Honda ARX-04b endurance racer is coming to a track near you

By Stephen Edelstein Published April 14, 2014

Racing season is upon us, and Honda has unveiled its latest endurance car.

The Honda ARX-04b LMP2 coupe is eligible for competition in the TUDOR United SportsCar Championship, World Endurance Championship (WEC), European Le Mans Series (ELMS), and Asian Le Mans Series.

Note that, unlike the hybrids fielded by Audi, Porsche, and Toyota, the ARX-04b does not qualify for the top LMP1 class in the prestigious WEC, although its place in the pecking order of other race series will vary depending on regulations.

Honda also won’t have a factory team in any endurance-racing series this season. Instead, it will sell cars to private teams.

That doesn’t mean the Japanese automaker cut corners in development, though.

The ARX-04b is the result of a partnership between California-based Honda Performance Development (HPD) and England’s Wirth Research. HPD is already credited with more than 70 victories in the now-defunct American Le Man Series.

The car meets all requirements for competition at the 24 Hours of Le Mans, and is powered by a 2.8-liter, twin-turbocharged V6. The engine is actually based on the 3.5-liter “J35” V6 used in the 2014 Acura MDX and RLX, and 2015 TLX, sharing around 400 parts with production versions.

While it doesn’t boast any form of electrification, the ARX-04b does have low-drag bodywork for improved fuel efficiency.

Other notable features include a refueling safety interlock system designed to lessen the risk of pit fires, and adapted from the one used on all IndyCar racers since 2011.

Look for the Honda ARX-04b to compete in upcoming endurance races. Or, if you’ve got a spare million lying around, start your own race team and buy one yourself.

Eaton, Treehouse to boost home capacity for EV charging, energy storage

Power-management firm Eaton likes to point out that when it launched in 1911, it invested in a new idea -- the very first gear-driven truck axle -- just at a time when both transportation and power management were on the cusp of dramatic change.
More than 113 years later, Eaton is again seeking to lead innovation in the current energy transition.
The power-management firm just signed a deal with Treehouse, an AI, software-enabled installation platform for electrification projects. The end goal: accelerating the electrification of homes for electric-vehicle (EV) charging, energy storage, or heat pumps, while seeking more efficiency and cost savings.
“At Eaton, we’re all-in on the energy transition and we’re making it happen at scale by delivering breakout technologies and industry collaborations needed to delight customers and make it more accessible and affordable,” says Paul Ryan, general manager of Connected Solutions and EV Charging at Eaton.
The partnership will ensure consumers are provided with accurate and fast pricing, as well as access to licensed electricians to deliver code-compliant installations, the companies say.
The collaboration also integrates into Eaton’s “Home as a Grid” approach, which supports the two-way flow of electricity, enabling homeowners to produce and consume renewable energy when they need it, Eaton says.
“For more than a century, power has flowed in one direction—from centralized power plants into homes,” the company says. “Today, there’s a new reality thanks to solar, electric-vehicle charging, energy storage, digitalization, and more.”
Projects to change homes and EVs into energy hubs have multiplied recently.
Last month, Nissan joined ChargeScape, a vehicle-to-grid (V2G) venture that is already backed by BMW, Ford, and Honda. ChargeScape’s software wirelessly connects EVs to power grids and utility companies, enabling consumers to receive financial incentives for temporarily pausing charging during periods of high demand. Eventually, consumers should also be able to sell the energy stored in their EVs’ battery back to the power grid.
In August, GM announced that V2G technology will become standard in all its model year 2026 models. And Tesla CEO Elon Musk has hinted that Tesla could introduce V2G technology for its vehicles in 2025.

Chrysler, Dodge, Jeep and EVs offer big incentives as year nears its end

It’s no secret that automakers and dealerships typically climb over each other to offer the best incentives before the year ends. But this year’s sales season is expected to be particularly competitive, with slowing sales translating to greater urgency to clear inventory.

According to research from Kelley Blue Book, the respected vehicle-valuation firm, overall incentives on new vehicle sales were up by 60% in October compared to the previous year.

Jeep, Ram EREVs will get 690-mile range with new Stellantis platform

A 2025 Ram 1500 Ramcharger sits in a vineyard.

Stellantis, the giant automotive group, is betting big on extending the range of both its hybrid and fully electric vehicles (EVs).

Last month, the company, which owns the Jeep, Dodge, and Ram brands in the U.S., invested nearly $30 million into an advanced wind tunnel at its research center in Auburn Hills, Michigan. The goal is to study airflow around a vehicle’s wheels and tires to further optimize its EVs and boost their range.
