GM removes start/stop from full-size trucks and SUVs with V8 engines

GM is removing start/stop technology from a number of its popular full-size SUVs due to the ongoing chip shortage. This follows the removal of cylinder deactivation technology from some of its trucks, which was also due to the chip shortage. GM Authority first reported the news, but we’ve just confirmed everything with a GM spokesperson.  The following 2021 model year vehicles will be affected: Chevy Tahoe, Chevy Suburban, GMC Yukon, Cadillac Escalade, Chevrolet Silverado 1500 and GMC Sierra 1500. Only versions of those vehicles built with the 5.3-liter V8 or 6.2-liter V8 and mated to the 10-speed automatic will have the tech removed from them. Only vehicles manufactured on or after June 7 will be affected. “By taking this measure, it will enable us to continue production of our high-demand full-size SUV and pickups as the industry continues to rebound and strengthen,” GM said in a statement. Those who ultimately buy one of these vehicles without start/stop technology will receive a $50 discount off MSRP for their troubles. Losing this fuel-saving tech could be a big negative for some, but we know many folks turn it off anyway. Not having to press the button to deactivate start/stop every time could actually be a positive if youÂ’re part of the camp who does that already. 2021 Cadillac Escalade Sport Platinum View 27 Photos On the downside, GM says “most of the affected vehicles will experience a minor reduction in fuel economy.” We donÂ’t have revised window stickers in hand to know how each model will be affected, but any 1 mpg reduction will be rather impactful for vehicles rated as low as these trucks already are. Any reduction will be seen in the city mpg rating, so take the kind of driving youÂ’re going to be doing into account before purchasing. When it comes to greenhouse gas compliance rules, GM says it doesnÂ’t foresee this impacting the companyÂ’s average fleet score. It also intends to begin adding start/stop back to these models as soon as possible, but there will be no retrofit effort made to fit the tech to vehicles already built without it. “Our supply chain organization continues to make strides working with our supply base to mitigate the near-term impacts of the semiconductor situation,” GMÂ’s statement reads. “GM continues to leverage every available semiconductor to build and ship our most popular and in-demand products, including our highly profitable full-size trucks and SUVs for our customers.

Here's how Cadillac made its Magnetic Ride Control suspension quicker and smarter

Bugatti makes the world's fastest car, but Cadillac claims it has developed the world's fastest suspension. Its fourth-generation Magnetic Ride Control technology receives hardware and software tweaks to deliver a more comfortable ride and sharper handling. It's offered on some variants of the CT4, CT5 and the Escalade. Introduced in 2002 on the Seville STS, this self-adjusting suspension is not as complicated as it might sound. It relies primarily on electromagnets that emit a magnetic field, and a magnetorheological fluid whose viscosity changes depending on the strength of the magnetic force. Sensors scan the road up to 1,000 times per second and send the information they gather to the electromagnets, which then alter their magnetic field as needed to modify the fluid's viscosity. The fluid is in the shocks, so making it thicker returns a firmer ride, and vice versa. In simpler terms, Magnetic Ride Control leverages chemistry and physics to make the ride sporty, comfortable, or somewhere in between -- all in the blink of an eye. By reacting to the changing magnetic field, the fluid-filled shocks filter out road imperfections and maximize tire contact with the road to deliver more precise handling. Cadillac began developing the fourth-generation system by improving the hardware. The in-wheel accelerometers are more accurate than before, the inertial measurement unit is more precise, and the damper fluid formula was changed for quicker response times and a smoother ride. Engineers then turned their attention to the system's software. They notably gave the sensors the ability to process a wider selection of input and output signals, which translates to a wider spread between comfort and sport. And, they made the response time up to 45-percent quicker. All told, the fourth-generation Magnetic Ride Control technology performs better under heavy braking and hard cornering, it delivers more consistent performance, and it reads the road more accurately. Cadillac proudly notes these are the most comprehensive updates it has made to the system in nearly two decades. Magnetic Ride Control comes standard on the 2021 CT4-V and the 2021 CT5-V, and it's bundled into the CT5's V Performance package, which also includes a mechanical limited-slip differential. It's also standard on the Sport and Platinum variants of the 2021 Escalade, and it's part of the Premium Luxury trim's Performance package.

Recharge Wrap-up: LA Auto Show may feature updated Cadillac ELR, Uber expands Chicago HQ

A Kentucky man has converted his 1939 Dodge pickup to an electric vehicle. Al Gajda of Lexington built the electric truck, which he now uses as his daily driver. "I take advantage of any excuse to drive it; just banging around town, errands, short runs on the interstate, delivering my granddaughter to school in the morning," he says. It is powered by a lithium-ion phosphate battery, which is mounted in a wooden box on the truck bed, and gets about 100 miles per charge. Read more at the Lexington Herald-Leader.

Production of the Toyota Rav4 EV has ended. The shipment of the final Toyota EVs concludes Toyota's deal to source batteries from Tesla. Of the 2,600 Rav4 EVs to be produced, there are probably just a few hundred left to be sold, most of which are likely to be gone by the end of October. Read more at Inside EVs. Cadillac will likely show an improved version of the ELR at the Los Angeles Auto Show in November. The 2016 ELR will include unspecified "engineering enhancements," according to Cadillac spokesman David Caldwell. There will be no 2015 model, as the 2014 model will be sold until the 2016 ELR goes on sale in the first half 2015. Read more at Edmunds. Uber executives, along with Illinois Governor Pat Quinn, have announced a major expansion of the ride-hailing company's Chicago headquarters. Uber also plans to add 420 jobs by the end of 2016. "Uber's new expanded headquarters will allow the company to continue its rapid growth and serve its riders and drivers throughout Illinois," says Governor Quinn. Last month, Quinn vetoed legislation that would have put restrictions on companies like Uber in the state. Read more in the press release below.
