F1 » Renault seeking ‘at least five wins’ in F1 2015


richard: for goodness sake! do some research! the mercs advantage is in their pu. the collection and rapid release of electrical energy! and yes, in the v8s, the merc gave 880 bhp, the ferrari 850 bhp and the renault 800-820 bhp! you mightnt like it, but those are simple facts.
Here's some research for you...in the V8 era, not a single one of the engine manufacturers came anywhere near to cracking 800bhp, so where you're plucking a figure of 880bhp from is bewildering. I suggest you read the 'last of the V8s' article on racecar-engineering dot com my good man. Although, you may not like it, as it states the facts. The most powerful 3.0l V10 engines were pumping out around 960bhp. With the displacement reduced by 20%, the top end power took a proportional decrease to go with it. Then if you introduce the 19,000 and 18,000rpm limits, you're left with V8 engines that produce around 750bhp. V8 development was also frozen.

As for your statement that the 2014 Merc powertrain advantage was in their 'pu' (I assume you mean their ERS systems), again you're wide of the mark. Due to the strength of the ICE, Mercedes ran their ERS systems relatively conservatively, with plenty of scope left for extra headroom. This is the area where they will make their gains. For a demonstration of just how much more powerful the Merc ICE is compared to the others, you only have to look back to Canada last season. Despite having zero electrical boost, Rosberg was able to hold onto second place on a circuit where horsepower plays a huge role.

richard:
DennisKwok: So, Renault's aim is to be only 30bhp down on Mercedes compared to where they at the end of 2014? Ok, so if the rumours coming out of Brixworth are true, that leaves Renault the best part of 80bhp down come Melbourne. Theoretically, Renault will be even further behind in terms of bhp than they were last year.
of course rumours mean nothing! however, when renault engines last won the wdc (for 4 years!) they were 80 bhp down on the merc. that didnt stop them, did it?
Rumours do mean something if they have substance. It's been widely known that Mercs bhp advantage mainly comes from their ICE due to the unique spilt turbo arrangement and they still have lots of scope left to improve their ERS systems and software integration. Also, are you seriously saying that in the 2.4l V8 era, the Renault engine was 80bhp down on the Mercedes? Don't be silly.

F1 » Williams F1 recruits Robson from McLaren


Robson was Jenson's new race engineer for last year, after Andreas Jacobsen left Mclaren. This was party why Jenson struggled in the first half of last year in comparison to Magnussen. They started working together much better in the second half and the results came as the car got better. Now Jenson is going to have to start another relationship for the second season in a row. Still, I suppose it puts him and Alonso on a more equal footing.
