It looks more like a deployment issue to me i.e. Renault are not yet at the same level, as Mercedes and Ferrari when it comes to coding the deployment parameters for the tracks in racing conditions. There could be a problem with the design of the battery cells of course but I think that's something Renault would pick up on quite quickly.

Looks like Renault are finally starting to catch up with Mercedes and Ferrari. Which is something I've been hoping for since Renault's problems emerged (same with Honda). Ideally I think as fans we'd want all of the manufacturers to be around the same performance levels to have a 4 way fight (one can dream).
Apart for the commercial reasons, wouldn't it hurt Mclaren switching fuel to Petrobras next year, or isn't it a big deal?ripper wrote: ↑05 May 2018, 12:17Renault will bring a new fuel specification during Barcelona GP, McLaren will use it too.

The downside to using new fuels and lubricants means you have to have dyno time to get the most out of the fuel. McLaren doesn't have to spend any effort to develop the engine or the fuel for it, they just use whatever Renault is using. Next year it's going to be harder for them running different fuel because they'll have to pay Renault for the additional dyno time to get the engine working with their fuel.Ground Effect wrote: ↑05 May 2018, 13:46Apart for the commercial reasons, wouldn't it hurt Mclaren switching fuel to Petrobras next year, or isn't it a big deal?ripper wrote: ↑05 May 2018, 12:17Renault will bring a new fuel specification during Barcelona GP, McLaren will use it too.

McLaren won’t pay anything, Petrobras will, and if they want to be in F1 then that’s just part of the cost of entrygodlameroso wrote: ↑05 May 2018, 17:54The downside to using new fuels and lubricants means you have to have dyno time to get the most out of the fuel.

So renault already started to make excuses for not updating the engine, or for their lack of reliability. I think Renault is done, if you can't find a way to improve your engine in almost 2 years... what can we say?gandharva wrote: ↑18 May 2018, 11:22Reliability concern delaying key Renault engine update
On the other hand... I'm not really surprised to read this.

The news is sure to frustrate customers teams Red Bull and McLaren, but Renault are currently not seeing the right dyno figures come back with the MGU-K element of the power unit.
“It’s clear we have to work on the weight and this is one solution,” Renault Sport engine technical director Remi Taffin told Motorsport.com.
“That’s why we did not rush into running that solution. There is no clear target of when. I would more say when it’s ready we will get into it.
“It’s reliability, it’s being able to get that MGU-K running for what we need to run through.”
Renault are still planning to introduce a partial engine upgrade at the Canadian Grand Prix, which would be a third of the way through the 2018 season.
