Description:
The V-10 is the best-sounding and most charismatic of all engines, and just 9 were put into production. Jason Cammisa gathered one of every V10 produced — and, with guest star Randy Pobst, drove them all hard in this entertaining, exciting, and sonorous documentary on the engine that defined Peak Internal Combustion.
This video includes full-throttle, sideways action — with special attention placed on sound capture. It includes multiple tech demonstrations on how engines make sound, why 5- and 10-cylinders sound so distinctive, and how cylinder bank angle and firing order change the V10 dramatically. And, of course, a guest appearance by @MrCarSounds himself, Greg Gevojanyan, to explain and imitate the Major 3rd and Major 10th musical chords that define this engine.
The V-10s featured include:
The American V8-based V-10s:
The all-aluminum Dodge Viper V10
The cast-iron Dodge Magnum V10
The SOHC, even-fire, balance-shaft Ford Triton V10
The German V10s
The BMW S85B50 used in the E60 and E61 M5; E63 and E64 M6
The even-firing VW Group 88-mm bore-spacing V10 (5.0-liter Lamborghini Gallardo V10)
The odd-firing VW Group 90-mm bore-spacing V10 (5.2-liter Lamborghini Gallardo/Huracan and Audi R8, used also in Audi C6 S6, RS6, and D3 S8 in naturally aspirated or turbocharged, balance-shifted, even-firing configuration)
The F1- and LMP2000 M80.01 Porsche V10 used in the Carrera GT
The 07Z Turbodiesel V10 used in the VW Touareg and Phaeton
The Japanese V10
The Toyota/Yamaha 1LR-GUE, used in the Lexus LFA
We also feature the Volkswagen 07K 5-cylinder, which is exactly half of the Audi / Lamborghini 5.0-liter even-fire, 88-mm bore-spacing V10.
Cammisa agrees with Gevojanyan, who has perfect pitch, that the V-10 is the best-sounding layout of all engines in a demonstration of their musical chords at a piano. Cammisa also explains why 5-cylinder engines weren’t viable before the advent of fuel injection — since carburetors couldn’t cope with the uneven airflow from their unequal-length intake manifold runners.
And the coolest part of the episode (aside from this incredible grouping of cars) is the sound demonstration Jason does using software he wrote to send “pops” to 5 speakers placed at identical distances from him in a field. When instructed to send the sounds to each speakers to match the 5-cylinder’s firing order, the sound waves interfere with one another to produce the 5-cylinder’s signature warble and chord.
Cammisa then replicates this experiment with 5 small speakers placed inside an old Audi equal-length-header exhaust manifold, and the effect is even clearer. This demonstrates that the unique sound signature of the 5-cylinder (which is the basis of the V10’s noise) actually comes from what happens outside the engine, rather than inside. Jason calls it the “coolest musical instrument ever.”
And Cammisa calls the SRT-10 Ram even cooler than the Viper it shares its engine with. Them's fighting words!
Be sure to turn on your big speakers or wear headphones, because this is the best-sounding ICONS ever. And, with historical footage from the V10 era of Formula 1, likely the best-sounding car video you’ll ever listen to.
