Why Ferrari and Aston Martin never made a v10?

Ferrari and Aston Martin have historically focused on their respective V8 and V12 engine architectures, which align with their performance philosophies and brand identities. Ferrari opted for V8s and V12s to emphasize high revving and power delivery characteristics, while Aston Martin leveraged its V8 and V12 engines for a blend of performance and luxury. Additionally, the V10 configuration was less popular in road cars, with manufacturers like Lamborghini and Audi exploring it primarily for specific models, leaving Ferrari and Aston Martin to prioritize their established engine designs.
