F1 LIVE: Lewis Hamilton fears confirmed by Red Bull chief as Mercedes launch investigation | F1 | Sport

Christian Horner has revealed that Red Bull have been developing their 2024 challenger since the midpoint of this year.

It comes after Mercedes driver Lewis Hamilton suggested that Red Bull had not touched their existing car since the summer due to their sheer dominance over the rest of the field.

Horner said: « Thankfully, we had a good base to start because if we’d have been consumed with the very limited amount of wind tunnel we had in terms of developing RB19, it would really compromise us very badly on to RB20.

« Because we had a great starting block with ’19 enabled us to apply the limited amount of resource that we had available to RB20 reasonably early for us, while spinning both plates. That’s why development has been very frugal on this car really since the middle of the year. »
