The Ferrari 812 Superfast is renowned for its breathtaking performance, a significant part of which is attributed to its мощный engine. When discussing supercars like the 812, the term “horsepower” immediately comes to mind, representing the sheer power at the driver’s disposal. But how do we measure and understand the performance and environmental impact of such high-performance vehicles in a standardized way? This is where vehicle testing procedures come into play.
Historically, the automotive industry relied on the New European Driving Cycle (NEDC) to assess fuel consumption and emissions. Introduced in various stages since the 1970s, NEDC aimed to provide a repeatable laboratory test for comparing different vehicles. However, the NEDC protocol, with its low average speed of just 34 km/h, gentle accelerations, and a maximum speed of 120 km/h, increasingly became less representative of real-world driving conditions, especially for high-performance cars like a Ferrari 812. Imagine unleashing the full potential of a Ferrari 812 Horsepower engine within the confines of the NEDC’s limited parameters – it simply doesn’t reflect the dynamic capabilities of such a machine.

Recognizing the discrepancies between NEDC results and actual driving experiences, especially with modern, powerful vehicles, the Worldwide harmonized Light-duty vehicle Test Procedure (WLTP) was introduced in Europe in September 2017. WLTP aims to provide consumers with more realistic data that better reflects everyday vehicle use. The WLTP procedure utilizes new Worldwide harmonized Light-duty vehicle Test Cycles (WLTC), characterized by a more dynamic driving profile with more substantial acceleration and braking phases. The maximum speed in WLTP increases to 131.3 km/h, the average speed is raised to 46.5 km/h, and the test duration extends to 30 minutes, covering a distance of 23.25 kilometers – double that of the NEDC.
The WLTP test cycle is divided into four parts based on speed: Low, Medium, High, and Extra-high, simulating urban, suburban, extra-urban roads, and motorway driving. This comprehensive approach provides a more accurate assessment of fuel consumption and emissions across a broader spectrum of driving conditions. Furthermore, WLTP considers vehicle-specific optional equipment that affects aerodynamics, rolling resistance, and vehicle mass. This means that the CO2 value produced by the WLTP test is more closely aligned with the actual characteristics of an individual vehicle, whether it’s a standard model or a high-performance variant boasting significant horsepower.

In conclusion, while figures like “ferrari 812 horsepower” capture the essence of a vehicle’s raw power, standardized tests like WLTP are crucial for understanding the broader performance and environmental impact of vehicles across different driving scenarios. WLTP represents a significant step forward from NEDC, offering a more realistic and relevant evaluation of fuel consumption and emissions, even for high-performance machines that fully utilize their impressive horsepower on the open road and track.
