Uncontrollable and sharp left turn.
Normal?
In real life I would bleed the brake system.

It's the ladder on the roof that made the Uno faster

 

Yes, it's visually based on the old Copa Super Clio, but the Sprint Series is a completely different animal inside, keeping only the center seat position from the old series.

The New Sprint Race is a more aggressive car, with a more powerful engine and a less stable chassis. The idea was to keep up with the new Stock Car Brasil, that (despite the complains) is supposed to be a less friendly car than the previous version (yes... the AMS2 version seems to be spot on in the realism check).

 

Live now:

 

At last Saturdays Imperio Endurance Brasil Roco Racing Cars introduced the upgraded #82 Roco:

 

Roco 001 was named after the initials of Brazilian-based Argentine Robbi Pérez (who accelerated in the USA) and José Córdova from Paraná. And it doesn't hide its mechanical base: a Formula 3 Ralt RT34 chassis, with the wheels properly covered to meet the rules of the championship.

The engine, however, changes: it is a four-cylinder in-line 1,340cc that originally equips the Suzuki GSX1300R Hayabusa. As with every project start, the initial goal is to travel as far as possible, preferably smoothly, to fight for the first places in the category throughout the development.
