What to look forward to in 2015 if it's got wheels and they keep score



January's bleak, isn't it? Once you've watched those season review DVDs you got for Christmas, the first session of competitive motorsport seems so long away. Apart from the Dakar, of course. It's just kicked off in Argentina, and the action shots from yesterday's first stage are enough to take the chill off the start of the year. It looks gruelling and very, very hot. But what else should we be excited about in 2015?

Nissan to join Toyota, Audi and Porsche this year

Endurance racing
For me, the big news this year is that Nissan will join Audi, Porsche and Toyota in LMP1.

The GT-R LM NISMO will be unveiled in February (we think), but the rumours currently circulating allege that Ben Bowlby's creation - he of DeltaWing fame - will be equally unconventional. We're potentially talking a front-engined chassis, with a turbocharged V6 (expect Cosworth involvement) driving the front wheels. A Flybrid flywheel hybrid system will power the back axle.

Just like the DeltaWing and the ZEOD, expect the GT-R LM NISMO to challenge convention. In fact, it could flip the current, accepted approach to building a prototype on its head.

Counting down the days...

More weight on the front for more grip (something LMP1 cars struggle with even now they use front wings), with enough downforce generated at the rear from the underfloor to allow for the rear wing to be junked, giving a massive reduction in drag. A narrow rear track, with narrower rubber at the back than the front, should also help here.

So, slippery down the straights, decent grip and balance through the quick stuff, and the hybrid powertrain's efficiency magnified thanks to the lack of drag. Should the other three be worried?

Very possibly. The ZEOD Garage 56 project was a bit of a disappointment, but it was a public test and development exercise for some of the technology that'll be in the GT-R LM.

Besides, reliability is something that comes through racing, as Porsche found out last year. But with three 919 Hybrids, three R18 E-Tron quattros and two TS040 Hybrids confirmed for Le Mans, Nissan's three GT-R LMs are going to be up against it, innovative approach or not.

How close can the others get this season?

F1
Last season F1 proved interesting - or more so than recent years. Partly because of the introduction of new powertrains causing a certain level of unpredictability. Reliability improved massively over the season, but with an engine freeze on the cards for this year at the end of last, it seemed like F1 had the potential to return to the V8 borefest of years gone by.

Potentially not so for 2015. A loophole in the regs that the FIA hasn't managed to close means the sport's governing body has now confirmed teams will be able to tweak their power units during this season.

It should please Renault and Ferrari, although they're playing catch-up to Merc anyway. And with the Silver Arrows sitting on a year's worth of data from the factory and customer teams, there are surely myriad changes it'll try and make too.

Ferrari will hope for improvement in 2015

It'll be a case of diminishing returns just like it always is, but we're only one year into this era of Formula 1. Therefore don't expect Renault and Ferrari to close the gap all that much, as they both try and implement improvements Mercedes was already running on its 2014 spec motors.

Honda will be up against it though, as a new manufacturer the 2015 rules don't allow it any development freedom. Let's hope it doesn't detrimentally affect the McLarens too much.

It'll be the first time in years we've seen in-season changes. With the power units split into 66 arbitrary tokens, the FIA has confirmed 32 tokens can be modified this year - around 48 per cent of the engine.

That's quite a lot. The likes of Ferrari and Lotus are going to need more than a few components to catch Mercedes and Williams, but this big change should at least add another element for the fans, and yet another dead horse for the analysis shows to flog come the end of the season.

Business as usual for 2015?

WRC
Sebastien Ogier is more than likely going to have it harder this year. As defending champion, sticking with VW, he'll likely still be the one to beat - and now that the running order for the first two legs of a rally follows championship position, he'll have his work cut out to sweep the road further still.

Obviously we're making a massive assumption here, that he and the Polo will still be the class of the field based on last season's form, but would you bet against him and VW? Really?

More interestingly, we'll see more diversity in in 2015, so just when your ears have had enough of being buzzed by four-pot turbo WRC and R5 cars, your ossicles could be excited by the shriek of a 911 GT3 or the bark of an Exige. Under new R-GT rules for this season, there'll be an R-GT Cup for competitors. When you're actually fighting for silverware it makes sinking all that cash into a project just that little bit easier. Sort of.

