Porsche Motorsport completed the first shakedown of its LMDh prototype just a few days ago on his Weissach test track. A first contact with the asphalt in which Porsche showed some details of its new car as a preview. Now, at the gates of the dispute of the 24 Hours of Daytona, the Stuttgart brand has shown its LMDh in all its splendor, also confirming the use of un V8 twin-turbo engine as the heart of this prototype. This same engine will give life to the Audi LMDh prototype.
Own Thomas Laudenbach, vice president of Porsche Motosport, has been in charge of confirming the use of this V8 in the VAG Group prototypes to compete in the queen class of the WEC and IMSA: «We had different options to choose motor because we have a range of products with very promising units. Finally, noWe have decided on the twin-turbocharged V8 engine because it offers the best combination of performance, weight and cost. that we have been able to find. The start of the track tests is a very important step for the project.”

Despite the fact that one of the great managers of Porsche Motorsport has been in charge of confirming the use of this V8 biturbo engine, the truth is that the volume of information about the chosen power unit is minimal. Yes it is known that the propellant has to have weighing at least 180 kilograms, a power below the 680 hp that has been set as the performance limit between the combustion engine and the standard hybrid system and a rev range that does not exceed the top of 10,000 rpm.
Within the parameters established by the regulations, the V8 biturbo engine present in the range of Porsche vehicles is the 4.0-litre direct injection V8 engine offered in the Porsche Cayenne and Panamera range. However, this is not a very good ‘hint’, as this engine is sold in different power levels. In the Cayenne GTS it offers 460 hp, while in the Cayenne Turbo it reaches 550 hp. Among its different versions, in the Panamera Turbo S it yields nothing more and nothing less than 630 CV.
Leaving aside the engine that the LMDh prototypes of Porsche and the rest of the VAG Group firms will use, the photos that have accompanied this confirmation have allowed see some details of the silhouette of the Porsche LMDh, especially in regard to the rear spoiler. And although it is true that this component will evolve over the coming months, the first solution used by Porsche it goes through a rear wing with two very small planes with the endplates integrated into the bodywork.
