Super Cruise’s failsafes

Even though Super Cruise is not a fully autonomous system, it incorporates redundancies like those used in aircraft to ensure failsafe operation. Before taking off on a 700-mile, 11-hour test drive of the system — and putting my life in its hands without my hands on the wheel — I sat down with Daryl Wilson, lead development engineer for Super Cruise, to get a deep dive into the system and its critical safety backups. Autoblog: First, what makes Super Cruise different from similar systems? Wilson: The key differentiator for Super Cruise is hand-free driving. It's an industry first in that respect. Our competitors require the driver at minimum to place their hands on the wheel with some frequency to ensure that the car knows that the driver is there. We don't. Two key technologies allow us to do this. One is our Driver Attention System, which is our methodology for making sure the driver is engaged with the vehicle and engaged with the road. This is a driver assist system, not a fully autonomous system. So it requires driver engagement. We use an infrared camera that constantly monitors the driver's face to determine the direction they're looking. We're looking for the driver to be what we call on-road — not on the center stack, not to left or right or down. That's all done by the tracking of the face. We also track that the eyes are open. It's infrared because at night you need to illuminate the face and you can't be shining a light into the driver's face. Then we have our lidar mapping that provides a foundation for control and redundancy to ensure safe performance. Autoblog: How does the mapping act as a redundant feature? Wilson: This system is only for use on divided, controlled access highways. What I mean by a divided highway is something more than a painted line between you and oncoming traffic. Whether that's a grassy area in between the lanes or a concrete barrier, anything that separates you from oncoming traffic. That's the divided highway part. The controlled access part is entrance ramps and exit ramps. Not with roads that cross at grade, with traffic crossing at the same level. To do that we geofenced these roads to ensure that operation is only allowed in these conditions. We don't just recommend you use it there; we ensure that you only use it there.

2020 Cadillac CT5 debuts at N.Y. Auto Show as a proper sport sedan

The 2019 Cadillac CT5 is here, and it's not a tweener sedan. After having done battle with the luxury sedan world through cars that were either too large or too small, Cadillac is using the CT5 to take direct aim at the BMW 3 Series, Audi A4, Alfa Romeo Giulia and Mercedes C-Class. Specifically, the CT5 replaces the CTS, but takes on vehicles one class smaller than what the CTS did. So, let's take a look at what Cadillac is bringing to the table. To begin, GM knows it has a winner on its hands with the Alpha platform used on the CTS and ATS and the Camaro, so engineers adapted it to the CT5. This seems like a great start, because we all happen to love the driving dynamics from vehicles on this chassis. The wheelbase is a couple inches longer than the CTS, but the CT5 is a couple inches shorter in overall length. As a result, the wheels get pushed toward the corners of the car, leaving the CT5 with relatively short overhangs in the front and rear. It looks different than both of the to-be-discontinued Cadillac sedans, but we wouldn't call it revolutionary. The rear end isn't quite a "sportback," but it's a "faster" shape, eschewing a traditional sedan's long decklid for a sloping-roof look instead. This shape does come at the expense of rear seat headroom, but we'll dive into the interior later. We got a little preview of the powertrain setup before this official reveal, but details were scarce. The base engine is the recently new 2.0-liter turbo four-cylinder found in the Cadillac XT4. Just as it did in that vehicle, this engine makes 237 horsepower and 258 pound-feet of torque. While it might be down on power compared to the old 2.0-liter in the ATS (272 horsepower and 295 pound-feet) we found it to be incredibly smooth, refined and not lacking in thrust compared to the old unit. We're sure the four-pot will offer sufficient power for the CT5, but the 3.0-liter twin-turbo V6 is lying in wait. This engine makes 335 horsepower and 400 pound-feet of torque. Both engines are paired to a 10-speed automatic transmission and can be had in rear-wheel drive or all-wheel drive in every configuration. So yes, you can get the V6 with rear-wheel drive, thankfully. Cylinder deactivation is also equipped to both these power units — the four-banger is able to run on two cylinders, while the V6 drops to four. Cadillac was entirely transparent about its new pumped-in engine sound strategy, too.

Hertz and GM team up to put 175,000 rental EVs on the road

Hertz and General Motors have announced a significant partnership that will send up to 175,000 electric vehicles into rental fleets across the country. The deal will unfold over the next five years and include vehicles from all GM brands.   The partnership will run through 2027. Hertz estimates that the electric fleet can save as many as 8 billion gasoline-powered miles, removing 1.8 million metric tons of carbon dioxide-equivalent emissions from the air. Hertz says it will invest in becoming the largest renter of EVs in North America and notes that it already has tens of thousands available at 500 locations in 38 states. By the end of 2024, it plans to electrify a quarter of its fleet. Electric rental cars are a great way for travelers wanting to avoid gas, and they make excellent urban commuter cars. Hertz will also likely save a few dollars by avoiding oil changes and other routine maintenance that gas engines need. However, a hidden societal benefit of this deal may come when Hertz’s EV rental customers begin shopping for new cars. Many people are skeptical of EVs for various reasons, including range, charging, ease of operation, and cost. Giving people a low-risk introduction to EVs and the ability to test-drive one without a pressuring salesperson could drive more people to electrics. At the same time, there's also the risk that renters wanting to take their Hertz-GM EV on a road trip into sparsely populated areas may return with charging and range-related horror stories. Hertz currently doesnÂ’t ask what youÂ’re planning to do with your rental, but it does offer a chat service for questions, and range information is presented clearly on each vehicle.
