What You Need to Know About LMP1 Hybrids Leading up to Le Mans [VIDEO]

The hybridised World Endurance Championship has introduced a new version of cut and thrust racing that is very entertaining to watch but I'm not sure either Jalopnik nor the (with respect) race commentators fully understand how the very different hybrid systems interact on the track.

The video sequence features a race for position between the Audi R18 E-Tron Quattro and the Porsche 919 Hybrid. While these cars are both in the same LMP1 hybrid class, the rules allow for a large amount of technical freedom (especially when compared to many other 'control formula' International championships).

The 2015 Audi R18 features a 558 HP (410 kW) 4.0-liter Turbo Diesel V6 combustion engine driving the rear wheels with a 272 HP (200 kW) electric motor driving the front wheels. The R18 is in the 4 Megajule class with a flywheel energy storage system can store 700 kilojoules.

The Porsche 919 Hybrid features a 500 Hp (370 kW) 2.0-liter Turbo Petrol V4 combustion engine driving the rear wheels with a 400 HP (300 kW) electric motor driving the front wheels. The 919 is in the 8 Megajule class with an A123 Lithium-ion battery energy storage system and also has thermodynamic energy recuperation using the energy from exhaust gases from the turbo charger.

The energy class regulations refer to the amount of regenerated energy that can be used each lap, for example 8 megajoules equals 2.2 kWh that can be deployed around the race track (3.6 megajoules is equivalent to 1 kilowatt hour (kWh).

Like in Formula One, the energy recuperation is pre-programmed and not directly controlled by the drivers, what might be confusing is that unlike in F1 where output from the KERS systems is driver controlled via a steering wheel mounted 'boost' button, in the WEC the KERS output is also pre-programmed. In fact KERS 'boost' buttons are banned in the WEC.

The FIA specify hybrid ‘braking zones’ where teams can program energy recovery. The hybrid output can be used anywhere around the track and is calculated by race engineers pre-race to maximise the use of this energy for fastest laps times with minimal fuel burn. As a result, what we're seeing in the video above where the Porsche 919 is said to be "running out of hybrid power" is in fact the same pre-programmed energy duty cycle used by the 919 on every laps of the race. This becomes very clear watching extended in-car race footage (the FIA WEC on-line package offers full race in-car access to all works LMP1 cars). What we see as the Porsche massively out accelerates the Audi at the top of Eau Rouge is a combination of the 919 having a 60 kW advantage over the Audi and where the Porsche is pre-programmed to apply it's 4Mj of additional hybrid power. Again, the 919 drives this duty cycle every lap.

There are other very interesting differences at play such as braking performance. Where the Audi (flywheel) and Toyota (super capacitor) systems can recover a 'full charge' during high speed braking, while the Porsche (li-ion battery) has a noticeable extended high speed braking profile, e.g the 919 starts braking a longer distance before the corner, and is belived to take several braking zones to recover a 'full charge'. This is due to the asymmetric charge and discharge curves of lithium ion batteries and is partially compensated for by the thermodynamic turbo generator which makes the Porsche 919 Hybrid the only car in the field that recuperates energy not only when it brakes but also when it accelerates.

Motorsport is a technical sport and this is exactly what racing is meant to be about, advancing automotive technology.

Infiniti’s Vision GT Hybrid concept [VIDEO]

Looking virtually identical to the digital model created for Gran Turismo 6, the real world Vision GT concept provides a glimpse at what a "high performance Infiniti could look like in the future.”

While the company didn't have much to say about the car, it has a naturally aspirated 4.5-litre V8 petrol-electric hybrid system powering the rear wheels and features an aggressive front fascia with a prominent grille that is flanked by slender headlights and sporty air intakes. Moving further back, there's sporty side skirts, carbon fiber trim and massive alloy wheels.

According to the game maker’s, the Infiniti Concept Vision Gran Turismo’s electric motor delivers “overwhelming torque” in low-speed situations while at higher speeds, the V8 engine teams “immense power”

Peugeot 308 R Hybrid 500 hp AWD hot hatch [VIDEO]

Feast your eyes on the ultimate 308. PEUGEOT has unveiled a stunning new version of the compact family hatchback – with a combined 500 bhp and four-wheel drive.

