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.”

Two-time Indianapolis 500 winner Juan Pablo Montoya added another trophy to his cabinet on Saturday by claiming a shock victory in the Race of Champions.

The event at the Marlins Park in Miami pitted some of motorsport’s biggest names up against each other in a multi-discipline challenge, with the Race of Champions’ traditional crossover circuit style being used.

Ahead of the battle for national honors on Sunday, the 17 drivers on the entry list in Miami faced off for the individual title.

Defending champion and four-time F1 world champion Sebastian Vettel suffered a shock exit in the group stage after defeats to Helio Castroneves and Travis Pastrana. The German won only one tie against 2016 Indy 500 winner Alexander Rossi, who in turn had qualified following a shoot-out against GRC’s Scott Speed.

In the bottom half of the draw, IndyCar stars James Hinchcliffe, Ryan Hunter-Reay and Tony Kanaan were eliminated in the group stages, while veteran British F1 racers David Coulthard and Jenson Button made it through. The pair were joined by nine-time Le Mans winner Tom Kristensen and NASCAR’s Kyle Busch; the latter’s brother, Kurt, was knocked out at the first hurdle.

Pastrana and Castroneves both fell in the quarter-finals, losing to Felipe Massa and Montoya respectively. Massa advanced through the draw despite a frightening incident in the group stage involving fellow F1 driver Pascal Wehrlein, who flipped his car after crossing the finish line.

Kristensen edged out Button 2-1 in their best-of-three bout to reach the semi-finals, setting up a tie against Coulthard after he eased past Kyle Busch 2-0.

Massa and Montoya’s semi-final went down to a tie-breaker, with the former receiving a time penalty to hitting the wall and gaining an advantage. As a result, Montoya progressed into the final, winning the tie 2-1. Losing 2015 finalist Kristensen followed Montoya through, beating Coulthard 2-0.

Montoya won the first heat of the final in the rallycross car, edging Kristensen out by less than a car length before jumping into a KTM X-Bow for the second match-up. Despite almost jumping the start, Montoya managed to wrestle his car through the two laps before edging out Kristensen by just 0.08 seconds, securing a shock rookie victory in the process.

“Honestly I had a blast,” Montoya said. “It’s pretty amazing. I told my wife, I’ve got to make it through the first round. It just worked out.”

Montoya will race in the ROC Nations Cup on Sunday, teaming up with recent IndyCar racer Gabby Chaves for Team Colombia.

Report: Manor making progress in talks to make start of F1 season

Manor Racing has made progress in talks with a possible investor as it bids to make the grid for the start of the 2017 Formula 1 season, according to a report from BBC Sport.

Manor confirmed at the beginning of the month that it had entered administration for the second time in three years amid ongoing financial difficulties.

The backmarker team finished 11th in last year’s constructors’ championship, dropping behind Sauber at the penultimate round and missing out on a sizeable amount of prize money as a result.

With a little over one month to go until the start of pre-season testing, Manor faces a race against time to keep racing, but the latest report from BBC Sport suggests that a breakthrough has been made.

Andrew Benson writes that the future of the team is dependent on the promised investment arriving in the next week, noting that “prospects have improved considerably over the last few days”.

Manor had previously been in talks with Mexican-American businessman Tavo Hellmund over a buyout, as well as a Chinese consortium. The report from BBC Sport also names Indonesian businessman Ricardo Galael, the father of GP2 racer Sean Galael, as a possible suitor for the team.

NBC Sports learned last week that the team is pushing to race with a modified version of its 2016 car – likely to be named the MRT05B – should it make the grid in 2017.

If Manor fails to find a buyer, the F1 grid will drop back down to 10 teams for the 2017 season, returning to its pre-2016 level prior to the arrival of Haas.

NBC Sports has approached Manor’s administrators, FRP Advisory, for comment.

Jacques Villeneuve: F1 is ‘supposed to be too expensive, too crazy’

1997 Formula 1 world champion Jacques Villeneuve feels that he cannot relate to the series in its current form, saying that it is supposed to be “too expensive” and “too crazy”.

Villeneuve raced in F1 between 1996 and 2006, and remains a keen observer as part of his role as a pundit on Italian television.

F1 has striven to enforce greater cost control and road relevance in recent years, but Villeneuve believes that this is the wrong direction, saying officials should instead focus on making the series spectacular.

“That’s when I start to feel old because I don’t relate to the technology of modern Formula 1,” Villeneuve said.

“Because to my mind, Formula 1 has always been about extremes. Pushing the boundaries and human boundaries.

“It’s supposed to be too fast, it’s supposed to be too expensive, it’s supposed to be crazy. And that’s not what we have.

“You see drivers get out of the car and they didn’t even break a sweat because they have too massage their car the whole race and drive within eight seconds of what they’ve done in qualifying. It’s wrong.”

Villeneuve also believes that those in charge of F1 should not listen to fans’ opinions, citing the introduction of DRS in 2011 as being a negative result of doing so.

“The fans kept complaining that ‘oh, there’s not enough overtaking’, ‘oh, there’s not enough of this or that’,” Villeneuve said.

“By listening to that, what did F1 do? Let’s put DRS. Because that way we’ll have hundreds of overtakes in a race. But name me one overtake that you remember since DRS – you don’t. Because you don’t see the driver working it.

“Look at a motorbike race, sometimes they take a rider 10 laps to overtake another rider, but in these 10 laps you see the work that goes with it, and what that overtake happens, wow.

“But now you don’t. Next straight line, press a button, that’s it. All of these rule changes to try and create a better show actually create a worse show.

“Then the technology, take the engine, amazing beautiful technology – for the engineers. It shouldn’t be in F1. It doesn’t bring anything. It takes away from F1.

“It has nothing to do there. It’s crazy engineering. I wouldn’t want it on my road car.”

WRC’s Paddon calls for lessons to be learned from Monte Carlo spectator death

FIA World Rally Championship racer Hayden Paddon has called for lessons to be learned following the death of a spectator on the opening stage of the Monte Carlo Rally on Thursday night.

A spectator was killed after being struck by Paddon’s car when the New Zealander hit black ice and careered into a roadside bank.

Hyundai driver Paddon was withdrawn from the remainder of the rally out of respect, and has now issued a statement regarding the incident.

Here is the statement in full:

Hi everyone,

Upon reflection, I wanted to issue a small statement about yesterday’s events.

Firstly, our thoughts are with the family and friends of the spectator involved. No matter the circumstances, this is never something we want to see.

Secondly, John [Kennard, co-driver] and I are humbled by all the messages of support at this time. Obviously, my thoughts are with the family and that is my only concern at the moment. Not being able to return home to New Zealand does make it a little tougher but it is important we stay strong.

I do want to take this chance to ask people not to speculate. Irrespective of how and why the accident happened, finger pointing will not change anything. The most important thing is that we learn from this and I am committed to work with the FIA and rally organizers relentlessly to ensure this does not happen again.

I will take this chance to ask spectators at rallies to please be considerate of where you stand and to respect the instructions of the marshals. We all want to enjoy a good show and go home to the family afterwards.

I also ask each and every rally fan at the events, if you see someone in a dangerous position to request they move for everyone’s best interest. As a community, we can collectively work together to prevent this from happening again.

Lastly, I please ask the respect from the media in these times, especially for the family and friends of the spectator. I will not issue any further statements or conduct interviews at this stage. We made the decision not to continue this weekend out of respect, but will be back in Sweden where we will pay tribute.

Thank you again for everyone’s support and for the support of the team – it really does mean a lot.”

The Monte Carlo Rally finishes on Saturday.
