[UE4] Spec Series Racing Build Challenge


#118


Eagle 208 Base is pretty normal compact car with a sporty appearance (made possible thanks to @MartinPL’s visual design). It has just 116HP from a 2.0 I6 NA engine and an automatic gearbox, but is also practical and economical (6,2l/100km). A very good fun car for under $11k.


Eagle 208 Track is where some the fun comes in - the engine is retuned to produce 231HP, which is close to a perfect amount for a beginner racing driver (let’s face it - giving a car with more than 300HP to an amateur is like trying to kill him). The car also looks like a proper racing machine, with lowered suspension, racing tires and a spoiler. It still keeps the Base’s FWD, so that there is no need for ESC or even TC - ABS is all that is required, due to strong racing brakes. The transmission is also swapped for a dual clutch, to aid with acceleration in a slightly (?) underpowered engine. Overall a pretty normal FWD sports car.



What if I told you that you can trick your friends and family into thinking that you’re a rich businessman who car afford a new supercar? Well $10k and it’s yours - the Eagle 707 CitySport. While it’s far from a supercar in terms of power output and interior quality, it sure looks like one, and also handles pretty closely, more on that in a moment. It is also a perfect car if you want to have a city daily and a fun weekend car on a budget and in one package - while a 1.6 producing 115HP is not much, it makes the car very economical and doesn’t compromise very good handling.


The Eagle 707 Track gets much closer to a supercar, with an extremely high-revving I5 engine, producing 259HP at 8600RPM, going well up to 10000RPM if you want. While it doesn’t produce much power above 9000-9500RPM (that’s where you should usually shift up), the heightened rev limit aids with extreme engine braking, lets you change gears later (or not at all) during overtaking or close to corners, and just sounds awesome.
Oh, and one important detail… It’s a MF car. Yup. The engine is in the middle, sitting right behind the driver, like in a true supercar, but the power is being sent to the front axle. How? It’s a secret. Why? Because our company doesn’t want young drivers to kill themselves on their first race - that’s why it also has less than 300HP. The MF layout helps to understand how a car with middle-mounted engine would behave, so that the drivers know everything about shifting weight and left-foot-braking when they hop into a real supercar in a higher racing league. But it also has a familiar FWD power delivery, so that most of oversteering mistakes can be easily countered just by flooring the gas pedal.
I must say, it’s a true Eagle Motors car, in almost every aspect - our doctrine is to make light, affordable, oversteery FWD sports cars with low-displacement high-revving NA inline engines. The Eagle 707 fits perfectly into all of this, with a midle-mounted engine thrown on top for good measure. I would be lying if I said that I’m not proud of it, even if it’s just some “weird, inferior, underpowered FWD” for some people.


#119

I’ve just finished streaming the first half of the reviews (link is in the top post)

I know I’m terrible at driving, you don’t need to tell me.


#120

I suspect it was achieved by specifying an AWD drivetrain and sending all the power to the front.


#121

Fun stream, had a gander on catchup, shame I won’t be there to watch it live tomorrow but still.

As for the Seishin and race cars coming before road cars, the road car came before the race car, then the road car was remade from the race car every time I changed the main aesthetic of the car, as tuning road cars is a little more simple then the race car. Or even more awkwardly, the road car came from the race car which came from the road car which came from the 2.1m wheelbase race car Seishin which came from the 2.1m wheelbase road car Seishin.

The race car has a larger centre grill, but yeah you’re right, compared to others, not much change.


#122

IIRC, I put a baffled muffler on the Martlet R because it was way too loud with no muffler (killed comfort and sport competitiveness) and I could not afford the higher engineering time of a straight-through muffler.

And I did not test it in Beam because I don’t have an analogue controller and cannot drive worth anything with the keyboard and high-performance cars–I apologize for the handling problems.

(edit: And the Cat was because the requirement for sport competitiveness, as well as track, suggested to me that even the race variant should be street-legal.)


#123

Most of it is my terrible driving!


#124

I don’t get it, the Aardvark here shows 35.7 months of engineering time :frowning:
I use the standalone version, probably why the difference of versions.
Better luck next time for me then, it was great fun preparing a car for this challenge.
Anyway, great stream @Flamers, watched the whole 3 hours of it. Cheers :heart:

Results

So we had 13 entries, through the process of scrutineering 3 cars unfortunately were voided :frowning:

This left us with 10 cars, all of which I have driven on steam, some I did the laps for off stream during the week so I had enough time to get the results out in a timely manner.

On testing day the sponsor was revealed, the leading drinks manufacturer, VItiaCo. With the agreement to purchase 100 vehicles as well as full spares kits for them the testing began.

For the results I am going to go in reverse order:

10th - Puma

The car sounds amazing, unfortunately it is let down by the lack of grip on power. The car has far too much over steer so it means that unless all 4 wheel are perfectly straight using more than 50% throttle is a real challenge. The car also has problems with the ABS kicking in under heavy braking. It is likely these 2 issues are related and it is probably linked to too smaller tires on the car. This meant that the driver was not able to fully extract the performance from the car in a lap. The difficulty in driving made the VitiaCo reps quite cautious in recommending the vehicle as this was a series aimed at younger drivers.

9th - City E

Overall the car handles very well, the brakes seem to suit the car and stop in a timely fashion without kicking the ABS in too heavily. Unfortunately there is a small amount of over steer when really pushing which can limit the amount of performance you can extract from the car.

