World’s Fastest Electric Motorcycle Has Been Upgraded, Wants to Break Its Own Records
from https://www.autoevolution.com by Cristina Mircea

The fastest electric motorcycle in the world aims to become even faster. Voxan recently unveiled its new and improved Wattman.

Venturi-owned electric motorcycle brand Voxan designed the Wattman with one goal in mind: to set new world speed records. The bike was initially supposed to prove its abilities on the biggest salt flat on Earth, in Bolivia. However, the global health crisis changed everyone’s plans, and the Wattman had to settle for breaking 11 world speed records on the runway at the Chateauroux airfield in France. Nevertheless, it achieved an incredible speed of 408 kph (253.5 mph), with world champion Max Biaggi at the helm.

But that was in the fall of 2020, and Voxan knows there’s always room for improvement. That is why the company announced a new version of the Wattman, which has just kicked off its first ultra-high-speed tests at Space Florida’s Launch and Landing Facility (Kennedy Space Center), one of the longest runways in the world, with a length of 15,000 ft (4.5 km).

Voxan brought some significant upgrades to the new Wattman in terms of weight, stability, and power. This new version weighs under 300 kg (661 lb), allowing it to compete in a new category. Voxan used a new battery design for its latest bike, both mechanical and electric, created in partnership with French manufacturer Saft.

Stability has been improved with the new Wattman, as the modified motorcycle now features an increased wheelbase of 1,957 mm (77 in) from 1,800 mm (70.8 in) with the previous version. The seat height has also been increased from 610 mm (24 in) to 685 mm (26.9 in). Voxan equipped the bike with custom-designed Michelin tires tailored to endure extremely high speeds.

In terms of performance, the new Wattman, which relies on the Mercedes EQ Formula E powertrain, can now deliver powers of 320 kW (429 HP), as opposed to 270 kW (362 HP), for the previous version. As for the torque, it has also increased at 1,360 Nm.

If everything goes according to schedule, the new Wattman will once again attempt to break its own records within the first six months of 2022.

PRESS RELEASE – 15 NOVEMBER 2021

Electric motorcycle brand Voxan, owned by high-performance electric vehicle specialist Venturi, presents the new Wattman. With world champion Max Biaggi at the controls, the brand is setting out to conquer yet more world speed records.

Closer to the stars
The Voxan Wattman was initially due to make its attempts on a Bolivian salt flat in July 2020, but the pandemic made travel impossible, and so it was on the runway at the Châteauroux airfield in France that the team broke 11 world speed records a year ago.

Asphalt proved to be an interesting surface, so the Wattman – modified accordingly – will continue its schedule on another strip. This time, the venue will be the Space Florida’s Launch and Landing Facility at the Kennedy Space Center (Florida, USA), where, from Monday 15 November, the first ultra-high-speed tests will get underway.

Weight – stability – power
The Wattman is now under 300 kilos in weight, allowing it to compete in this category. The weight difference is primarily down to a new Voxan-Saft battery design, which is both mechanical and electric. Saft, the French subsidiary of TotalEnergies, specialises particularly in high-performance, very high-power batteries. The pouch cells used make it possible to increase the batteries’ power by nearly 80 times, compared with around 10 times for standard products on the market. They are assembled in modules, enabling cooling to be managed with a recently patented process, resulting in an ultra-compact construction.

The bike continues to rely on the Mercedes EQ Formula E powertrain, which delivers power of 320 kW (compared with 270 kW for the previous version) and offers torque of 1,360 Nm.

Other notable differences compared with the previous Wattman include the motorcycle’s dimensions: to improve stability and air penetration, the wheelbase has been increased to 1,957 mm (from 1,800 mm previously) and the seat height is now 685 mm (up from 610 mm). In the event of significant crosswinds, the team will now have the flexibility to add a fairing that cuts wind resistance.

As for the tyres, longstanding partner Michelin has worked on designs specifically tailored to this challenge. The front 120/70-17 is a tyre from the MICHELIN Power GP range, which has been modified to tolerate extremely high speeds. For the rear 190/55-17, Michelin has relied on technology that has been proven in MotoGP to develop a tyre with improved grip. The challenge was to channel all of the extraordinary torque delivered by the Wattman’s electric engine, allowing the motorcycle to accelerate as fast as possible without skidding.

Once the new Wattman is ready, further world record attempts will be made – certainly within the first six months of 2022. As they did last year, Max Biaggi and Voxan will seek to beat the clock with two types of motorcycles in two separate categories: “partially streamlined” (traditional sports bike) and “naked” (roadster with no streamlined elements).

Kawasaki Unveils Gas-Electric Hybrid Prototype Motorcycle

Kawasaki Lifts Cover On Its Gas-Electric Hybrid Prototype Bike

A peek behind the curtain/fairings.

We’ve been following Kawasaki’s hybrid motorcycle development since the firm filed patents in July, 2019. By November, 2021, Team Green gave us a peek at its progress with a short video laying out the philosophy behind the project. Then, an April, 2021, patent revealed Kawi’s new 48V hybrid battery design. Now, Kawasaki has pulled back the curtain (and the fairings) on its latest hybrid build while committing to a 2025 gas-electric hybrid production models.

Due to the chassis, front headlight configuration, and exhaust system, the prototype looks like it’s based on the Ninja 400. Kawasaki hasn’t officially confirmed our suspicions, but leveraging the entry-level sportbike aligns with current hybrid technology limitations. In automobiles, it’s easier for manufacturers to pair electric and internal combustion powertrains. In motorcycles, however, space is a much more limited resource. As a result, the firm couples its existing small-capacity parallel twin with a compact electric power unit.

