What happened: Christian Horner says Red Bull was unprepared for some of Adrian Newey's most revolutionary ideas in their early years together. The question now is whether Aston Martin faces a similar challenge.

Why it matters: The comparison turns on how Aston Martin puts Newey's ideas into practice. Newey recently pushed back on Horner's separate 'abandon ship' claim.

What to watch: Aston Martin's future car development will provide a clearer test of the comparison.
