We Really Hope Nissan Puts Its New Racing Engine Into Cars We Can Buy

Nissan Nismo President Shoichi Miyatani hold the powerful, lightweight engine that will power its racecar.

Nissan has revealed the remarkably small, powerful engine that will power its NEOD RC car, which will compete at the 24 Hours of Le Mans race in June.

To illustrate just how unusual this engine is, Nissan showed it off in the arms of Shoichi Miyatani, president of Nismo, Nissan's motorsports and performance division.

The DIG-T R 1.5-liter three-cylinder engine weighs just 88 pounds. It measures 19.68” x 15.74” x 7.78”, small enough to fit in your carry-on bag.

Yet it cranks out 400 horsepower and 280 pound-feet of torque. That's more power per pound than the engines used in this year's Formula 1 Championship, Nissan notes.

The engine won't be doing all the work at Le Mans, however. On each set of laps, the ZEOD RC will run on pure electric power for the first lap, then the DIG-T R will take over. Thus the name, the Zero Emission On Demand Racing Car.

Those who don't care about car racing should still be excited about the new engine. The focus on producing as much power as possible from as little weight as possible is great for developing new technologies that often trickle down to production cars.

In world of high gas prices and federal efficiency standards, a tiny engine that cranks out this much power would be a wonderful thing.

Here's the ZEOD RC car:

Googling the DIG-t R Engine but can't find any info on fuel consumption.
Would love to see this in a production vehicle!

1,000 horsepower Toyota TS040 unveiled
By Sam // March 27, 2014
Toyota TS040
The Toyota TS040 LMP1 has finally been revealed. During an event at the Castellet Circuit in France the Japanese marque showed off the new car and revealed that it has two simple objectives, to win the Le Mans 24 Hours and the World Endurance Championship.
Image


The TMG designed and built chassis is largely conventional and has many cues from the 2012 and 2013 versions of the TS030, but the power train is anything but. Developed by Toyota’s R&D department in Japan it features a more powerful internal combustion engine and an enlarged hybrid system.

A full technical analysis can be found here: Toyota TS040

Rebellion R-ONE takes to the track
By Sam // April 17, 2014
Rebellion R1
The ORECA designed Rebellion R1 LMP has taken to the track at Paul Ricard, barely a year after the start of the project – exactly 363 days after the design of the first piece in CAD.
Image


Two examples of the design will start a full testing program next week, before heading to the 6 Hours of Spa for their first race in the 2014 FIA World Endurance Championship.

Bart Hayden, REBELLION Racing Team Manager : “Today the Rebellion R-One has turned its first laps and we are absolutely delighted by that. After many months of dedicated focus and design effort, the past few weeks have seen an incredible input by the Oreca personnel and members of the REBELLION Racing team. Our mechanics have been in the Oreca factory for the past few weeks without a break and so today’s running of the car is a great reward for all the hard work. Congratulations are due to everyone that has been involved in this project, but particularly to the
design team led by Christophe Guibbal and the REBELLION mechanics led by Garry Richardson.
Our mechanics are now catching the next plane back to England to be at Silverstone for this weekend’s FIA WEC opening race of the season and we will all be coming back to Paul Ricard next week after that race for a full test of the R-One cars.”

Porsche 919
By Andrew Cotton // March 2, 2014
2014 Porsche LMP1
Chassis: - Class: LMP1 Engine:V4 Turbo Fuel: Petrol Transmission: - Brakes: 0 Weight: - Fuel Tank: - Year introduced: 2014

Porsche has introduced its most complex racecar ever to hit the track with the 919 Hybrid. Featuring two energy recovery systems, it is capable of running in the 8MJ category at Le Mans, although a final decision on that has yet to be made.
[Show as slideshow]
zuppork zuppork2 zuppork3 zuppork4 zuppork8 zuporkx7 zuppork4_0 zuppork_0 zupporktop zupporkx00 zupporkx001 zupporkx1 zupporkx2 zupporkx3 zupporkx5 zupporkx6 zupporkx9 zupprokx8

