Here's why the Valkyrie matters (hint: it's not downforce)

[12,000 RPM]

Just 1000 RPM short of unarguable greatness.

Hoping with more electrification we can get more engines like this (though an 11K RPM car valvetrain is tricky)

Cool, the engine is structural. Like an old tractor.

Cool, the engine is structural. Like an old tractor.

You mean like an old Lotus 49.

The Lotus 49 is among the most significant and beloved cars in the history of Formula One racing.  Its technical significance stems from the fact that, when it was introduced in 1967, the Lotus 49 was the first successful Formula One car to feature the engine as a fully-stressed, structural component of the chassis.

Fifty years of progress...
