Kovalainen: CT03 more difficult to drive
19 April 2013 – Heikki Kovalainen has explained that Caterham’s CT03 chassis is more challenging to drive than its predecessor, with the former Grand Prix winner experiencing a "knife edge" balance throughout the opening practice session for the Bahrain Grand Prix.
The Finn, who has returned to the team as a reserve, tested the original car en route to 20th place, while Charles Pic went half a second quicker with a range of upgrades.
"It's more unbalanced than I experienced last year. It's more difficult to drive and more inconsistent. It is not a surprise because of the way that the car has been modified in terms of ride height and stiffness."
Kovalainen believes a better car set-up has the ability to yield a significant amount of lap time, but the 31-year-old admits work needs to be done to the rear of the car.
"Part of it is solvable with set-up, but when we improve and put upgrades on, the one area that we need to improve is the back end," he said. "It needs to be stronger."
