Unsupported EMG R-One concept 2020 2.0

‘’Light is right’’, Colin Chapman (engineer, inventor, and founder of Lotus cars)

Hello everyone, today, I’m going to show you my biggest project: a RWD track beast, the EMG R-One concept 2020.


Be prepared for a long presentation!

Chassis:
All in this car is designed to be as light as possible: massive use of carbon fiber, monocoque chassis, no power steering, low safety level, 1.9L mid-engine, optimized brake size … The result was just too light (705kg), so I have change the body panels´s material for a final weight of 950kg.

It’s recommended to use this car without ESP, even for keyboard users, if you want to use it at its full potential. The suspension and tire settings give to the car an awesome grip. This beast can handle a side acceleration of 1.4g at low speed, and almost 2g at high speed with its extreme aerodynamic configuration. If you try to take a corner too fast, this track toy will understeer and stay perfectly controllable, at low speed and at high speed. As a result of all this, the EMG R-One concept is quite easy to drive. But you have to know that the car tends to oversteer for better cornering abilities.


This car is designed to be RWD, but if you have trouble driving it, you can find an AWD transmission in the part selector

Engine:
You will find in this car probably one of the most glorious engines of all automation cars. Why? Well, because this tiny 1.9L inline 6 turbo engine produce 530hp. That’s right, this engine has an efficiency of 279hp/liter, my personal best score! But, to be honest, this engine has two downsides. First, the engine needs to be use between 4000rpm and 8000rpm. Under 4000rpm, it has almost no torque. The maximum power is reached at 8000rpm. The second downside of the engine is… the sound. The sound is really ugly. Because of that, this car use a custom sound.

If you think this car deserve more power, you can install a supercharger, pushing the engine until 677hp. If it still not enough, then you can use the fully customizable NO2 system!

Configurations:

• 2-Seq: stock engine, RWD 7-speed sequential gearbox, top speed: 270kph
• 2-DCT: stock engine, RWD 7-speed DCT, top speed: 270kph
• 2-M: stock engine, RWD 6-speed manual gearbox, top speed: 270kph
• 2-Seq SC: supercharged engine, RWD 7-speed sequential gearbox, top speed: 320kph
• 2-DCT SC: supercharged engine, RWD 7-speed DCT, top speed: 320kph
• 2-M SC: supercharged engine, RWD 6-speed manual gearbox, top speed: 320kph
• 4-DCT: stock engine, AWD 7-speed DCT, top speed: 270kph

Global specs (for the 2-seq configuration):


The history behind the car:
I have started this project in september 2019. I have made a huge number of prototypes, you can even try one of them, named EMG S599 2020, with my car pack. The first build was a front engine car, but the handling in corner was amazingly bad, this car was an understeering machine. I have tried to put the engine in another location. Because the mid position can only fit small engine, for the second build, I choose a rear engine configuration. The EMG S599 2020 is the last version of this build. The handling was just the exact opposite of the first build. This car is almost undriveable, because all the weight is on the rear, making this car oversteer as hell. For the third build, I have chosen a mid-engine configuration. The first prototype was running with a 1,2L inline 4 turbo engine, who produce 120hp. The result was pretty nice, the balance was way better than the two previous builds, even if it was far from perfect. Also, because of the lack of power, the car was boring to drive. First, I have tried to do the biggest engine possible in this configuration: 1.9L inline 6 turbo engine. When I was satisfied with the engine, I have started working on the chassis, to get the final result that you can try out now!

One last thing, the ‘’39’’ on the side of the car is not here for nothing. I have 39 different version of the R-One concept, each one come with a complete rework of something of the previous version, not just small adjustments or esthetical modifications. The S599 2020 that you can find in my car pack is the version 23.

More than ever, any advice would be appreciated
