Antonio Giovinazzi believes Sauber has made a "big step” between Formula 1’s tw𒉰o in-season tests in 2018, after he got back behind the wheel of the C37 in Hungary. 

The Ferrari junior drove for the Italian squad on Tuesday before taking over from Sauber regular Marcus Ericsson on Wednesday, following on from 𝓰his recent FP1 outings at the Germa🦩n and Hungarian Grands Prix.

Giovinazzi, who also appeared for both teams in the first in-season test in Barcelona, ꦉhad already felt a “dramatic” improvement in Ferrari’s latest challenger, while he was also impressed by the progress made by Sauber, which has recorded points finishes in all but four races s🌜ince May’s Spanish Grand Prix. 

“I think the t♓eam is doing a fantastic job,” Giovinazz💧i said. “In FP1 it’s really difficult to see the difference. 

“But compared to rookie test I🎶 did in Barcelona, compared to today, the cꦓar is really a big step in front.

"I’m really happy for 🧸this, they’re doing a fan🦄tastic job, happy with the car and the team.”

When asked where the gains were ဣmost notable, he replied: “Just I think downforce overall. Just better everywhere, braking stability, just everywhere.”

Giov♏inazzi set the pace on the opening day of the test at the Hung✤aroring, before finishing Wednesday’s run in the Sauber with a time two seconds slower than he managed for Ferrari on the same Hypersoft compound. 

💎Comparing his headline times from both days,൩ Giovinazzi noted the large performance gaps between Ferrari and Sauber. 

“Of course it’s another really big step,🃏 two seconds from the lap I did yesterday. I think also t♋hey did a big improvement from the beginning of the year and I spoke about the rookie test in Barcelona.

"So I think everyone is developingᩚᩚᩚᩚᩚᩚ⁤⁤⁤⁤ᩚ⁤⁤⁤⁤ᩚ⁤⁤⁤⁤ᩚ𒀱ᩚᩚᩚ the car but you see the difference compared to Ferrari.”

Giovinazzi added he was keen to i💫mpres🌌s both the Scuderia and Sauber with the Italian aiming for a return to the F1 grid in 2019, having taken part in the opening two races of last season for the Swiss squad as stand-in for the injured Pascal Wehrlein. 

“For now I need just to do what I’m doing, drive a car, I think was two positive days for myself. Now we’ll see,” he explained. "I still have 4 FP1s with Sauber, ಞat the end of the year I hope I can have the seat I want.

"But because I did a good job it is not for sure I will have the seat next year, everything will change, what I will do is just do my be꧒st and will see if it will happen or not."
