Mercedes motorsport boss Toto Wolff says he feels the latest generation of F1 cars are a 'a mind-blowing display of innovation' despite the various issues encountered by teams during the recent test at Jerez.

The first outing for the distinctive new machines was overshadowed somewhat by a myriad of issues that resulted in limited running for a number of teams - most notably those using Renault engines.

Mercedes by contrast enjoyed a more successful time on track and Wolff admitted that what had been seen in Spain was an indication of F1 pushing the boundaries when it comes to technology.

"When the decision was made a couple of years ago that this new format should be introduced, I thought it was an extremely bold decision and it has not been easy to get where we are today," he said. "However, when you look at what has been produced, these cars really are a mind-blowing display of innovation.

"Formula One is the pinnacle of automotive development, with teams constantly pushing each other and pushing the sport further. Much of this is translate into road cars, so the technology is not only sophisticated, but relevant. I think it's a great concept."

Wolff added that he saw no reason why, over time, the new cars couldn't be a match for the ones they have replaced when it comes to performance.

"What you have to bear in mind is that this is a completely new formula, while the V8 as a concept that had been developed over a number of years," he said. "Even during the course of testing in 2013, lap times were coming down considerably each day, so by the end of this season, I fully expect the cars to be as quick as before."
