Spend upwards of $600,000 on a Lamborghini Revuelto and you receive a 1,001 hp hybrid V12, scissor doors and a cabin styled like a fighter jet’s cockpit. You also receive, it turns out, a door speaker that’s shared with a Volkswagen Golf’s standard audio system. Before you rush to cancel your Revuelto order, this is simply how the Volkswagen Group operates. Lamborghini sits under Audi, Audi sits under Volkswagen, and a shared parts bin is just how things work.

This isn’t even Lamborghini’s first brush with the bargain end of the automotive parts bin. The Murcielago, for instance, used a climate-control panel shared with the humble Rover 45. The cost of replacing it from Lamborghini is upwards of $2,000, while the equivalent Rover part can be had for a little over $35. This is the catch for owners hoping to cash in on parts bin prices. Anything with a raging bull logo rarely sells at Volkswagen prices. So if you service your Lamborghini through authorised experts, expect the invoice to reflect the badge.

A parts catalogue on Eurospares lists the Revuelto’s front bass loudspeaker under part number 5H0035453, priced at about $40. The same number, as Instagram user brianscustomaudio, found out, turns up against the Golf VIII, Golf R, GTI and the electric ID. Buzz, as well as the newer Temerario. Volkswagen’s own parts store prices it at $25.60, and the unit weighs just 637 grams. Set that against the car’s sticker and the speaker accounts for about 0.004 percent of the bill. It may well be the most democratic component in an otherwise gloriously undemocratic machine.

The pieces that define the Revuelto, namely the carbon-fiber structure and the plug-in hybrid drivetrain, are properly bespoke. Plus paying customers sign up for the V12, which is arguably the best audio system on board. Though, if you are an audiophile, Lamborghini will let you spend $6,000 to spec an upgraded 7-speaker 750W audio system developed by Sonus Faber, with replacement speakers listed on the same parts website for a little over $330 each. We’d argue that it’s probably money well spent if you want bespoke audio to match the headline numbers, unless you’re okay with the fact that somewhere in the door sits a humble speaker from a humble Volkswagen.
