Introduction and Background The modern recreational vehicle (RV) and motorhome industry relies extensively on commercial off-the-shelf (COTS) truck and van chassis platforms supplied by major OEMs such as Ford, General Motors, and Stellantis (Ram). Popular base platforms include the  Ford Transit, E-Series 350/450/550/600,  Ram ProMaster and Ram 3500–5500 cab chassis,…

When it comes to designing cars, whether for everyday use or high-performance sports vehicles, every detail matters. One area that can significantly impact a car’s performance and efficiency is its aerodynamics—the way air flows around and over the vehicle. As car manufacturers push for better fuel economy, longer electric vehicle…

The e-powertrain is the heart of an electric vehicle (EV), comprising the motor, battery, inverter, and supporting systems that power the vehicle. As EV adoption grows, designing efficient and high-performing e-powertrain systems has become a critical focus for manufacturers. Achieving the right balance of range, energy efficiency, and thermal performance…

Designing power cylinder components for internal combustion engines, such as pistons, piston pins, connecting rods, and crankshafts, involves much more than putting parts together to make a machine run. These components are responsible for the engine’s fundamental operations—converting fuel into motion—and face intense heat, pressure, and forces while doing so.…

Modern vehicles are marvels of engineering, built with advanced technologies that seamlessly work together to deliver exceptional performance, efficiency, and safety. At the heart of these technologies lies control algorithm development, the sophisticated software that governs various vehicle systems to ensure they operate optimally under diverse driving conditions. Control algorithms…

In the world of engineering, the ability to predict how fluids and gasses behave in a system is critical to optimizing designs and improving performance. This is where Computational Fluid Dynamics (CFD) comes into play. At Caliber Technologies, we leverage the power of CFD to help businesses across various industries…

The chassis or frame is the heart of any truck, supporting the engine, body, wheels, and cargo. It is responsible for withstanding immense stress, heavy loads, and long-distance travel while maintaining strength, stability, and safety. When designing a truck chassis, engineers must carefully balance various factors to ensure the vehicle…

Heating, Ventilation, and Air Conditioning (HVAC) systems are essential for creating a comfortable interior environment in vehicles. Whether you’re driving through scorching summer heat or braving freezing winter temperatures, a well-functioning HVAC system ensures that the cabin remains comfortable, safe, and conducive for all occupants. Achieving better HVAC performance in…

In today’s engineering world, structural simulation has become a game-changer for companies looking to create strong, reliable, and efficient designs. At Caliber Technologies, we use advanced techniques to simulate how structures and parts will hold up under various conditions—such as weight, stress, and temperature—before they are even built. This approach,…

Suspension systems play a crucial role in determining how a vehicle performs on the road. Whether you’re driving on a smooth highway or navigating rough terrain, the suspension system ensures that the vehicle remains stable, comfortable, and easy to control. It is a key component of vehicle dynamics, which refers…
