From the team
With the upcoming update the engines in Homebrew have been revisited and received a major overhaul. The behavior/appearance of the current in-game engines has improved and a couple new engines will be introduced. In addition to this we've also fine-tuned the existing transmission and added a new, smaller transmission as well. Below you can read what it's all about.
Engine improvements and new engines
While working on wheel physics we quickly realized that engines needed immediate attention. From now on all engines use the correct torque and the force is divided among the wheels correctly.
In addition to behavior changes we've also improved the visuals of the existing engines as well. Below you can find a full list of all the new and existing ones with their (new) corresponding stats.
Falcon 6
If you've played HB14 you're definitely familiar with this one. Its visuals have been improved and changes have been made to ensure that its performance is more accurate than ever. Below you can find the new performance values.
- 169 Nm at redline (5500 RPM)
- 212 Nm heap (1500 RPM-2600 RPM)
- 100 Nm at idle (750 RPM)
- 0,019 L/s (fuel consumption)
- +- 120 kg (weight)
M14P Radial Engine
With changes being made to propellers and the falcon engine we decided to get our hands dirty and work on this engine too. Better visuals and modifications of the underlying torque curve have unlocked its full potential.
- 651 Nm at redline (3000 RPM)
- 732 Nm heap (1000 RPM-2700 RPM)
- 450 Nm at idle (750 RPM)
- 0,023 L/s (fuel consumption)
- +- 214 kg (weight)
Electric motor
Although this motor hasn't changed visually the performance has been modified meaning that the behavior has changed. Here are the core values.
- 0.03Nm at redline (10000 RPM)
- 0.458 Nm heap (0 RPM-250 RPM)
- +- 20 kg (weight)
Tuk tuk
This one has been in-game for a while now, but after additional testing we quickly realized that its values weren't correct. Although the engine is quite weak, it still looks damn awesome and will help you stay in the air with your glider and stuff.
- 5,33 Nm at redline (1040 RPM)
- 5,33 Nm heap (100 RPM-1000 RPM)
- 2 Nm at idle (250 RPM)
- 0,001 L/s (fuel consumption)
- +- 20 kg (weight)
Falcon 6D
Diesel fuel is one of the most efficient and energy dense fuels available today. Because of the way the fuel is burnt, this engine type provides far more torque to the driveshaft than its gasoline counterpart.
- 210 Nm at redline (2900 RPM)
- 421 Nm heap (1200 RPM-1750 RPM)
- 210 Nm at idle (550 RPM)
- 0,006 L/s (fuel consumption)
- +- 260 kg (weight)
Kart engine
We know that a lot of you guys love to build small vehicles and so do we. Therefore a new, compact engine that can be used on karts, bikes, quads and all other kinds of vehicles has been added.
- 20 Nm at redline (3600 RPM)
- 20 Nm heap (1000 RPM-3600 RPM)
- 20 Nm at idle (1000 RPM)
- 0,001 L/s (fuel consumption)
- +- 26 kg (weight)
D22 Twister
This 1,2 ton beast is ready for some heavy duty, since it delivers a great amount of torque it will come in extremely handy on trucks and boats. By running on diesel means that it can easily out-tow gas powered vehicles while delivering a great fuel economy. Be aware though and keep in mind that it's weight will affect the behavior of your vehicle significantly.
- 1250 Nm at redline (2200 RPM)
- 2237 Nm heap (1200 RPM-1500 RPM)
- 1200 Nm at idle (700 RPM)
- 0,033 L/s (fuel consumption)
- 1200 kg (weight)
Outboard motor
We've mentioned the addition of this one in a previous post, but haven't discussed the stats yet. So without further ado here they are:
- 400 Nm at redline (2200 RPM)
- 462 Nm heap (1200 RPM-1500 RPM)
- 200 Nm at idle (700 RPM)
- 0,018 L/s (fuel consumption)
- 200 kg (weight)
Car transmission (+- 100 kg)
The current in-game transmission has been worked on and now has 13 (+ an additional one for reverse) gears at your disposal. In addition the transmission als has a new set gear input; this allows you to go go from gear 5 to gear 9 for example without having to go through all the gears first.
Small car transmission (+- 30 kg)
For the purpose of building smaller craft we've added in a more compact transmission with 6 gears (+ an additional one for reverse) and a set gear input as well. From our experience this will allow you to have slicker and better handling vehicles.
What's next?
The next posts will focus on some effects that have been added, improvements to the tutorial and additional bug fixes that haven't been mentioned yet. As always we'd like to thank all of you guys for supporting us throughout the development and we're looking forward to hearing your thoughts on the new build.
DREAM - BUILD - ENJOY
