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.

Laguna Seca Shoot-Out: McLaren P1 vs. 2015 Porsche 918 Spyder [VIDEO]

Two 900 hp plug-in hybrids, the McLaren P1 versus the Porsche 918 Spyder.

Both of these cars have carbon fiber tubs and body panels. Both have small displacement, high revving V-8s packed between their passenger compartments and rear axles. Both use twin-clutch transmissions, carbon ceramic brakes, and active aerodynamics. Both have roughly 900 hp.

With the help of pro racing driver Randy Pobst, Motor Trend find out which one is fastest around Mazda Raceway Laguna Seca!

Chris Harris – McLaren P1 Hybrid [VIDEO]

Chris Harris takes the McLaren P1 hybrid hypercar for a drive around the UK in typical wet British weather.

The car is obviously a gorgeous piece of automotive engineering but watching this video you could be forgiven for forgetting the P1 is a hybrid. Unfortunately no mention is made of the electric powertrain until the last minute of the film when Harris hits E-mode for a short demo.

Better late than never, as the saying goes!

Nissan LEAF Battery Reliability Outperforms Cynics [VIDEO]

Robert Llewellyn, from Red Dwarf & Fully Charged fame, debunks motoring journalists who when the Nissan Leaf was launched questioned it's battery reliability.

Of the 30,000 sold across Europe just 0.01% of batteries have been replaced since 2010. That makes the Nissan Leaf more reliable than a petrol or diesel engined car, according to industry averages.

Heat-gathering tire charges electric cars on the move [VIDEO]

At the Geneva auto show, Goodyear shows off an intriguing concept tire that would feed an electric car's batteries while rolling down the road.

The concept – named "BHO3" – offers the possibility of charging the batteries of electric cars by transforming the heat generated by the rolling tire into electrical energy.

This tire generates electricity through the action of thermo / piezoelectric materials in the tire that capture and transform the energy created by heat when it flexes as it rolls during normal driving conditions. The materials used would optimize the tire's electricity generation capabilities as well as its rolling resistance.

As demand for electric cars grows, this technology has the potential to significantly contribute to the solution of future mobility challenges. This visionary tire technology could eliminate the vehicle-range anxiety motorists may have with electric cars.

Nissan GT-R LMP1 NISMO unveiled [VIDEO]

This is the Nissan NISMO entry to the 2015 Le Mans 24 Hour race, the GT-R LM NISMO.

The GT-R LM NISMO is a front-engined, front wheel drive car that is powered by a V6 3-litre twin turbo petrol engine and a kinetic energy recovery system- It is the ultimate GT-R.

Some info on the Nissan LMP1:

  • 3.0ltr Twin Turbo charged V6 based on GTR engine.
  • Front wheel drive which is driven by GTR engine.
  • 8 megajoule energy storage.
  • Narrower rear tires than the front.
  • Front torque vectoring system which controls the front wheel drive system controlling how much power can go to each wheel.

    Nissan has yet to announce how retrieved energy is stored, but it is understood that it is a flywheel system.

    Tesla Model X Caught Testing [VIDEO]

    Youtuber Juan del Real shot this video of a Tesla Model X being tested at the former naval air station in Alameda California about 30 miles north of Tesla's factory in Fremont.

    Based on the size of the Model S in the background, Jalopnik think the camouflaged prototype looks too small to be a Model X and believe this may in fact be the first sighting of a Model 3.

    Toyota to Trial New SiC Power Semiconductor Technology [VIDEO]

    Using a "Camry" hybrid prototype and a fuel cell bus, Toyota Motor Corporation will bring a brand new technology to the streets of Japan for testing this year. The tests will evaluate the performance of silicon carbide (SiC) power semiconductors, which could lead to significant efficiency improvements in hybrids and other vehicles with electric powertrains.

    Technology

    Power semiconductors are found in power control units (PCUs), which are used to control motor drive power in hybrids and other vehicles with electric powertrains. PCUs play a crucial role in the use of electricity, supplying battery power to the motors during operation and recharging the battery using energy recovered during deceleration.

    At present, power semiconductors account for approximately 20 percent of a vehicle's total electrical losses, meaning that raising the efficiency of the power semiconductors is a promising way to increase powertrain efficiency.

    By comparison with existing silicon power semiconductors, the newly developed high quality silicon carbide (SiC) power semiconductors create less resistance when electricity flows through them. The technologies behind these SiC power semiconductors were developed jointly by Toyota, Denso Corporation, and Toyota Central R&D Labs., Inc. as part of the results of a broader R&D project* in Japan.

    Test vehicles and period

    In the Camry hybrid prototype, Toyota is installing SiC power semiconductors (transistors and diodes) in the PCU's internal voltage step-up converter and the inverter that controls the motor. Data gathered will include PCU voltage and current as well as driving speeds, driving patterns, and conditions such as outside temperature. By comparing this information with data from silicon semiconductors currently in use, Toyota will assess the improvement to efficiency achieved by the new SiC power semiconductors. Road testing of the Camry prototype will begin (primarily in Toyota City) in early February 2015, and will continue for about one year.

    Similarly, on January 9, 2015, Toyota began collecting operating data from a fuel cell bus currently in regular commercial operation in Toyota City. The bus features SiC diodes in the fuel cell voltage step-up converter, which is used to control the voltage of electricity from the fuel cell stack.

    Data from testing will be reflected in development, with the goal of putting the new SiC power semiconductors into practical use as soon as possible.
