Despite the fact that downsizing is a very popular term, there still are manufacturers who don't want to decrease the engine capacity of their cars. Lamborghini is such a brand. They already used the 6.5 liters V12 from the Murciélago for the Aventador and they will also use the Gallardo's 5.2 liters V10 for the Cabrera. We can hear that in the following movie where a test driver is making some laps on the Nürburgring before the future owners of the car are able to do this.
