Honda has brought forward the introduction of the second specification of its 2019 Formula One engine to this weekend's Azerbaijan Grand Prix
The decision was made after a quality control issue was discovered as the reason for a problem on Daniil Kvyat's Toro Rosso at the Chinese Grand Prix. The Spec-2 Honda engine promises "improved durability and life and better reliability" as well as "a slight improvement in performance" and will be fitted to both Red Bulls and both Toro Rossos in Baku.
Under Formula One's sporting regulations, drivers are limited to just three engines per season before receiving a grid penalty.
