Lewis Hamilton lamented the "worst" cars, but Mercedes said his driving style wasn't suited to the ground-effect cars.

With F1’s current regulations now in their fourth year, the performance gaps that gave front-runners comfortable advantages are shrinking fast. Teams that were once struggling to keep pace have had enough time with these cars to catch up on the learning curve. (See: Ferrari and McLaren’s surge last year .)

The British F1 star has been taking Italian lessons, has his motorhome parked next to Enzo Ferrari’s house and is immersing himself in the culture of the Scuderia as he eyes a record-breaking eighth title this year.
