Bassooo....go..go!

[WUff1]

Andreucci seems to get used to his new car now, with two more stage wins today (out of 3) - or his team found the optimal settings of the car.

Basso had before him after the first day almost one minute advantage, so today he does not need to drive on a limit.

Nucita retired...

If I understand well, his car caught fire.

[Ucci]

Nucita had some electrical issues, the inside of the car start to overheat and the fire extinguisher was put in operation...Nucita had a slight poisoning due to smoke, but nothing seriously....Anyway, he is the biggest positive surprise of this rally!! Young guy has a bright future in front of him. Do not forget-he was driving a private 207 S2000.
Basso- very routinely, without any problem whatsoever-victory with a huge margin, could be even bigger if he would push more on the second day. Well done Fiesta R5 & the team, which prepared gas powered car.
Scandola-second place, but he won just one stage, he had no chance against Basso.
Paolo Andreucci-definitely one of the lowest points in his career. On his home rally we honestly all expected victory and nothing else, but this result is showing two things: or Andreucci is to old or P208 R5 is a failed project. Don't be tempted by today's stages victories-Basso was on a ''cruising mode''.

Like I told before, Basso with CNG car is not comparable thing as we dont know rules for his car. But Andreucci was slower than Scandola, which is comparable...

Below is a comparison a Finnish motorsport magazine made 6 years ago (Vauhdin Maailma 3/2008) between a CNG Evo (Manfred Stohl) and a petrol Evo, both with a 32 mm restrictor. The petrol had a peak torque of 566 Nm @ 3290 rpm compared to CNG Evo’s 532 Nm @ 3440 rpm (94%). Peak power for petrol Evo was 276 PS @ 3650 rpm compared to CNG’s 263 PS @ 3520 (95,5%). Both was measured in the same dyno.

The CNG evo has two 90 litre tanks, one behind the seats and another one in the trunk. I don’t know how big the Evo’s fuel tank is but calculating with 70 litre and about 0,75 kg/litre density for petrol would give a result for 52,5 kg for a full tank. The CNG’s density is about 0,42 kg/litre and the weight of 180 litre would be 75,6 kg.

The weight of the cars was not mention but they said that the CNG evo is “few tens of kg” heavier than the petrol evo. Jani Paasonen who tested the CNG evo said that on lower revs there are less torque but the curve increase rapidly and on higher revs the power & torque difference is not noticeable when driving. The response to the throttle have a little delay. Also the torque band is narrower.
