Junkyard Gem: 1998 Cadillac Catera

A decade or so after Ford tried to swipe some US-market sales from European luxury marques by selling the German-built Ford Scorpio with Merkur badging, General Motors opted to sell the German-built Opel Omega luxury sedan as a Cadillac. The Catera was a reasonably nimble rear-wheel-drive sedan with a 200-horse DOHC V6 engine, and its badge-engineered nature made it a much less costly gamble than, say, the Cadillac Allante, which had its bodies built in Italy and flown to Michigan for assembly. Unfortunately, it had no manual transmission option, and Americans who remembered the miserable US-market Opels of the 1970s were put off by the Catera's Opelness. Its $29,995 list price was quite a bit cheaper than that of the (slightly less powerful) $39,800 BMW 528i and a bit less than the (slightly more powerful) $33,585 Acura 3.2 TL's cost, but the Catera didn't sell in large numbers. This one made it to a respectable mileage figure, and the nice interior shows that it was well-cared-for during its 18 years on the road. The ads for the Catera featured a cartoon duck named Ziggy. Fast, fun, fiendishly flexible! By 2000, Cadillac had ditched the duck and was touting the Catera's value. Related Video:

GM patent reveals new two-stage turbocharger

Modern turbochargers may be some of the best ever made, but performance is something that engineers are always trying to improve. According to GM Inside News, General Motors (GM) is hoping to alleviate some of the negative aspects of a two-stage turbocharger setup with a newly-patented design. The patent, that was filed on May 19, 2016, reveals a clever bypass system that allows the engine, a four-cylinder unit, to optimize both the low-pressure and high-pressure inlets for its respective functions. According to the filing, a conventional two-stage turbocharger setup is engineered to allow both turbines to operate simultaneously at low and mid engine speeds. At high engine speeds, only the low-pressure turbine works. The setup can't isolate either the low or high pressure side, which can impair low-end performance. GM's new two-stage turbocharger setup looks to eliminate this by linking the high-pressure turbo to the exhaust manifold through the high-pressure inlet duct. The low-pressure turbo is attached to the high-pressure turbo by a low-pressure inlet duct, which is linked to a connecting channel. A single actuator that is housed in the exhaust manifold creates a bypass that can opens the high-pressure inlet or close the connecting channel. Depending on what the engine load and speed is, the ECU guides the actuator—a single rotating spindle with discs corresponding to flanges on the high and low pressure sides—to isolate one of the two turbos. Isolating the turbos allow the respective inlets to be engineered for the best possible fluid dynamic performance. The setup should increase performance and decrease lag. There's no word on what car this setup will make an appearance on, but it will most likely be used in premium vehicles before trickling down to the rest of GM's vehicles.

Cadillac's de Nysschen takes aim at Porsche 911, Cayenne

Johan de Nysschen has big plans for Cadillac. He's moved the brand from Detroit to New York, revamped its model nomenclature, and planning a raft of new models for the near future – including a $250,000 luxury sedan to take on the likes of Rolls-Royce and Bentley. But the veteran executive of luxury automakers has some more performance-oriented machinery in mind, too. Speaking with Car and Driver at the Los Angeles Auto Show last week, de Nysschen suggested Cadillac could be ready to launch a flagship sports car sometime in the next decade. The halo model would take aim at the Porsche 911 and do for Cadillac what Audi did with the R8, Mercedes is doing with the AMG GT and Acura once did (and is aiming to do again) with the NSX. Just what form it would take remains a big unknown, but de Nysschen indicated that the brand would need to be built up further before the sports car would be launched, lest it emerge too detached from Cadillac's image. The last time Cadillac delved into that territory was with the Corvette-based XLR, of which it sold only 15,000 or so examples – far below initial targets. The 911 rival isn't the only performance model de Nysschen has in mind, however. He plans to further expand the V series into a more substantial sub-brand to include a crossover to take on the likes of the Porsche Cayenne Turbo, BMW X5 M and all those many AMG-tuned Mercedes utilities. The idea of an entry-level model to slot in below the ATS was mooted as well. A range of diesel engines are slated to help Cadillac break into overseas markets in similar fashion to how Maserati has expanded its market reach with oil-burning versions of the Ghibli and Quattroporte. And we wouldn't be surprised to see Cadillac get in on a new flagship SUV being launched by Opel in Europe, either.
