Cadillac's Blackwing V8 was the best engine at the worst time

It should be clear that GM knows how to innovate and engineer excellent products when it wants to. Cadillac's 4.2-liter twin-turbo Blackwing V8 is recent proof of that. Yet, as related in an extensive Road & Track piece, the Blackwing became victim to some of The General's bugbears, like the reticence to — for whatever reasons — unleash its excellence everywhere, fund that excellence, and be consistent with that excellence over the long term beyond the Corvette and full-sized pickups and SUVs. The R/T story relates tales told by "several people deeply involved with the Blackwing project" about how an engine 18 years in the making was deprived of its reasons for being in less than three. Starting around 2000, GM spent a dozen years building Cadillac up to the point where the American luxury brand could rationally flip to the chapter called, "Taking the Fight to the Germans, but for Real this Time." The first steps in the plan meant an exclusive platform and an exclusive engine. The platform was called Omega. You know the engine's name. They were going to be the aluminum-blocked fist and velvet glove enabling Cadillac to break on through to the other side of luxury — proper luxury to global standards, that is — with a range of beautiful and dynamic crossovers and sedans. An engineer involved in the project estimates GM poured $16 million into the Blackwing's clean-sheet development. Many more seven-figure sums went into creating the first sedan on the Omega platform, the CT6. The automaker dropped millions again poaching ex-Audi and Infiniti chief Johan de Nysschen, and moving Cadillac's headquarters to New York City in 2014. Further pallets of cash funded the development and debut of the Escala concept at Pebble Beach in 2016. In 2018, GM revealed its dramatically named DOHC twin-turbo V8. Considering what came before, the Blackwing clearly wasn't designed for cars. It was designed for world domination. However, against the backdrop of plummeting sedan sales, the CT6 didn't sell like GM had hoped. The automaker hesitated to marshal another fleet of Brinks trucks to fund entries into a cratering bodystyle. Removing sedans from the world domination equation created more difficult math for the crossovers and the Escala.

Junkyard Gem: 1976 Cadillac Eldorado Convertible

Convertibles rode high well in 1960s America, with Detroit selling more than 500,000 ragtops in 1965, but sales collapsed by the early 1970s and tightening federal crash-safety regulations made it seem less worthwhile to even bother producing new ones. Chrysler halted convertible production after 1971, with Ford following suit by 1973. By the 1976 model year, the Cadillac Eldorado was the last new American car you could buy with a convertible top from the factory, and it appeared that none would ever be built again. I've found one of those "last convertible" Eldorados in rough-but-identifiable condition in a Denver junkyard. As it turned out, the convertible never really died in America. Car shoppers could still buy new European-made convertibles after 1976, coachbuilders modified new Detroit cars with factory-grade drop-tops, and then Chrysler began selling K-Car convertibles starting with the 1982 model year. Because the '76 Eldorado appeared to be the absolute end of the convertible line, however, buyers thought they were investing in a sure-fire collector car that would be worth vast sums in the not-very-distant future (this belief led to lawsuits against GM later on, when the Cadillac Division resumed production of the Eldorado convertible for 1984). While a one-of-200-made Bicentennial Edition Eldorado with red-white-and-blue trim really is worth plenty these days, an ordinary 1976 Eldorado in beat-up condition doesn't seem worth restoring. This car appears to have sat outside in Colorado with the top down for decades, filling with snow each winter and enduring high-elevation solar irradiation each summer. A 1960s GTO or Camaro might be worth fixing up after falling into this state of disrepair, but not one of 14,000 "last convertible" Eldorados made in 1976. GM's Unified Powerplant Package front-wheel-drive system, which used battleship-strength chains to transmit power to the drive wheels, proved to be extremely reliable on the street, joining the small-block Chevrolet engine and Hydra-Matic transmission in the pantheon of The General's Greatest Engineering Hits. Even gigantic motorhomes used this system. In 1976, the Eldorado got the last of the 500-cubic-inch (8.2 liter, or litre as GM's marketers spelled it) V8s, rated at a disappointing 190 horsepower and an impressive 360 lb-ft of torque.

Cadillac Super Cruise, a hands-off review

Cadillac Super Cruise won't let you eat breakfast behind the wheel, climb in the back seat or any of the other stupid human tricks displayed on YouTube by Tesla owners. It even won't allow the car to change lanes on its own, like Tesla Autopilot. But it's a big step on the road to full autonomy, a huge convenience on long-distance road trips and a substantial technological triumph for Cadillac. In the simplest terms, Super Cruise is a lane-centering enhancement to adaptive cruise control (ACC). But Super Cruise is anything but simple. Its technical complexity — hence its long delay after first being unveiled five years ago — belies its straightforward operation and intuitive user interface, which I discovered on an almost 750-mile, 11-hour drive in a 2018 Cadillac CT6 between Dallas and Santa Fe to test the system. LOADS OF LIMITATIONS First, let's dispense with the details and disclaimers. Super Cruise is standard on the 2018 CT6 Platinum and a $5,000 option on other trim levels. Because Super Cruise is supported by OnStar — an OnStar operator will call to find out if first responders need to be sent in a worst-case scenario — a three-year OnStar Super Cruise Package is included with the system. Super Cruise has loads of limitations that are probably more concerning to GM's legal counsel than they were to me during my long drive. Some are no-brainers, such as not for use in construction zones or for driving on the shoulder. But the system can also be stymied by adverse weather, poor visibility and faded lane markings. Super Cruise only works on freeways with on and off ramps and a center divider. ACC and forward collision warning also need to be engaged, and the system's cameras and radar sensors can't be obstructed. To keep drivers from looking away from the road for too long — and to keep the system active — an infrared camera on top of the steering column keeps an electronic eye on the driver's seat. GM has over 100 patents alone on this Driver Attention System, including an algorithm that triangulates the nose, eyes and ears in case the camera can't see through sunglasses to make sure you're not nodding off. In addition to the car's visible sensors, another major component of the system is something you don't see: mapping software. But not the kludgy kind that powers in-dash navigation systems.
