Engine & Vehicle Testing

From small engines to large vehicles, develop better, safer, more durable products that meet regulatory requirements with testing from SGS.

Test your vehicle and engine powertrains under extreme environmental conditions at sea level, at altitude and even at simulated altitude. At SGS, we have cutting-edge facilities and laboratories all over the world where we are using our own patented technology.

Our experts can help with everything from the most basic tests for small engines to custom-designed, complex tests for larger engines and vehicles. As an independent body, we can complement your existing powertrain testing program or undertake full testing services, including vehicle development and performance testing, if required.
