What occured in British motorsport in 2019

  What occured in British motorsport in 2019 Much of our racing tends to fly under the radar. Here's this year's key notesIn truth, the 2019 season has been a mixed affair. External pressures weigh heavily on the sport and participants’ ability to commit time and money to it remains a major factor. The groundswell of opinion against fossil fuels, noise, safety and litigation concerns, a shortage of volunteer officials and even Brexit uncertainty have all impacted the sport to some extent.

In a motor vehicle, the powertrain or powerplant comprises the main components that generate power and deliver that power to the road surface, water, or air. This includes the engine, transmission, drive shafts, differentials, and the final drive

These are tricky times for Formula 1 teams. The white-heat intensity of another busy season is upon them, but more than usual they will be diverted by what comes next. The revolutionary new chassis regulations set for 2021 require a clean-sheet design approach and are a huge drain on time and resources.

For Mercedes, Ferrari and Red Bull, there are titles to be won while ensuring that balls aren’t dropped for the impending new era. For the others, new rules offer a rare and golden chance to gain a big chunk of competitive ground – but they can’t afford to forget the present, either. It’s a multi-million-dollar juggling act.

Racing lines: Autocar meets... Alice Powell

  Racing lines: Autocar meets... Alice Powell Five years ago, Alice Powell's racing career was fading. Now the all-female W Series has thrown her a lifeline. We sit down for a chatPowell’s single-seater career petered out in 2014 despite her showing promise in GP3 (now FIA F3). Why? Money, of course. Why else? Since then she’s mostly coached young racers as well as putting in shifts for Dad. “I just do the rubbish jobs, fetching and carrying,” she says. “It’s quite good for fitness actually.

The powertrain (or power unit as it is sometimes known) comprises of the engine, two Energy Recovery Systems (ERS) and an Energy Store. A term used to describe the movement of an F 1 car around an imaginary vertical axis through the centre of the car.

These were the five key pillars Formula 1 focused on when it presented its vision for the future to the F 1 is open to making tweaks. There is an understanding that some teams might have better Claire Williams said “the likelihood of Williams’ survival in the medium or long term is looking pretty

“We don’t want to sacrifice 2020 to get a better start for 2021,” said McLaren team principal Andreas Seidl at the launch of the MCL35. The British outfit enjoyed a much-needed rejuvenation last season, finishing fourth in the teams’ standings as best of the rest behind the ‘big three’. That hard-earned momentum must not be lost, especially for an independent team that has to pay for its engines.

“We want to make the next step in 2020,” continued Seidl. “Similar to everyone else, we want a strong start to the season, because that might make it easier to switch some resources to the next car.”

Beyond 2021, F1 is looking further into the future, to its next-generation power solution, which is due in 2025 as the wider world’s zero-emissions targets move closer. Last week, we touched upon the drive towards electrification and how F1 might eventually be forced to embrace it. But that’s not how leading figures necessarily see it. There’s a strong belief in the combustion engine; one fascinating stream of research, for example, revolves around super-efficient, high-revving, small-capacity two strokes.

Innovation Planets are showcase areas where OEMs and suppliers can discover the best applications for composites in their market. “We are positioned to capitalize on the changing landscape with a strong product portfolio that covers various powertrain types.

“There are lots of technologies to consider,” said McLaren’s new technical director, James Key. “Clearly it has got to be relevant, but there are alternatives [to electrification]. The energy density of fuel is incredibly high. If you could make that low- or preferably zero-emissions using a different type of fuel, all the technologies around combustion engines are there. Of all the industries in the world, F1, with the speed and amount of development that goes on, is well placed to find new methods of propulsion for the future.”

F1 leading, rather than following, automotive power needs: what a great way to protect motorsport from legislation that could banish it into extinction.

Electric BMW 7 Series due in 2022 .
Like the next Jaguar XJ, the BMW 7 Series will be available as an EVPerformance and battery details have yet to be released but it’s likely that the 7 Series EV will use a similar powertrain to the BMW iX3. The iX3 has two electric motors that provide all-wheel drive and are linked to a 70kWh battery pack for an output of 532bhp. Given that all the power in electric cars is available instantly, we expect the iX3 and the 7 Series to be blisteringly fast in a straight line.