The car features a KERS on the front axle, a single motor as the two run on the Audi in 2013 would count as two separate systems. A Formula 1-style electric motor driven by the exhaust gasses is housed at the rear, though this is said to be incapable of acting as a motor. Energy from both is stored in a battery provided exclusively to Porsche by A123. The car is powered by a 2-litre V4 engine, which has been extensively re-designed since it first hit the track in June, 2013.
However, from the moment the car hit the track, a vibration issue with the V4 engine caused the interlinked suspension to break. A major redesign of the engine was commissioned early on, instigated by the Technical Director Alex Hitzinger. That engine, featuring a new crankshaft, was installed for the test in Portimao in which Mark Webber completed 600km.
Since then, Porsche has tested in Bahrain, putting race distances on the cars, tyres, hybrid systems, gearboxes and engines. Two 30-hour tests are planned before the Le Mans 24 hours to validate the changes made to the car.
New bodywork has been designed and was first tested at Sebring in mid-March.
Interestingly, with Audi’s confirmation that it will run with only one hybrid system in 2014, only Porsche and Toyota will be in a position to go for the full 8MJ release rate at Le Mans. However, Porsche says that it will wait until endurance testing is complete before it decides on which category in which it will run.
Fuel Flow meter
Porsche has been outspoken in its criticism of the Gill Sensors Ultrasonic Fuel Flow meter with which the 919 will run this year. Gasoline cars must run with two sensors, diesel with three, but Porsche says that there is ‘no robust solution’ to the measuring process and doubts that there will be this season.
‘It hasn’t held us back because we did not make our development dependent on it, but there is still no robust solution in place,’ said Hitzinger. ‘The FIA is still very hopeful that the latest spec will work and will be reliable, but that is not proven yet. We optimise how they are mounted to give them the easiest possible life, but right now we don’t know if it is all going to be robust. We should know at the end of March.’
Technical analysis by Sam Collins

PRE LAUNCH TESTING: WEISSACH, MONZA, CASTELLET HTTT
Whilst few exact details have been released the images and information that has come out is fascinating in itself.
Overall the aerodynamic package of the car seems largely conventional, but it is certain that the final bodywork has yet to be seen, but there are some clear pointers.
Porsche 919
The car features a ‘legality bump’ in the roof (above) to allow it to meet the new minimum height regulations, something not seen on the rival Audi R18 or Adess/Lotus (also built to the 2014 chassis rules).

The cars power unit was at first thought to be a derivative of the never raced early 2014 spec Volkswagen F1 inline four engine, but recent information has revealed that this is not the case instead it is a turbocharged two litre four cylinder unit.
Videos such as the one above deliberately blur out the engine but there are clear signs that it is a V type engine. A V4 is very unusual format for a racing engine but thought to be a good one.
Porsche 919
The engine is however known to use Formula 1 style exhaust gas recovery and an Audi style front mounted electric motor. Energy storage is a battery pack mounted in the passenger compartment with cells developed by A123 systems, who also supply a number of F1 teams. Not the single exhaust exit, suggesting that the car has a mono turbo layout.
Porsche 919

Porsche has released a couple of interesting videos of the car (below), from these we can glean some further technical information, such as what appears to be Cosworth Electronics equipment in the cockpit.



LAUNCH: GENEVA

Porsche revealed the 919′s technical data at the Geneva Motorshow. The car will use Formula 1 style hybrid technology at Le Mans this year.
Porsche 919
In 2014 the LMP1 category has adopted a Formula 1 style fuel flow limited formula which places the emphasis on energy efficiency rather than on outright performance. Unlike in Formula 1 there is great freedom in power unit configuration in LMP1, the internal combustion engines have no air restrictors or capacity limits which has seen Audi opt for a diesel fuelled V6, Toyota for a normally aspirated V8 while Porsche has opted a two litre turbo charged V4, an unusual configuration.
Porsche 919
The turbocharger is linked to a motor generator unit in the same style as a Formula 1 MGU-H. Though this should really be called a GU-H according to Alex Hitzinger, Porsche LMP1 project leader, as it cannot act in the anti lag role. Whilst the second hybrid system is a front mounted MGU, similar in operation to the MGU-K in Formula 1
Porsche 919
The front suspension layout is clear to see from the above image, rather than use the torsion bar suspension commonplace in LMP1 (and as used on the 9R6 RS Spyder) the 919 uses vertically mounted spring/damper units.
Porsche 919
The energy store is mounted in the cockpit area in the ‘passenger seat’. It is made up of battery cells from A123 systems. The very short V4 engine means that there is a very large carbon fibre bell housing ahead of the transmission (also carbon fibre).
Porsche 919
Packaging is a key issue for the new 919, and dealing with the thermal demands of the power unit is a major area of focus.
Porsche 919
The launch at Pal-expo gave the first proper look at the 919 in its launch spec bodywork. Many elements of the car appeared to be simplified, note the details around the front splitter (below)
Porsche 919
The roof mounted intake has an interesting shape, it is not clear if the large support forms part of the roll over structure. The V-shaped section channels air to a pair of small intakes on the engine cover (below)
Porsche 919
The bump in the roofline (above) is to allow the monocoque to meet the minimum chassis height rules introduced in 2014. This could suggest that the intake support is not structural. The purpose of the small ducts (below) is not clear, it is possible that they could be for transmission or ERS cooling. Note the bulge at the front of the main intake.
Porsche 919

