Cadillac's luxury model LYRIQ is in the final stages of development-luxury

Cadillac engineers recently completed the “80 percent” validation drive for Cadillac‘s new electric SUV called LYRIQ. This is a key milestone in the development of Cadillac‘s first luxury electric vehicle, marking the transition to the final phase before production. Now engineers can focus on fine-tuning the LYRIQ ahead of final production.

General Motors vice president recently said: “Our future is electric”. This applies not only to General Motors itself, but also to their luxury brand Cadillac – we reported. That’s why the market launch of the new LYRIQ electric model is so important. The E-SUV could already be ordered, but was sold out within ten minutes. The new Cadillac is scheduled for delivery in the first half of 2022. Many hours of development went into the country before it could even come to this and will continue to do so until the coming year. To enable a comprehensive evaluation of LYRIQ‘s performance on different road surfaces and in different traffic conditions, Cadillac developed a curated route that included highway, city and country driving scenarios. Under these real conditions, the engineers evaluated the model‘s powertrain quality, system calibration and other elements that directly affect the driving experience.

Cadillac relies on high-tech for the LYRIQ

“We’ve spent countless hours behind the wheel of our LYRIQ test fleet and in virtual test environments to ensure we’re offering our customers a full luxury experience in an all-new electrified package,” said Jamie Brewer, Senior Chief Engineer. “We remain true to our brand promise by placing great value on careful workmanship and intuitive integrated technologies.The 80 percent drive resulted in performance evaluations of key LYRIQ driver control and sensing elements, including a new interior audio signature designed primarily to promote comfort, well-being and also occupant confidence in the vehicle. “We are now fine-tuning the LYRIQ touchpoints,” says Brewer. “As with any development journey, we make tweaks in a number of areas, but we’re almost there. The customers will love this driving experience, and we believe that it will redefine your expectations of electrical luxury vehicles.”An accelerated schedule for the launch of the Lyriq, which has been promoted by progress in virtual development and supporting parallel processes, led the team for testing even to New Zealand. There, the tests were performed in cold weather in August to use the winter on the southern hemisphere and not to wait for the beginning of the season on the northern hemisphere.

The ultium platform is the central structural element of the Lyriq chassis and care, according to General Motors for a low center of gravity, an exceptional chassis stiffness and a weight distribution of almost “50-50” between front and rear axle. These factors give the engineers unprecedented flexibility when it comes to setting up the chassis, which is intended to herald the next chapter in the ride and handling philosophy. “The LYRIQ has exceptional torsional rigidity,” says Todd Bruder, lead development engineer. He continued: “This enabled us to achieve exceptional steering and suspension response while taking the brand’s signature feel of comfort to a whole new level.”

Technologies such as five-link front and rear suspension and frequency-sensitive dampers help optimize the LYRIQ’s ride quality and responsiveness. The five-link front suspension allows engineers to independently tune the suspension bushings, improving ride quality and handling. The frequency-dependent dampers, which will be standard equipment when the LYRIQ is launched, are said to be able to distinguish between smaller bumps and larger bumps on the road. This allows the driver more precise control in changing road conditions and offers more comfort on smoother surfaces.

Already sold out before launch

At the market launch, the LYRIQ will be offered in the exclusive “Debut Edition”. According to GM, a battery pack with 12 modules, a capacity of 100.4 kilowatt hours and an Ultium rear-wheel drive ensure around 340 hp and a torque of 440 Nm. The manufacturer specifies the range with a fully charged battery at around 480 kilometers in advance. The e-SUV offers direct current fast charging with up to 190 kW, with which customers can achieve a range of up to 120 km in around 10 minutes. When charging at home, the LYRIQ can charge its battery at the fastest rate currently allowed by industry standards. Provided it is equipped with the 19 kW Stage 2 charging module, which is said to allow a range of up to 84 km per charging hour.

The reservation books for the LYRIQ Debut Edition are full. According to GM, other models will not be available to order again until next summer through the Cadillac dealer network. Production of the Cadillac LYRIQ will begin in spring 2022 at GM’s assembly facility in Spring Hill, Tennessee. Here, 2 billion dollars were invested to support the production of electric vehicles. Another $2.3 billion will go into an all-new battery cell manufacturing facility.