Badged the PEUGEOT 308 R HYbrid, it has been developed by PEUGEOT Sport, the brand’s famous in-house engineering and racing division, which last year unveiled the critically acclaimed RCZ R. The car’s plug-in petrol hybrid powertrain results in a car capable of hitting 62mph (100km/h) in 4.0 seconds, yet still has astonishingly low CO2 emissions of 70g/km.

At the heart of the PEUGEOT 308 R HYbrid is a plug-in powertrain with four-wheel drive that develops 500hp. The unit combines three sources of power, each capable of moving the vehicle independently of the others. They are a four-cylinder 1.6-litre THP 270 S&S petrol engine, plus two electric motors – each with power of 85kW/115hp – mounted one on each axle. The front one is linked to the six-speed gearbox.

The result is a family hatchback which is capable of supercar performance. The PEUGEOT 308 R HYbrid can hit 62mph (100km/h) from a standing start in only 4.0 seconds, with top speed electronically limited to 155mph. In spite of such astonishing performance, CO2 emissions are just 70g/km.

“If we were able to reach this kind of performance on a C-segment, it is all down to our passion for a challenge and our desire for excellence. PEUGEOT 308 R HYbrid is part of a very select club of cars reaching 0-62mph in four seconds” says Jean-Philippe Delaire, PEUGEOT Sport Head of Development, 308 R HYbrid powertrain.

PEUGEOT Sport has been involved in every stage of development of the 308 R HYbrid, using its technical expertise and successful racing record to define the specifications of each component. For impeccable dynamic handling, the car’s weight has been optimised and placed as low as possible. The lithium-ion 3kWh battery has an excellent ratio between power and size, and is housed under the rear seats in place of the fuel tank. In turn, the 50-litre tank has been placed in the boot above the rear electric motor and two transformers.

The PEUGEOT Sport engineers have equipped the car with four driving modes:

  • Hot Lap mode is the most powerful, harnessing the full potential from the three power sources to reach a total of 500hp and maximum torque of 730Nm.
  • Track mode delivers 400hp and 530Nm, mainly from the petrol engine and the rear electric motor. The front electric motor serves as an additional booster when accelerating.
  • Road mode is specially designed for road use with power of 300hp and torque of 400Nm. The petrol engine delivers its full potential, while the rear electric motor helps during accelerations. The front electric motor is not used in this mode.
  • ZEV makes priority use of the rear electric motor. The front electric motor comes into play, depending on the pressure applied on the accelerator pedal.

    The all-wheel drive system of the 308 R HYbrid makes for formidable handling, especially when coming out of the corners. The braking system is on a par with the car's performance, with 380mm ventilated discs at the front, gripped by four pistons, and 290mm discs to the rear. However, they are not used every time the brakes are applied, because PEUGEOT Sport has designed the powertrain to decelerate using the electric motors throughout the full speed range, starting at 155mph. Not only does this preserve the discs and pads, but uses regenerative braking to recharge the battery.

    It is one of three recharging strategies. The second uses the front electric motor as a generator, driven by the petrol engine, while the third solution is a rapid recharging terminal restoring the battery to its maximum power in just 45 minutes.

    Nissan Launch X-Trail Hybrid in Japan

    Nissan has introduced the X-Trail Hybrid in Japan, equipped with a 2-liter MR20DD four-cylinder engine and an electric motor.

    Nissan says the hybrid powertrain “delivers a comfortable driving experience with its powerful acceleration and remarkable quietness, which eclipse those of typical 2.5-liter gasoline engines.”

    The 2.0-liter gasoline engine delivers 147PS (145hp) at 6,000 rpm and 207Nm (153lb-ft) of torque from 4,400 rpm, while the RM31 electric motor has a maximum power output of 30 kW (40hp) and a maximum torque of 160Nm (118lb-ft). The hybrid system also includes a high-output lithium-ion battery which is able to charge/discharge quickly.

    In combination with an XTronic CVT, the hybrid powertrain achieves a fuel economy of 20.6 km/l (4.8 l/100 km or 48.5 mpg US) in the JC08 mode and meets Japan’s 2020 fuel economy standards, which means all grades are eligible for tax exemptions.

    Furthermore, the X-Trail Hybrid achieves a 75 percent reduction of NOx (nitrogen oxide) and NMHC (non-methane hydrocarbons) in exhaust emissions over 2005 standards and SU-LEV certification.

