Cadillac is returning to endurance racing with a new prototype in 2017

In two months, Cadillac will return to top-tier endurance racing with its all-new Daytona Prototype International racecar after 14 years away. The car, which adheres to IMSA's new DPi regulations, looks as long, low, and Cadillac-like as anyone could have hoped. It's set to debut at the Rolex 24 at Daytona and will compete head to head with the likes of Mazda and Nissan in what is shaping up to be one of the most diverse and exciting forms of American motor racing in years. The new car will be run by Wayne Taylor Racing, the team that previously fielded the Corvette Daytona Prototype. Wayne Taylor himself has won the 24 Hours of Daytona twice, in 1996 and 2005. He now manages the team and leaves the driving duties to his two sons, Ricky and Jordan. They'll be joined in the cockpit by Max Angelelli, Wayne Taylor's teammate in 2002 at Cadillac's last unsuccessful attempt at endurance racing. To understand Cadillac's new car, officially called the DPi-V.R., you need to understand IMSA's DPi category. Basically, manufacturers are allowed to base their car on one of four chassis that follow the FIA LMP2 regulations. The chassis come from either Dallara, Onroak Automotive, ORECA or Riley/Multimatic. Cadillac will base their car on the Dallara platform. The DPi regulation differ from the LMP2 in two major ways: non-standardized engines and the ability to change certain parts of the bodywork. The DPi regulations are intended to give the variety of the top-tier LMP1 cars at a fraction of the cost. When it came to choosing an engine, Cadillac wanted to power the new car with something kinda sorta production based. The new car will use a naturally aspirated 6.2-liter pushrod V8 that shares some base architecture with the engine in the current CTS-V. While the power output hasn't been announced, expect about 600 horsepower. While that's down compared to the CTS-V, there is far less mass to move around as the Dallara chassis is a svelte 2,050 lbs. Since all the teams will be running different engine configurations, expect restrictors of some sort to help balance the power disparity. The parts of the body work that can be modified - The nose, sidepods, rear wheel arches and rear valance - have all been designed to mimic Cadillac roadcar design elements. Even the wheels look like they were pulled straight from the CTS-V. The front splitter, the floor, and the diffuser are common elements shared with other DPi cars.

MIT puts V2V technology on its 2015 Top Ten list

Of all the technologies swimming around the automotive world, it is vehicle-to-vehicle communication that the Massachusetts Institute of Technology has fished out as one of its Ten Breakthrough Technologies of 2015. It joined emerging tech like brain organoids, supercharged photosynthesis, and Project Loon on the list, and got the nod over autonomous driving because, as the MIT Technology Review wrote, V2V communication "is likely to have a far bigger and more immediate effect on road safety." How so? Because actual cars transmitting data like their location, speed, steering angle, and state of braking to one another at least ten times per second provides a greater degree of awareness than sensor readings and algorithms. The US Department of Transportation and the National Highway Traffic Safety Administration have been working for years on standards and a regulatory schedule for introducing V2V to the marketplace, and Cadillac plans to incorporate V2V into at least one of its vehicles by 2017. Since we've begun the year with a number of stories of cars being hacked into, that got us wondering about the security of V2V communications. In a recent piece by our own Pete Bigelow on what motorists should know about getting their cars hacked into, he wrote that although cyber break-ins are extremely difficult, expensive, and time-consuming to do remotely, V2V is "one more conceivable avenue a hacker could use to impact multiple cars at a given time." So we spoke to Wilmington, Massachusetts-based Security Innovation about it. The automotive consultancy company has been working with the DOT since 2003 on V2V technology and the issues around it - namely security and privacy - and its chief scientist, William Whyte, is the technical editor of the Institute of Electrical and Electronics Engineers (IEEE) 1609.2 standard outlining its security protocols. Those protocols are expected to be finalized by the DOT toward the end of this year and then come into effect in 2016, and the company's Aerolink product is the security solution Cadillac will use. Whyte said, "If you hack into a car, V2V is the hardest place to start," and Pete Samson, the general manager of Security Innovation's automotive team, said "There are ten or 12 alternate attack surfaces" around the car that would make much easier targets.

Cadillac: The standard of what?

Cadillac's tagline "Standard of the World" goes back to 1908 when it won the Dewar Trophy. While you might think that the moniker and the trophy have something to do with a feat of racing and daring-do against a cadre of British, French, and German marques, it's nothing of the sort. Rather, Cadillac achieved the trophy because of interchangeable parts. The parts they were producing back then were so well-made that Henry Leland, who established Cadillac, was able to disassemble three Model Ks, mix up the parts, and then put together three functioning cars. This amazed the Brits who handed him the trophy, and the "Standard of the World" was born. During the past several months, Cadillac has been producing news releases that would seem as though the company is the Standard of the World: "Cadillac Global Sales Rise 44.2 percent in January ... 18 percent in February ... 22.1 percent in March. . .40.9 percent in April ... 33.8 percent in May ... 7.2 percent in June." Like the Dewar Trophy being about manufacturing not performance, things are not necessarily what they seem. That is, Cadillac's growth is predicated on performance in China, not in the US. Through June, its China sales are 80,357 vehicles for the first five months of 2017, versus 72,073 in the US. The China number is a 75.4-percent year-over-year increase while the US number is a 1.6-percent decrease. For the entire globe, Cadillac has sold 164,174 vehicles. Of them, 65,250 were the XT5. That was followed by the ATS, at 34,277 units. In the US, the XT5 is doing reasonably well, as it has moved 29,798 units during the first six months. The ATS, conversely, is doing not particularly well, as it is down 26.2 percent with sales at just 7,209 for the year so far. To put that into some sort of context, know that Cadillac has sold 7,370 copies of the generally derided XTS, which is down 24.7 percent. The CTS is down 36 percent at 5,059 units, and the only other car in the lineup (we'll pretend that the ELR doesn't exist anymore and it shortly won't), the CT6 sedan, is up 172.7 percent – but they have sold only 5,397 CT6s. While Caddy talks a good game about competing with the likes of the BMW 5 Series and the Mercedes E-Class, know that those two sedans have been sold 17,036 and 20,783 times this year in the US respectively. So what is Cadillac chief Johan de Nysschen to do? According to Reuters, it is to cull the lineup.
