IMSA: DeltaWing explains latest development updates, gearbox and differential

3 Comments

In an effort to improve overall performance, the DeltaWing Racing Cars team has made numerous updates to the revolutionary DeltaWing coupe in recent weeks. As the team heads to the Mobil 1 SportsCar Grand Prix Presented by Hawk Performance at Canadian Tire Motorsports Park – a fast, flowing track that allows the innovative sports car prototype to maximize its straight line speed – team manager Tim Keene and race engineer Alan Mugglestone highlight these updates.

The main areas of development have been the gearbox and the differential. As the coupe increases in performance, the balance between the car’s light weight and the need for stronger components has been a very delicate proposition. The team incrementally added to the strength and layout of the gearbox, with wider gears, stronger bevel gears and now a stronger mounting. The team works with suppliers for these components but the bulk of the DeltaWing coupe’s parts are designed and built by the team.

The team has also successfully tested a differential, which raced for the first time at Watkins Glen. The DeltaWing was originally designed with a very complicated and experimental electronic differential that would not only help the car drive, but turn under braking. For a number of reasons, the concept was abandoned in favor of an “open” differential. The new differential performed well at tests last month and helped put the DeltaWing coupe in the top seven for much of the first two hours at The Glen, while the car’s fuel efficiency put the car in the lead during pit stops before a problem with the gearbox mounting ended the day.

Keene and Mugglestone are optimistic heading into the weekend at CTMP, where the team saw competitive times last season.

“The DeltaWing coupe is more suited to a track that allows constant momentum,” said Keene. “The Daytona Prototypes have so much more horsepower and torque off of slow corners than we do, so the more we can keep the smaller engine revved up the better it is for us – and these next two tracks lend themselves to that. Given the weight of the car, our aero is very efficient for high speed because most of our downforce comes from the bottom of the car rather than large wings or dive planes. It’s a much more efficient way to create downforce with less drag, which is the car’s basic concept.”

“The DeltaWing concept doesn’t produce a huge amount of downforce compared to a DP or a P2,” Mugglestone added. “It was designed to be a very low drag, fuel efficient car. So when you lose a small amount of downforce as we did when we went from the roadster to the coupe, it’s a much larger percentage. The switch to Continental tires – with a bit less width on the rear tire – enabled us to modify the floor and get some of that downforce back.

“With the limited slip differential we’re running now, an unloaded wheel will transfer torque to the loaded wheel. So we picked up traction in the corners, which puts the gearbox under the same stress but for longer periods of time. We’ve backed off the horsepower to the point where we know the engine is not breaking the gearbox, because we’re below the recommended torque. We’re going faster because we have more grip, both from the tires and from the fact that we now have two rear wheels driving forward. The stronger gearbox should be able to handle that.”

As IMSA finds the balance of performance between the three disparate members of the Prototype class – the Daytona Prototype, the P2 and the DeltaWing coupe – where does the DeltaWing slot in alongside its competitors?

“We’re somewhere between a DP and a P2 in speed,” said Mugglestone. “We don’t have the DP’s power, but we’re lighter weight and we have less drag, so we actually have the acceleration of a DP – but because we didn’t have a differential in the car, we haven’t been able to use it. The P2s are at the opposite end of the scale, with much better cornering ability than either the DP or us but more drag and less horsepower. If you break down the numbers, we’re actually closer to a DP. That’s why CTMP should suit the car, since we can use the straight line speed and keep momentum going.”

As the season continues, the DeltaWing team goal is simple: to maintain the delicate balance between performance, weight and reliability.

“The changes we’ve made will strengthen us for the remainder of the year,” said Keene, “and I expect to see the results of that starting this weekend. We’re looking forward to a good weekend, since fast, flowing tracks like CTMP are favorable to the DeltaWing. So getting to the finish is the priority and if we do that, I expect a good result.”

Force India has sent Renault an early Christmas present by giving tips on how to look after Nico Hulkenberg ahead of his arrival at the team for the 2017 Formula 1 season.

Hulkenberg announced back in October that he would be leaving Force India at the end of the 2016 season, joining Renault for its second year back in F1 as a constructor.

In a tongue-in-cheek post on Force India’s Twitter account, the team gave Renault some advice on how to look after Hulkenberg.

“He answers the name of ‘Nico’, but ‘Hulk’ will do in public,” it reads.

“He has been a beloved member of our family for longer than we can remember, but it is time for him to go and find his own feet.

“Nico is friendly and of good nature, but there are just a few, simple rules to follow to take care of him:

  • Do not feed him after midnight.
  • Do not get him wet. Actually, just kidding. He’s pretty good in the wet.
  • Even though the resemblance can be uncanny, do not refer to him as ‘Johnny Bravo’ (if you do, let us know how it goes.

“And most importantly, and we can’t stress this enough…

  • Do NOT make him angry.

“Best of luck for your life together, your friends at Sahara Force India.”

Force India had previously left Hulkenberg’s helmet and race suit under its Christmas tree as a gift for Renault.

Porsche was quick to chip in on the claim that you shouldn’t feed Hulkenberg after midnight, with the German having ran pretty well in the early hours at Le Mans en route to victory in 2015.

The F1 season may be over, but the Twitter fun between the teams will continue through the winter.

Ricciardo: Verstappen’s arrival at Red Bull pushed me on

Daniel Ricciardo says that Max Verstappen’s arrival at Red Bull four races in to the 2016 Formula 1 season helped him to raise his game as a driver.

Verstappen  swapped seats with Daniil Kvyat after the Russian Grand Prix in May, with Ricciardo’s former teammate moving back down to Red Bull’s feeder team, Toro Rosso.

Ricciardo and Verstappen enjoyed a strong 17-race stint as teammates through 2016, each taking one win and enough points to lift Red Bull up to second place in the constructors’ championship.

