Wolff: Mercedes lack the money to keep pace with rivals' car development under F1 cost cap

Mercedes team principal Toto Wolff says the team "haven't got the money" to develop their car at the same rhythm as championship rivals. Speaking to BBC Sport, Wolff called the season a development race and said the ride has been "a bit tougher than at the beginning of the year." Each rival upgrade can be worth a couple of tenths per lap — a margin that reshapes the competitive order.
