Так у них максималка 225 кмч) Ф1 с такой скоростью за SC ездит :D

Думаю эти две серии никогда нельзя будет сравнивать)

Опять же, дико интересно, насколько их нельзя сравнивать в смысле скорости. Ну, в итоге да, Формулу-Е можно использовать в качестве зеленого СК для Ф-1.

а не плохая идея :D

и как раз, остановились бы на том, что зеленый SC остался единственным зеленым элементом в Ф1)))

Formula E's new era explained

Formula E will feature a variety of technical offerings as the all-electric series widens its remit in season two. GARY WATKINS explains why such varied ideas are being explored, and what it could mean

By Gary Watkins Special contributor

New regulations mean new technical solutions. And in the brave new world of the Formula E Championship that means a variety of different solutions.

The freeing up of the powertrain regulations for the second season of the FIA's electric-vehicle series will result in a number of configurations racing against each other when the championship begins in Beijing in mid-October.

Some of the Formula E machines will have one electric motor and some will have two, while the cars from the 10 teams are set to race with between one and five gears.

The reasons for the different approaches are three-fold: a cap on the power of the motor remains; the resources available to the teams vary; and, perhaps most important of all, no one has the definitive answers in what is the world's first EV racing series.

The solutions stretch from Team Aguri's decision to stick with the spec one-make package of season one and retain the McLaren Electronic Systems motor and five-speed Hewland gearbox, to that of the DS Virgin Racing squad.

The British team, which has linked up with Citroen sub-brand DS, hasn't disclosed details, but firmly hints it has gone further than its rivals. Expect it to announce a twin-motor set-up with only one gear, really a differential, when it does reveal all.

Aguri team boss Mark Preston, a former principal designer at the McLaren Formula 1 squad, points out that Formula E is unique in international motorsport in that power is limited and not just the energy allowed to create that power.

"In no series using the internal combustion engine is power limited, but in this series we are limiting power, and power means top speed," he says. "As long as you are not torque-limited out of the corners, you are not limited by the powertrain as such.

"Our basic calculation was that the races are going to be most likely the same number of laps and the energy from the battery is staying the same.

"If you look at the difference in the energy useage across the grid in season one, there was a bigger margin than the efficiency gains you are going to be able to make with the motor in season two.

"If you put all that together and look at the resources required to develop a new powertrain, we thought, you know what, it's probably better to optimise this car for season two."

The big question is whether the limitations presented by the twin caps on power and energy - maximum race power is being raised from 150kW to 170kW, while the energy from the battery remains at 28kW/h - will allow the innovators on the grid to steal an advantage in season two. DS Virgin Racing chief technical officer Sylvain Filippi thinks so.

"In theory, if you are power limited you can only go so far," he says. "But in reality it's the opposite. Gains in efficiency will translate directly into performance. The more efficient you are, the less lifting [coasting to conserve energy] you will have to do.

"That is why our philosophy has been to redesign the powertrain completely. We believe we have made significant gains in efficiency that will translate into performance. The question is how much have we gained in comparison to the others?"

There is another reason for opting for revolution rather than evolution, reveals Filippi. Formula E is on a five-season course to abandon the practice of drivers swapping cars mid-race, which will mean significant changes in the technology between now and then.

"What we learn this year, we can apply through successive seasons in the future," he explains.

Roger Griffiths, boss of the Andretti squad, has similar thoughts.

"At some point in the future we are going to be moving to much higher numbers in terms of power and energy," he says. "We will need to edge our way up to that. When we get to one-car races and much freer regulations, we won't be able to make that step all at once, whether it be for reasons of finance, technical resources or time."

The instant torque provided by an electric motor would appear to point to a gearbox-less set-up as being the optimum. There is an obvious weight advantage and no time-consuming gearchanges are necessary.

But it is not as simple as that in Formula E. The rules dictate that the motor or motors must drive the rear axle through a conventional mechanical differential.

That negates much of the benefit of running without a gearbox, and is the reason why the FIA demanded a differential. Direct drive from each of two motors would have allowed for torque vectoring - the process of varying the amount of power going to each wheel - to aid handling, a complexity that the governing body was keen to avoid in the fledging series.

"That was the death of the two-motor solution for us," says Griffiths, whose Andretti cars will be running a single motor developed in the US by Houston Mechatronics and a four-speed Hewland gearbox in 2015/16.

"The nice thing about two motors is that you can control them independently for torque vectoring."

The other factor is that the eight Formula E manufacturers – really seven of the teams plus Renault – that registered for the right to produce their own powertrains for 2015/16 have to work within the existing architecture of the Dallara-built SRT_01E chassis.

Look at pictures of the latest Formula E contenders testing at Donington Park this week, and you won't spot any external differences between them and the cars that raced in season one.

"If you want your motor package to be nice and small with a very low centre of gravity, you end up with a high-speed motor that needs more gears," says Griffiths, who points out that fifth gear was used infrequently last season.

Achieving the necessary torque to dispense with the gearbox would require a larger diameter motor. That is why those running without a conventional gearbox or with fewer gears – Renault, technical partner of the e.dams team, has opted for two – have gone for a twin-motor set-up. One motor would be a lighter way to achieve the same torque figures, but would come with a centre of gravity disadvantage.

The Nextev squad, which won the inaugural Formula E title with Nelson Piquet Jr as Team China Racing, suggests there is also a cooling advantage of running the twin motor set-up for which it has opted.

Renault, which has developed its new powertrain at the same facility that produces its F1 engines, has chosen a halfway-house solution. It is running two motors and two gears.

"It's a question of risk assessment," says Vincent Gaillardot, Renault's Formula E programme manager.

"In this first season of open powertrains do you want to really go for a fully optimised solution in terms of weight and packaging and miss something that causes some trouble, or do something where you have a bit more margin.

"We have decided not to take any risks and go for a gearbox with different speeds, but how we will use it through the season is not defined yet."

The Abt team, which is supported by Audi Sport, also appears to have gone for a compromise. It has yet to release details of its package, but is known to be running a three-speed gearbox and believed to have a single motor.

The one motor, four-speed approach will be the most common on the grid in 2015/16. As well as Andretti, Mahindra and Venturi, which is supplying its powertrain to Dragon Racing, have gone down this route.

Mahindra has worked with McLaren to produce an uprated version of the original Formula E motor, while electric-vehicle specialist Venturi, which holds the land speed record for electric-powered cars, has developed its own with more torque and a broader rev range. All are using modifications of last year's Hewland gearbox.

Any teams that do not get on top of their technology have the option to revert to 2014/15 specification and run in the same configuration as Aguri. They have until August 30, the day before the cars leave for China, to make that call.

All 10 Formula E teams were present at the first of three two-day official tests at Donington Park at the start of this week, although Andretti failed to complete a timed lap and Trulli didn't make it out onto the track. The timesheets from the two days were not particularly revealing, but then they were never going to be.

The top times were all set with 200kW qualifying power, which has been maintained from season one. The real differences will appear when the Formula E cars start racing, and racing at a higher power figure than before with the same amount of energy per car. That's when the efficiency gains will become apparent.

"The good thing about Formula E is that we don't know all the answers," says Preston. "Only time will tell who is right, and that is going to be fascinating."