Reflecting on his season, Ricciardo admitted that he was unsure about how quickly Verstappen would fit in at Red Bull and get up to speed, but that he soon realized the quality of the Dutchman.

“It was a big thing. Especially that first weekend in Spain which was pretty crazy, and not just because he won,” Ricciardo said.

“I suspect the team didn’t know how good Max was and where he was going to fit. His win really gave us good energy and pushed us on to get stronger.

“In Spain everybody was watching, wondering if we’d made a mistake swapping Dany and Max around. I think his win was a relief more than anything. And it definitely pushed us on. Certainly it pushed me on.

“I think I’d been at the right level from the start of the season, which may have caused some of the commotion in the first place because I had a better start than Dany.

“With Max, I felt we were pushing each other from the off. He was closer to me in qualifying and so naturally that provides a spur because you’re looking at each other’s data and finding an extra bit here and there. It makes you better.”

Ricciardo conceded that the amicable relationship with Verstappen could become tense in 2017 should the pair become embroiled in a title fight, but hopes they can retain their mutual respect.

“Well, I’m not naïve. If we’re fighting for wins I’m sure the pressure and tension will rise,” Ricciardo said.

“But hopefully we’ll be able to look each other in the eye and say ‘good job’ afterwards.”

Lewis Hamilton’s year was an odd one. While he was at his brilliant best on a number of occasions, racking up 10 wins – more than any driver not to win the championship in F1 history – there were a handful of costly errors that ultimately cost him the title.

Yes, the reliability woes with the Mercedes power unit through the year hurt his title bid enormously. But that’s racing; bad luck is part and parcel of it, just as Nico Rosberg found out at points in 2014 and 2015.

Instead, Hamilton needs to look at himself to see where he could have done better in 2015. Poor starts in Australia, Bahrain, Italy and Japan were all damaging to his title challenge, as were weekends he was off the boil in Singapore and Baku.

Hamilton proved once again that he has a good balance between his life outside of F1, which he continues to quite clearly enjoy, judging by his Snapchat escapades, and his efforts on-track. He remains the strongest driver in the field. But this year, his old, successful mind-games were unable to knock Rosberg down. Nico had the answer this time around. Let’s see what 2017 brings for the Briton as he searches for a fourth World Championship.

The year of Lewis revolved as much around him off-track as it did on it. Sometimes, his on-track runs ended through a spate of Mercedes mechanical woes, which were as unexpected as they were frustrating after a flawless winter.

Then there were his spats with the press, his Snapchat antics in Suzuka and his otherwise nonchalant approach to some outside-the-car commitments. From the outside, it seemed Hamilton was less engaged this year until he needed to be, then made peace with the fact he’d done all he could do as the year went on.

The year was defined, performance-wise, by his starts – and how poor some of them were. A number of wins were lost as a result. Even so, he still beat Rosberg 10-9 in wins and 12-8 in poles. The area he beat Rosberg in a category he wouldn’t want is DNFs – that crushing engine failure in Malaysia joined with the pair’s clash in Spain.

Hamilton was his usual peerless self at times though, and his rally to end the season with four straight wins was admirable in the face of a roller coaster year up to that point. His drive at Abu Dhabi was tenacious and smart; he backed Rosberg into the field as his only shot of snatching the title. He remains F1’s most fascinating character and out-and-out fastest driver, if not its current World Champion.

As part of MotorSportsTalk’s review of the 2016 Formula 1 season, Luke Smith and Tony DiZinno look back on each driver’s year, starting today with World Champion Nico Rosberg.

Nico Rosberg

Team: Mercedes AMG Petronas
Car No.: 6
Races: 21
Wins: 9
Podiums (excluding wins): 6
Pole Positions: 8
Fastest Laps: 6
Points: 385
Laps Led: 489
Championship Position: 1st

Assuming that he doesn’t backtrack on his decision to retire from racing at any point in the future, 2016 will be remembered as the strongest year of Nico Rosberg’s motorsport career. Twice burned by championship defeats to Lewis Hamilton, the German bit back in 2016 with a new approach that yielded the ultimate reward.

Sure, his “one race at a time” rhetoric was boring; we like our champions to have some fire in their bellies. However, it worked wonders. Rosberg was no longer taking baggage and stress from race to race as he was through 2014 and 2015. Each race was a clean slate.

There were low moments, such as the clash with Hamilton on-track in Austria, but Rosberg recovered from his mid-season wobble nicely. Four second places is hardly the way to sign off a championship-winning season, but Rosberg cared little – he’d got the job done.

The greatest shame for 2017 is that we won’t get the chance to see if Rosberg can build on this breakthrough year and beat Hamilton again. Instead, he’s ‘one and done’; that’s it.

Tony DiZinno (@tonydizinno)

In the last year of the current regulations, Nico Rosberg always needed to win this year’s World Championship if he was to ensure he ever won one in his career. Rare do you think of him as being 31 years old, in the sport 11 seasons, because he still has a fresh face look – albeit not as young as his initial “baby face” days with Williams, and the birth of a potential mullet to match his World Champion father Keke.

Alas, Rosberg had whatever momentum carried over from winning the last three races of last season, and opened the year with four wins on the trot. The 2016 version of Rosberg did not crack despite the contact with Lewis Hamilton in Spain, nor really, through Hamilton’s midsummer run of six wins in seven races. Only in Austria did it ever look like Rosberg was really on the back foot.

His starts helped propel him all season and that crucial post-summer run of form with wins in Spa, Monza, Singapore and Suzuka was what shifted the momentum back in his corner. He trailed Hamilton by as many as 19 points but by Suzuka was up 33. He brought it home as needed to the finish, and is a deserving World Champ.