It seems that a lack of power was the limiting factor with the car, with a bit more tuning it is likely this car could have been a real competitor.

8th - Julio Mk2

This is my car, so no review :slight_smile:

7th - R85/GT-C

A little too much under steer, especially at low speed makes it difficult to get around corners. The car also feel a little bit under braked which makes big stops a bit of a challenge. The road version of the car could possibly do with a little more work to make it more usable as a daily driver. The styling is not quite striking enough for the VitiaCo reps to buy into.

6th - Eagle 707

At low speeds this car was by far the best car that was entered, providing endless fun around the handling track. So much so that the VitiaCo reps struggled to get the test driver out of the car. Unfortunately the fun that was had at the handling circuit was not matched at the full circuit. The car was unstable at speeds over 130mph which made the VitiaCo reps nervous putting this forward, knowing for well that some of the circuits would have top speeds at, or above, this figure.

5th Rutherford Martlet

In simulation the Martlet was an absolute rocket, providing the fastest simulated lap time. When tested in real life the Martlet dropped down the order considerably, likely due to the difficulty in controlling that amount of power.

It was also noted by the VitiaCo representatives that the car didn’t make a lot of noise which seemed a little strange for a race car.

4th - Luna

The breaking in the Luna is smooth with the ABS only kicking in under extreme heavy braking. The steering is sharp is high speed and gives you the confidence to push allowing you to attract the most out of the car. The traction down low is a little lacking which means the car can get away a little, even with ESC turned on when accelerating out of slow corners. If slightly larger rear tires were used this would more than likely solve this problem.

Overall the Luna was a solid performer however the race car didn’t stand out in any particular category. This was further compounded by the less striking appearance of the race car when compared to some of the other vehicles.

**3rd - Seishin by @RedSawn **

Although not the fastest simulated lap time the driveability when on the track more than made up for this short coming. Being one of the cars that the test drive had most fun in around the race track showed how planted the car was and how much it could be pushed to its limits.

With a good amount of detailing around the front and sides the VitiaCo reps could see the car becoming part of the series, with a little more detailing on the rear it would have been the best car there.

2nd - Viper by @vinodkrishnanr

The rear wheel drive nature of the car allows for drivers with real talent to show there skill. The car corners exceptionally wheel and is very pointable, however under braking the brakes do let it down. The brakes has a large amount of fade which can make heavy stops a real challenge. This meant that the Viper didn’t produce the fastest lap times, either in simulation or real life.

However where the Viper really made up ground was on the handling track where the pointability of the car really showed. Coupled with it’s striking looks and great sound it made for a very strong contender.

1st - Hotshot by @droya

One of the fastest cars, both in simulation and in real life. The Hotshot was actually the fastest car on the day. Whilst it may have been the fastest car it was not the most driveable, at low speed the car can be a real challenge to keep under control.

The VitiaCo representatives will by work together with Droya to refine the car into something that will be nearly as fast but much more driveable as part of this series.

Roundup

I hope you all enjoyed this and it gave you a nice challenge that was hopefully a little different to what you have done before. I am sorry to have to exclude 3 cars but the rules are the rules :frowning:

I enjoyed hosting this and will be hosting more in the future :slight_smile:

#126

Can’t wait to see what challenges you host next.


#127

This is actually my first challenge that I’ve done, i’m really surprised and happy that I won.


#128

Wow, third at my first go, thank you very much. I’ll have to look at the VoD to see the final thoughts.

Looks like I killed my chances at the top spot mostly by trying to fit to old S2000 regulations - i.e, 2000cc max and no turbo. Can only go so fast in a mostly average NA car, especially on a time budget. Perhaps should have tried the Race intake and semi slicks at the least for more simulated time and horsepower.


#129

@flamers which car was your personal favorite?


#130

Welp, I was expecing that - aero in BeamNG works totally different to aero in Automation - I think that the rear wing on the Eagle 707 was producing more lift than downforce in Beam…

On a side note, I wonder if those young drivers will be safe in a car that has more power than some GT4 cars…


#131

Puma being oversteery? What you expected from car made as RWD and lightweight? Thats the reasons why you got electronic, to act as training wheels. Abs blocking? You know that braking isn’t just flooring brake pedal and hoping for best is what real racing drivers do.
Car was designed to be not powerful car being close to Cup car specs to teach young that higher classes aren’t cars like in games people often plays and forget that car isn’t a toy. If you got skill and learn with it, higher classes of cars would be just another step on staircase, but what do i know about cars. F1 or GT3 are probably very easy to drive with this approach of yours.


#132

I mean, as @Elektrycerz just said, a few of the cars have about as much power as a gt4 car sooo…


#133

I wonder how a real Clio Cup car would do here - with 205mm road tires, 217HP and a top speed of 161km/h…


#134

Some of the road cars would be faster it around the track


#135

Having driven Ariel Atoms, M4 GTP’s, Caterham 7’s as well as single seat cars I do have a degree of an idea of what I’m talking about. I’m not saying I’m an expert but I do at least have an idea what they feel like.

A Caterham, whilst it has less power also has no aids to help you and you can pretty easily get a hold of it and be pretty quick in it.

The idea of this wasn’t do build a GT3 car, which are vastly different. It was to build something that would be an initial step into racing, typically for 16-18 year olds. At that age you also have to think that the parents are the people who are funding the drivers and they want it do be safe (as possible)


#136

The aero was defiantly a little off, the sense of lift at ~130mph was a little… Off putting?


#137

So essentially not my car in any way shape or form, got it
