No, but that's what Juntos is meaning
Both Prologues the car has run at it's been "within a second" of Toyota, yet it hasn't been even remotely close during the one and only event.
Also, if you think about it - they knew the engine was "over 100hp down" during the first prologue and they still thought they were within a second of Toyota? How much of this is optimism, and how much of this is Prost GP attempts to sell sponsorship/cars?