    The Nissan X-Trail Hybrid features Intelligent Dual Clutch Control, which is a two-clutch parallel hybrid system that delivers engine and motor energy mechanically to the transmission without having a motor assist or a torque converter, thus favoring responsive starts and acceleration.

    In terms of equipment, the Nissan X-Trail Hybrid gets Forward Emergency Braking as a standard feature, as well as the NissanConnect Navigation System, the latest generation in-car navigation, information and entertainment system with smartphone link application. Nissan is planning to also introduce Forward Emergency Braking as standard on major models in Japan, by the end of autumn 2015. The X-Trail Hybrid is priced from 2,804,760 yen ($23,415).

    Toyota unveil 2016 RAV4 Hybrid [VIDEO]

    Toyota unveiled the new RAV4 Hybrid at the New York International Auto Show. The eighth hybrid in the Toyota lineup, the RAV4 Hybrid offers more power as well as better fuel economy than the conventional RAV4, according to Toyota Group Vice President and General Manager Bill Fay.

    The hybrid system consists of a 4-cylinder, 2.5-liter petrol engine and eCVT transmission along with an All-Wheel-Drive System with Intelligence (AWDi) featuring a rear motor that operates independently from the front motor. This additional electric motor delivers instant torque to the rear wheels only when additional traction is needed, thereby automatically helping prevent wheel spin.

    AWDi adapts to the angle or condition of the road, with no driver input needed. The electronic AWD provides increased safety and stability on slippery surfaces and enables a towing capacity of 1,650 kg (3,634 lbs). Easy and safe towing is ensured thanks to Trailer Sway Control system.

    RAV4 will also offer a new Bird’s Eye View Monitor. This Toyota-first technology utilizes four cameras that are mounted on the front, side mirrors and rear of the vehicle to give the driver a panoramic view of their surroundings. The system offers drivers assistance when parallel parking, and when pulling in and out of parking spaces.

    The Bird’s Eye View Monitor system also has an industry-first feature called Perimeter Scan, that gives drivers a live rotating 360-degree view of what is around the vehicle, helping them see objects that could be in the way.

    BMW doubles i8 production to meet demand

    Although BMW has doubled the production capacity for the plug-in hybrid i8, the order backlog is, according to Production Director Harald Krüger still at 4.5 months.

    "We are really proud to see how this demands develops for a completely new car," Kruger said at the BMW Financial News Conference. Pride partly because of the spectacular E-athletes have been accepted even better than expected in the market, and secondly because the production team at the Leipzig plant has got a handle on the production processes of the vehicle with a high carbon content faster than expected.

    Since launch in summer 2014 a total of 1,741 i8 were delivered. Given the high demand BMW have doubled the production number. Currently 20 cars per day will be built. Nevertheless, demand is still rising.

    Overall, BMW sold 17,793 i models last year including 16,052 i3. Norbert Reithofer acknowledged that BMW are satisfied with the development because of the valuable experience developed through the i-series with Reithofer emphasizing the goal of electrification power trains through all series.

    Audi Launch 2015 R18 E-Tron Quattro WEC

    Audi Motorsport has taken the wraps off the 2015 R18 e-tron quattro scheduled to compete in the FIA World Endurance Championship (WEC).

    The new version has some big shoes to fill taking into account last year's model triumphed at Le Mans, but Audi is confident they can repeat the 2014 success thanks to a more aerodynamic body. It features larger air inlets in the redesigned front wheel arches along with reshaped headlights benefiting from matrix LED and Audi Laserlight technologies. Also new are the front wing, hood and engine cover while the monocoque has been carried over.

    Audi has prepared two body configurations suitable for various tracks of the 2015 WEC calendar and they have also optimized the chassis in collaboration with Michelin. The engineers were responsible for doubling the amount of energy from 2 to 4 megajoules per race lap at Le Mans and during braking the energy recovered is then sent back to the front axle during acceleration.

    The electric motor has been upgraded to 272 HP (200 kW), representing a "significant increase" compared to last year's variant while the encapsulated flywheel energy storage system can now store 700 kilojoules which is 17% more than before.

    The LMP1 prototype tips the scales at just 870 kg (1,918 lbs) and now consumes 2.5% percent less diesel per lap than last year in order to meet the more stringent regulations implemented by FIA. Output of the TDI 4.0-liter V6 engine stands at 558 HP (410 kW) and only five engines will be available during the 2015 WEC season.
