If Cadillac’s smart, the CT5 will be a CTS without baggage

Cadillac is, mercifully, about to rationalize its lineup, something that's been a long time coming. The CTS is one of those cars that gets admiration from reviewers, like us, for a concerted effort from GM to engineer an underlying platform that matches the Germans in terms of raw dynamics. From buyers, it gets not even a shrug as they, oblivious to its existence, walk right into BMW and Mercedes dealerships. The reasons for this have a lot to do with the sheer brand recognition, and the image, of the German competitors. You can't really lay that all at GM's feet, but what you can do is critique the uninspired drivetrain selection. The 3.6-liter V6 is a crude implement, making its 335 horsepower roughly. The BMW's equivalent inline six makes its power smoothly, with modern forced induction. There's no directly comparable E-Class sedan until you get into the V-Sport versus E43 situation, but the turbo four is smooth. And the interior? No question. The Mercedes is jaw-slacking. The story for the CTS's turbo four is largely the same. Some blame also has to be leveled at the first- and second-generation CTS sedans, which adopted an odd strategy: sell a slightly larger sedan to folks looking at 3-Series, A4, and C-Class, but at about the same price. Folks weren't interested in a larger car for the same money. Despite the third-gen CTS's growth into the 5-Series size class, the CTS still seems like an odd in-betweener in the sport luxury segment – psychologically, if not physically. CTS sales are in the toilet in 2017, and GM is smart to shake things up. So with the announcement that Cadillac head honcho Johan de Nysschen has finally been allowed to kill off underperforming models, the CTS is toast. (As is the ATS, and much more importantly, the XTS – a shambling dinosaur of a sedan.) What's next is the CT5, and that's what we're interested in now. Cadillac has until 2019 to figure out what the CT5 actually is. That isn't a lot of time, so our money is on it being a repositioned, rationalized CTS. The platform's not bad; it's heavier than the larger CT6, but it's fairly modern. Sadly, it's unlikely that any of the standard powertrain options will get a revamp, but maybe some additional sound deadening or an active engine mount system to reduce NVH will quell the V6's bad habits.

Cadillac prepares to top its own 'Ring record with upcoming new CTS-V

It was a big deal back in 2008 when the original Cadillac CTS-V clocked a lap time of 7:59 at the Nürburgring, making it the fastest sedan ever to lap the Nordschleife to that date. Not many four-doors have bested that time since - the list consisting pretty much only of the Porsche Panamera Turbo - but now hot hatches are lapping faster than that, so you can bet that the new one will manage an even better time.
Now we've spotted the upcoming new CTS-based performance sedan several times before undergoing testing in locations around the world, but this is the first time we've seen it at the Nürburgring, apparently using the Goodyear Dunlop test facility as its base of operations (and still wearing Michigan manufacturer plates, incidentally). Considering how well the outgoing CTS-V performed and how much further you can bet Cadillac will push the envelop this time around, a new sedan lap record is almost a certainty - and we can only hope for an all-out war between Europe's performance sedan power houses to ensue.

Combine a self-driving car with V2V, and here's what happens

Transportation engineers have started laying the groundwork for a traffic world in which cars communicate with other cars and infrastructure like bridges and traffic lights. How about an environment in which cars talk to pretty much everything and everyone? In a preview of its offerings at the upcoming Consumer Electronics Show, Delphi Automotive will deploy just such a concept. Engineers have designed a system that communicates with traffic signals, street signs, pedestrians, cyclists, even to fry pits and parking garages along a driver's route. To date, engineers and researchers across the auto industry have focused on the technical and safety-oriented foundation of future vehicle-to-vehicle communications, which could help cars share information about everything from traffic tie-ups to upcoming road hazards. Beyond those building blocks, many have projected that V2V could also include more consumer-focused features. Delphi's system, dubbed V2Everything, might be the first that combines those sorts of features in a tangible package. At CES in Las Vegas, scheduled to begin the first week of January, company officials say they'll demonstrate in real-world conditions how V2V technology can be used in an autonomous vehicle to provide a range of critical safety information and leisure and convenience options for riders. The first V2V technology installed on a production car is slated to appear on the 2017 Cadillac CTS. "We imagine a world with zero traffic accidents," said Jeff Owens, Delphi's chief technology officer. "To get there, we will need a convergence of active safety, sensor fusion, connectivity platforms and advanced software." Such software might allow a vehicle to start searching for and reserving parking spots at a programmed destination long before arriving. It could allow riders to place their McDonald's drive-through order from the road and have the food ready for pickup along the route. For the drive itself, the Delphi-equipped car can stay updated on the status of traffic lights around Las Vegas, and can anticipate yellow and red lights. Using smart-phone technology, the car can detect pedestrians and cyclists that may otherwise be hard to see. It can send messages to friends or family to notify them of a driver's location. Some of those features have been available on third-party apps or individually developed by automakers. But this system marries them together in a single system that is tailored for use in self-driving cars.
