Recharge Wrap-up: Lyft partners with Didi Kuaidi, Cadillac uses ultracapacitors

Lyft and Chinese on-demand transportation venture Didi Kuaidi have announced a partnership. Additionally, Didi Kuaidi is investing $100 million in Lyft. The two ridesharing companies will share technology and provide interoperability between platforms. For users, this means it will be easier to get around when traveling between the US and China. "In today's rideshare environment, where every region presents a unique set of challenges and opportunities, partnering with the homegrown leader is the winning approach to Chinese expansion," says Lyft President and co-founder John Zimmer. Learn more in the video above, and in the press release below. Car2go has announced service in Miami Beach, FL. Beginning October 1, the one-way carsharing service will expand its boundaries beyond its current Miami service area to include neighboring Miami Beach. "We're thrilled to see car2go expand to Miami Beach," says Miami Beach Mayor Philip Levine. "Miami Beach residents and visitors are increasingly seeking new, environmentally conscious options to move around North, Middle, and South Beach, and carsharing is an important part of realizing that vision."

It allows for faster charging without the customer having to upgrade their electrical service panel. Delivering about 20 miles of range per hour of charging, the HCS-30 EVSE can charge most EVs in about four hours. Pricing begins at $565. Read more from ClipperCreek. Cadillac will use ultracapacitors in its stop-start systems for 2016. Rather than relying on battery power to run electrical systems while the engine is not running, the utracapacitors can provide a stable flow of energy without losing lifespan to repeated cycling. Supplied by Maxwell Technologies, the ultracapacitors are also lighter than batteries and, according to Cadillac, provide smoother restarts. The 2016 models to use the updated stop-start technology as standard will be the ATS and CTS, with the exception of the V performance variants. Read more at Green Car Reports.

GM patent reveals new two-stage turbocharger

Modern turbochargers may be some of the best ever made, but performance is something that engineers are always trying to improve. According to GM Inside News, General Motors (GM) is hoping to alleviate some of the negative aspects of a two-stage turbocharger setup with a newly-patented design. The patent, that was filed on May 19, 2016, reveals a clever bypass system that allows the engine, a four-cylinder unit, to optimize both the low-pressure and high-pressure inlets for its respective functions. According to the filing, a conventional two-stage turbocharger setup is engineered to allow both turbines to operate simultaneously at low and mid engine speeds. At high engine speeds, only the low-pressure turbine works. The setup can't isolate either the low or high pressure side, which can impair low-end performance. GM's new two-stage turbocharger setup looks to eliminate this by linking the high-pressure turbo to the exhaust manifold through the high-pressure inlet duct. The low-pressure turbo is attached to the high-pressure turbo by a low-pressure inlet duct, which is linked to a connecting channel. A single actuator that is housed in the exhaust manifold creates a bypass that can opens the high-pressure inlet or close the connecting channel. Depending on what the engine load and speed is, the ECU guides the actuator—a single rotating spindle with discs corresponding to flanges on the high and low pressure sides—to isolate one of the two turbos. Isolating the turbos allow the respective inlets to be engineered for the best possible fluid dynamic performance. The setup should increase performance and decrease lag. There's no word on what car this setup will make an appearance on, but it will most likely be used in premium vehicles before trickling down to the rest of GM's vehicles.

Johan responds to critics again about Cadillac's NY move

Cadillac's new President Johan de Nysschen has faced a fair amount of criticism since assuming his position at the head of the American luxury manufacturer. From the company's move to New York City to a controversial new naming scheme, the first few months of his tenure have not been smooth sailing. Now, the embattled exec is firing back against his critics, notably Automotive News Editor-in-Chief Keith Crain, in a new column running in AN.
De Nysschen countered Crain's claim that the move to the Big Apple, "can only mean that someone wants to live in New York."
"The relocation decision is entirely unrelated to the personal living preferences of any Cadillac executive. No corporation would tolerate such indulgence by its leadership," de Nysschen wrote. "It is about structurally entrenching a challenge to the status quo by reinforcing the psychological and physical separation in business philosophy between the mainstream brands and GM's luxury brand."