From the beginning, Kawasaki has developed its hybrid project with the idea that riders would utilize the powertrains in different environments. The internal combustion engine suits highway riding, while the electric motor works best in urban environments. On a twisty road, both would work in concert to deliver the best of both worlds. It seems like the small-bore Ninja-based prototype would satisfy those requirements while also providing enough room to accommodate the new apparatus.

Of course, with two powertrains, the transmission will have to play nice with both systems, and Kawi’s automated gearshift smooths that transition. The new feature consists of an automated clutch, servo-powered shifter, and push-buttons for the user to operate. With so many European cities introducing zero emissions zones lately (and only more to come), the hybrid technology may be the perfect happy-medium between holding on to the range and convenience of gas-powered motorcycles while adopting cleaner and more efficient running powertrains.

For some, 2025 may be a long time to wait, but it’s encouraging to see Kawasaki’s project progress at such a rapid rate. Hopefully, we can say the same for the gas-electric hybrid’s acceleration when it hits the market in a few years.

Kawasaki Ninja 400 Based Hybrid Electric Motorcycle Prototype Unveiled

Kawasaki is working on a wide range of fully electric and hybrid motorcycles for the next few years

Kawasaki has made some major announcements recently which reveals the intentions of the Japanese superbike manufacturer for the future. The bikemaker has revealed that by 2035, all its models would run on electrified powertrains- either fully electric or hybrid electric vehicles, in major international markets.

In regard to this idea, the company is planning to launch ten new fully electric and hybrid motorcycles by 2025. The first of them was recently showcased at a presentation meeting in Japan. The prototype revealed is slated to be the first hybrid electric motorcycle from Kawasaki.

However, this isn’t the first motorcycle with an electric powertrain to be unveiled by the Japanese brand. Earlier in 2019, Kawasaki had revealed the electric Ninja 300 Concept, called EV Endeavor. Later the same year, the company filed patents for a hybrid motorcycle, images of which floated on the internet. The recent prototype unveiled is expected to be based on the same patents.

Kawasaki Ninja 400 Hybrid Prototype – Details
Going by the images, Kawasaki appears to have used Ninja 400 as the base for the exposed prototype of the hybrid bike. It features a parallel-twin engine which is bolted onto a new tubular steel frame with a large electric motor mounted above the transmission. The electric motor derives its energy from a small 48V battery pack located under the seat.

As per Kawasaki, the hybrid powertrain is equipped with a regenerative feature that tops up the battery when low on charge. Another interesting aspect of this hybrid motorcycle is that within city limits, the bike would completely run on battery and electric motor, cutting out power from the combustion engine. This mode will be useful when some cities introduce zero emissions zones in the future.

Automated Transmission
The bikemaker has equipped the prototype with GPS technology that automatically switches to electric power as soon as the bike enters city limits. Outside the city limits, the motorcycle will draw energy from both the combustion engine and electric motor in order to boost its performance. The entire system is paired with an automated transmission system with buttons for gear shifts.

The setup comprises an automated clutch and a servo-operated shifter that enables gear shifts through push button changes. Other details revealed from the images include a pair of telescopic front forks and rear mono-shock supporting the tubular steel frame. Stopping power is provided by single disc brakes on both wheels while being linked to dual-channel ABS.

Although no exact timeline for its launch has been confirmed, we won’t be surprised if this motorcycle reaches production within a span of a year.

Blind Spot Warnings Display On Motorcycles

By General Posts

How blind spot warnings could be displayed directly in motorcycle mirrors.

Motorcycle manufacturers are exploring ways of alerting riders to the risk of collision with vehicles in their blind spot.

TOKYO, Sept 30 — Yamaha has filed a new project with the Japanese Patent Office for a system that alerts motorcycle or scooter riders when a vehicle is in their blind spot. This solution takes the form of LED strips placed directly behind the mirrors that face the rider. This solution could prove an effective means of alerting riders to this type of danger.

Most motorcycle manufacturers are actively working on blind spot warning systems. Yamaha recently filed a patent revealing a new technology that displays specific icons directly on the bike’s mirrors.

The idea is to be able to alert riders to dangers quickly and effectively. To do this, the Japanese manufacturer relies on displaying warnings on the bike’s mirrors in case of danger. The solution takes the form of a small screen placed behind each of the mirrors in the bike’s two rearview mirrors, capable of displaying a warning icon in the event of a collision risk, i.e., a vehicle in a blind spot. Note that the system could also display the warning on just one mirror, depending on the side where the danger is located.

In addition to the presence of a vehicle in their blind spot, this device could also warn riders of a risk of collision with another vehicle, when they’re breaking the speed limit or when they receive an incoming phone call. It could theoretically be fitted to a motorcycle as well as a scooter. Still, it remains to be seen whether this solution will eventually see the light of day.

Currently, the most advanced solution in this field is undoubtedly Bosch’s Blind Spot Detection (BSD), which is used in many motorcycle models, including BMW, Ducati or KTM bikes. In the event of a risk of impact with a vehicle coming from the rear, the system emits a sound or displays a visual alert on the screen.

Of course, the easiest & safest way to avoid this type of accident is to turn your head before pulling out or changing lanes, to make sure that there are no vehicles in your blind spot.