WEC PROLOGUE: CASTELLET HTTT
As expected a very heavily revised Porsche 919 appeared at the WEC Prologue in late March. There appears to have been more than one version of the cars bodywork fitted during a private session ahead of the Prologue, but some major changes are immediately apparent.
Porsche 919
Firstly the nose of the car is totally new, the front opening is much smaller than the launch or early testing specification (below), and the nose is much flatter. The brake ducts have also been removed or included in the main nose duct. A look at the front splitter shows just how different it is.
Porsche 919
These changes probably meant that the car required a new crash test, however as the car had not been homologated in launch specification it may not have been crash tested at all. This does not mean that the car was any less safe, just that the formalities may not have been conducted.
Porsche 919
The roll hoop mounted engine intake has been totally redesigned, replaced by a seemingly smaller more curved duct (above). Interestingly the two intakes further back on the engine cover have been removed altogether.
Porsche 919
What the ACO call “air extractors”, Mike Fuller calls “big honking holes” and we call mandatory wheel arch openings were also slightly modified on the Prologue spec 919. A small gurney has been fitted at the leading edge. New wing mirrors have been fitted also. Compare the original design (below) to the new design (above).
Porsche 919
From the side the number of differences are very clear to see. Not least the three flow conditioning vanes in the area behind the front wheel pod.
Porsche 919
The whole front pod area has been revised, compare the new (above) with the old (below), the front fender shape cuts inward toward the case and the headlamp shape is different. The upper rear portion of the wheel arch is totally different with a new opening just ahead of the wing mirror stalk (above the P1 sticker). Under that position the bodywork follows the shape of the wheel on the new bodywork whilst on the old it is far more angular. The leading edge of the rear wheel pod has also been reshaped and a new duct (probably for rear brake cooling) has been opened up on the flank.
Porsche 919
A different bodywork configuration was trialled on the 919 in the pre Prologue test, it only appears in a few of the official images released by the German marque (below). The three flow conditioners behind the front wheel pod have been replaced with a single plate whilst the other elements remain the same.
http://www.racecar-engineering.com/cars/porsche-919/

Porsche 919
The redesigned rear wheel pods have relocated the brake ducts from the leading edge to the flank of the car.
Porsche 919
Compare the new design (above) to the old spec (below) the size of the brake duct looks to be much smaller.

2014 Porsche 919 hybrid Le Mans prototype

2014 Porsche 911 RSR and 919 Hybrid Le Mans prototype
Porsche used the 2014 Geneva Motor Show this week to show the world its new hybrid Le Mans prototype that will contest the 2014 World Endurance Championship, which includes the 24 Hours of Le Mans. The new Le Mans prototype is the 2014 Porsche 919 Hybrid, and it will compete in the LMP1 category of the WEC.
MUST SEE: Transformers 4 Extended Trailer Released: Video

Porsche is a veteran of endurance racing, having won overall in the prestigious 24 Hours of Le Mans no less than 16 times, but developing a new LMP1 from scratch is no easy task, especially with rivals as strong as Audi and Toyota, which have already had a number of successes with recent prototypes.



Maximum efficiency in energy consumption is the directive of the new WEC regulations for the top LMP1 category--and that is also the direction for the automobile future, according to Porsche. Thus, in developing the new 919 Hybrid, Porsche engineers needed to ensure that every component--from the combustion engine to the energy recovery systems, chassis and running gear, aerodynamics and driver ergonomics--not only performs well but is efficient too.

The combustion engine is a compact V-4 unit that also serves as a load-bearing member in the chassis. It displaces just 2.0 liters but thanks to direct-injection and turbocharging technologies manages to produce close to 500 horsepower.

In addition, the 919 Hybrid has two energy recovery systems. Fundamentally new here is a system that recovers thermal energy from exhaust gases via an electric generator driven by the exhaust gas stream, which is similar to what is being used in the 2014 Formula One season.

The second hybrid system has the functionality familiar from the 918 Spyder supercar. Here, a generator on the front axle utilises braking phases to convert kinetic energy into electric energy. Lithium-ion batteries serve as the energy storage medium. When the driver needs this energy, such as coming out of a corner, an electric motor drives the front axle. This makes the 919 Hybrid an all-wheel drive vehicle temporarily.



Porsche will field two 919 Hybrids in the WEC this season. Driving the number 14 car will be Romain Dumas, Neel Jani and Marc Lieb, while sharing time behind the wheel in the number 20 car will be Timo Bernhard, Brendon Hartley and Mark Webber.

Fellow Volkswagen Group brand Audi, which won this year’s WEC and Le Mans titles, will utilize a TDI diesel engine for the hybrid system in its own 2014 R18 e-tron quattro prototype. Toyota is yet to reveal full details on its 2014 TS040 Hybrid Le Mans prototype but has said it will come with a naturally aspirated V-8.

Joining the 2014 919 Hybrid on Porsche’s stand in Geneva this week was another race car, the 2014-spec 911 RSR. The car is similar to last year’s version and will once again compete in the GTE category of the WEC. Last year the car came first and second in its class in the 24 Hours of Le Mans. It features a naturally aspirated 4.0-liter flat-six engine rated at 470 horsepower. Porsche will field two of the cars in the WEC this year.

The first race of the new season is the 6 Hours of Silverstone, which gets underway in the U.K. on April 20, 2014. In the meantime, catch the rest of our 2014 Geneva Motor Show coverage via our dedicated hub.