We've already seen Tuthill's 997 GT3, and a Lotus Exige S ran to R-GT rules back in 2012, but with the FIA acknowledging the desire of the market to rally GT cars, could we see a Nissan GT-R (four-wheel drive's got to help) or even an Aston V8 Vantage in stage - after all, Aston has form there (see the batch of images from 300bhp/ton in the thread).

Turkington will be out to defend his BTCC title

BTCC
On the face of things it'll be status quo in the BTCC for 2015. However, a few significant tweaks have been made. All engines running in this year's championship have been re-tested and boost levels set accordingly to further equalise performance and close up any gaps.

There'll be more success ballast for race wins, too (exact increases from the current 45kg max TBC), to try and keep things tight and take the title right down to the wire just like last year.

When we say status quo, we mean you'll need a feeler gauge to determine the gap between cars. Expect that proverbial Swan Vesta paper you'll just be able to get between hatchbacks to get crushed and crumpled on a number of occasions throughout the season.

WTCC
Like the British championship, not much is new for the BTCC in 2015. Citroen will still be the team to beat, especially now it's expanding its entry to five cars.

This season will be the last for V8s in DTM
This season will be the last for V8s in DTM
The factory C-Elysees will be driven by the same three, while Sebastien Loeb Racing will field the other two. Loeb himself won't drive under his own team's banner, as we understand it.

DTM
With the Deutsche Tourenwagen Meisterschaft heading for downsized 2.0-litre turbo engines, following Japanese Super GT that made the switch last season, 2015 will be a year in limbo for German touring cars.

Well, that's one way to look at it. The other is that it's the last year of the screaming flat crank V8s and that we should try and get as much exposure as possible.

British F3
In recent years British F3 has had its peaks and troughs, but there genuinely is nothing to look forward to this year: the championship will not exist in 2015.

No British F3 for 2015; shame
No British F3 for 2015; shame
That's not to say it won't be rekindled in years to come, but it's sad news. Look at the number of world champions that have cut their teeth in the series and you'll understand its importance.

A cocktail of stale rules, poor promotion, cost and competition from elsewhere has squeezed British F3's popularity, marginalising the championship to the point where it's now sharing a bed with the Dodo.

Let's hope this time next year, after a year without and some time to reflect, someone with some money and nous resurrects British F3, turning it back into a fertile ground for developing drivers, what it traditionally has been and still should be.

Stop falling for the marketing nonsense! If it's a front engined car, I can't believe Nissan are in it to win.

More weight on the front for more grip? Are they going to re-write the laws of physics, too?

Aside from the prototypes, I'm looking forward to seeing Bentley back at Le Mans. The car looks epic - so wrong, yet so right. Back to the days of "the world's fastest lorries", or whatever it was Bugatti derided them as.

I don't think Bentley have any Le Mans plans at the moment. There have been hints about a possible GTE project, but definitely nothing concrete - and certainly not this year. The GT3 Continental isn't eligible for Le Mans.

Someone's been listening to Midweek Motorsport, evidently...

What's next, PH, cryptic comments about llamas?

More weight at an axle = more grip.

More weight transfer at an axle != more grip.

Nope.. think the laws of physics are fine as they are. With the same "trickery" of chassis balancing used on the Deltawing, there's no reason why FWD won't work. smile

Except you lose a shed load of front downforce because you have an engine getting in the way of your fancy front wing.

When we move the weight distribution around the balance moves to understeer with a forward weight bias and oversteer with a rearward bias. This has tended to work in all classes of racing I've been involved with. Obviously things change in the different phases of the turn, but as a basic rule of thumb that seems to work.

That will be true when you aren't adjusting the chassis to suit, but as stated in the article Nissan will be using tyre width and roll stiffness biases to work with a heavier front end. Similar to how the Deltawing worked - despite having 2CV tyres - but in reverse.

I've yet to see the car unveiled, but I don't see why the engine would be much more intrusive than the current driver compartment wrt front aero. There's no reason why there wouldn't be enough space to divert flow off the wing out the top / sides like they do currently. I should also imagine they could position their diffuser entry to regain any front downforce lost, too.

I'm very much looking forward to seeing how their package works. smile

(As a side note, I should imagine Nissan will have evaluated the predicted performance of this FWD concept vs. conventional RWD and found it to be advantageous enough to pursue, not merely as a gimmick!)
