GM claims it's first to sell million 30+ mpg vehicles

As we continue to put together all the data for the year-end edition of By The Numbers, General Motors has announced that it sold more than a million vehicles in the US last year that achieved at least 30 miles per gallon on the highway. More impressively, GM managed this feat using multiple strategies including small vehicle size, turbocharged engines and hybrid or plug-in technologies across four brands (Buick, Cadillac, Chevrolet and GMC) accounting for 13 separate models. This number will grow even more in 2013 thanks to cars like the all-electric Spark, the diesel Cruze, the range-extended Cadillac ELR and the Buick Encore compact CUV.
GM's small car sales were up 39 percent last year helping to attain this million-sales mark for 30-mpg models, and almost 40 percent of all GM sales consisted of cars with fuel-efficient I4 engines. In regards to more advanced means of improving fuel economy, GM says that it plans on having 500,000 vehicles with "some form of electrification" on the road by 2017.

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.

GM reworking mandatory OnStar plans for some 2024 models

For the 2023 model year, GM added its OnStar and Connected Services plan as standard equipment to a large number of Buick, GMC, and Chevrolet vehicles. Folding the $1,500 retail price into the MSRPs of models like the GMC Acadia and Buick Encore plumped up prices beyond the usual year-on-year bumps. Looks like there's a reversal in play for 2024, GM Authority reporting that many of the models fitted with OnStar and Connected Services — now called OnStar Premium — will step down to three years of OnStar Remote Access standard.   OnStar Remote Access comes with these features: Remote key fob, vehicle locate, and remote personalization through mobile and in-vehicle apps. Three additional features can be added to the plan: OnStar Guardian, in-vehicle hotspot, and Super Cruise. Owners can also upgrade to OnStar Premium if they choose.  Higher trims like Buick's Avenir and GMC's Denali, plus the GMC Hummer and the Cadillac Escalade will retain OnStar Premium as standard equipment. That suite starts with Remote Access and adds: Automatic crash response, stolen vehicle assistance and recovery, OnStar Guardian, in-vehicle app access, unlimited streaming, three years of Super Cruise on vehicles with the hardware, and six months of SiriusXM radio. The Escalade puts a cherry on top with three years Sirius XM instead of six months. The Remote Access plan normally charges $14.99 per month. We're not sure yet if GM will subtract the cost of OnStar Premium from the MSRP and add the $540 for OnStar Remote Access, or if the trial period comes free of charge. Even if that's what happens, the change could take nearly $1,000 off the MSRP of a car like the GMC Acadia before any 2024 increases. We'll know more as the 2024MY models roll out and prices are announced. Related Video 2022 Buick Enclave Avenir revealed
