Cadillac to make America's only hands-free drive technology even smarter for 2021 model year

Cadillac already offers the only hands-free driver assistance feature available on a vehicle in the U.S. For the 2021 model year, the company is enhancing Super Cruise adding, among other technology, automated lane change functionality. This new capability will allow users to achieve hands-free lane changes on compatible highways when they make a request and certain conditions are met.

The new technological enhancements are made possible by the new General Motors digital platform, which allows for more electrical bandwidth and data processing power.

Here's how the lane change functionality works. According to Cadillac,

When Super Cruise is engaged, the driver can either tap or fully latch the turn signal to indicate that they would like to change lanes. This will prompt the system to look for an acceptable opening in the indicated lane, while also taking time to let other cars know that a lane change is imminent. If the system determines that the indicated lane is open, the vehicle will merge into said lane. The driver attention system will continue to require the driver to focus on the surroundings during the lane change.

Upon initiation, the gauge cluster will display messages letting the driver know when the automated lane change has begun, or if lane change is unavailable and changing lanes must be manually completed by the driver. The system will display messages, such as "looking for an opening" or "changing lanes" to keep the driver informed on the status of the lane change.

"In order to add automated lane change and provide our customers with the same level of confidence that they currently have in Super Cruise, we made improvements to both our software and hardware," said Mario Maiorana, Super Cruise chief engineer. "This included improving rear-facing sensors and advanced software algorithms so that the system can confidently track vehicles approaching from the rear. As a result of these improvements, we are able to ensure that Super Cruise will hold in its current lane and only change when a sufficient gap exists."

Cadillac has made other improvements to the system including richer map information to enable automated lane change and improved functionality through turns and highway interchanges, improved software for better steering and speed control, and easier and more intuitive Super Cruise functionality that allows drivers to more easily engage with the system.

Super Cruise launched in 2017 and currently is available for use on more than 200,000 miles of compatible highways in the U.S. and Canada.

Enhanced Super Cruise with automated lane change will be an option on the 2021 CT4 and CT5 sedans and the 2021 Escalade when those vehicles become available in the second half of 2020.

Nuts & Bolts

 
 

The Lotus Exige Sport 410 20th Anniversary debuted last year to celebrate the milestone birthday of the model.

Lotus is turning the page. The company, now majority-owned by Geely, the parent company of Volvo and Polestar, is moving into more exotic territory. That means that it needs to bid adieu to three models as part of a larger Vision80 strategy.

The Lotus Evora, Exige, and Elise will exit the lineup after 2021. Lotus has announced that their production will end by December 31, but an exact manufacturing timeline is publicly unknown. Replacing the models is a new series of sports cars based on the Lotus Type 131 prototype, among others.

The new cars will be manufactured at a facility in Hethel, Norfolk, England. The strategy will ultimately result in the relocation of two Lotus sub-assembly facilities into one central operation in Norwich to support higher volumes of production and sales.

That move is a £100-million-plus investment in the facilities that includes hiring of 250 employees. This is in addition to the 670 employees that the company has recruited since 2017, when Geely and Etika took ownership of the company.

The Lotus Elise debuted in 1995 showing off a body made of extruded and bonded aluminium, and lightweight composites. In May 2020, the Lotus Elise Classic Heritage Editions debuted, showing off unique paint jobs that are a nod to days past, and offering an enhanced exterior and interior spec over the Elise Sport 220 on which they're based.

In 2000, the Exige launched as the Lotus 'race car for the road'. In June 2020, the company debuted the Lotus Exige Sport 410 20th Anniversary to mark the model's birthday.

Lotus launched the Evora in 2008, marking the company's return to the super sports car sector. In January 2020, a cheaper version of the car, designed to better fit the daily driver lifestyle, was offered.

A plug-and-play digital instrument pack was made available in mid-2020 giving drivers of the three cars in the current lineup access to lap recording ability for over 4,000 race tracks.

By the time production is over, Lotus will have sold 55,000 units of the Elise, Exige, and Evora combined.

Lotus recently released video of the forthcoming Evija hypercar taking to the track, unleashing its 1,973 horsepower. The company's engineering team has bragged about its capability and it's safe to say a lot is expected of the model.

Though they're looking forward, the company is also giving an approving nod to its past, delivering its first Certificate of Provenance to a 1981 Turbo Esprit that was driven by Margaret Thatcher. Further certifications are underway.

In April, Lotus celebrated the 35th anniversary of Ayrton Senna's first Formula 1 win (in a Lotus) with a special edition podcast dedicated to the late, great racer.

The 2021 Nissan Rogue is made from recycled aluminum.

While General Motors is busy readying its Spring Hill, Tennessee plant to run strictly on solar power, Nissan is making its Rogue out of recycled metals just down the street. The 2021 Nissan Rogue is the company's first global model built using a closed-loop recycling system for aluminum parts.

Using a closed-loop recycling system has several benefits. It saves 90 percent of the energy that would normally be used to create the parts that are now made of recycled parts. This type of system also helps reduce carbon dioxide emissions compared to the process of making products out of raw materials.

The process starts when scrap metal is shredded and collected through a pneumatic system. Nissan then separates the different grades of aluminum in order to ensure that the high-quality scrap is collected and sent to suppliers according to which parts they supply. Different grades of material are used to make different parts of the vehicle.

The scrap is then made into sheets of aluminum, which is delivered in rolls to Nissan where it is transformed into parts for the Rogue. The hood and doors of the 2021 Rogue are stamped from the aluminum alloy.

Aluminum, which is lighter than steel, is used to reduce vehicle weight, which helps to improve fuel efficiency and power performance of the vehicle.

Nissan redesigned the Rogue for the 2021 model year. It is more powerful and spacious than its predecessor. The Rogue is also chocked full of family-friendly features and fresh technology including a new high-tech driver information screen.

Nissan builds the 2021 Rogue in Kyushu, Japan, and Smyrna, Tennessee. As part of the recycling process, Nissan has collaborated with Kobe Steel, Ltd. and UACJ Corp. in Japan, and with Arconic Corporation and Novelis Inc. in the U.S.
