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.

2016 Cadillac CTS-V First Drive [w/video]

A million insects lost their lives today. Boxelder bugs and mayflies making the ultimate sacrifice in Elkhart Lake, their carapaces no buffer against a rocketing rectangle of safety glass. Their bodies gorily streaking into spangles along the diamond-faceted face of the Cadillac CTS-V. Road America is a four-mile ribbon of pavement snaking its way through the emerald center of the country's northern heartland. Since the 1950s it's seen uncountable fields of diverse racing machinery rocket over its hills and around its 14 corners. I would imagine that on those occasions the tramping of onlookers and hubbub of vehicles, both competitive and commonplace, would dissuade a great number of our six-legged friends from making their way onto the track. But today it's just me turning laps. Inconceivably just one journalist, driving the baddest roadgoing Cadillac ever made, on one of the loveliest circuits America has ever carved out. So big-winged bugs made it out to me in a vast array and a tragic sum, and I drilled through them oblivious to anything but one of the greatest days of driving I've ever had. Cadillac has turned its CTS-V from a performance sedan to a monster. For 2016 Cadillac has turned its CTS-V from a performance sedan to a monster worthy of the carnage described above. The words "epic" and "awesome" are hilariously overused on the Internet, but in the case of the CTS-V's 6.2-liter supercharged V8, their literal meanings are fitting. The capacity to produce 640 horsepower and 630 pound-feet of torque is astounding. Feeling those outputs come to growling life under my foot arch, uncorks different reactions in my brain as the day wears on: first trepidation, next cautious optimism, finally red-eyed bloodlust. A glance at the power and torque curves will show you that the charged V8 behaves more like a naturally aspirated thing than a turbo'd on/off switch. Peak torque arrives at 3,600 rpm, horsepower at 6,400, giving the engine lovely, linear power delivery. Even with top torque happening near the middle of the tach, there's no small amount of the stuff when the engine first spins up, so launching all 4,145 pounds of Detroit iron still feels exotic. Launching all 4,145 pounds of Detroit iron still feels exotic. On the roads around Wisconsin, using all of the available power is hardly advisable, but I have no trouble driving this fast car slowly (sort of).

Why we can't have better headlights here in the U.S.

It wouldn't be a European auto show if we weren't teased with at least one mainstream vehicle we can't have here. At the Geneva Motor Show last week, the small but vocal contingent of shooting-brake buffs lamented that the Mazda6 wagon won't be coming to our shores, although they can take comfort in the fact that the vehicle won't get the torquey 250-horsepower 2.5-liter turbocharged gasoline engine we'll get here. Mercedes-Benz also announced a new headlight technology in Geneva that likely won't be available here anytime soon. It's just the latest in a long line of innovative and potentially lifesaving front-lighting solutions that the federal government doesn't allow in this country due to outdated standards — and a current lack of leadership at the U.S. Department of Transportation. Mercedes-Benz's new Digital Light system that debuted in Geneva uses a computer chip to activate more than a million micro-reflectors to better illuminate the road ahead. The Digital Light headlamps works with the vehicle's cameras, sensors and navigation mapping to adjust lighting for the given location and situation and to detect other road users. The Digital Light technology also serves as an extended head-up display of sorts by projecting symbols on the pavement ahead to alert drivers to, say, slippery conditions or pedestrians in the road. And it can even project lines on the road in a construction zone or through tight curves to show the driver the correct path. Digital Light will be available on Mercedes-Maybach vehicles later this year, although like any technology it's bound to trickle down to less expensive vehicles. That is, if we ever get it here in the U.S. Audi, a leader in automotive lighting, has repeatedly run into snags trying to bring state-of-the-art car headlights to the U.S. The German luxury automaker's recently introduced matrix laser headlight system, which performs many of the same trick as Mercedes-Benz's Digital Light, also isn't legal on U.S. roads. And five years after the introduction of its matrix-beam LED lighting, which illuminates more of the road without blinding oncoming motorists with brights by simultaneously operating high and low beams, Audi still can't bring that technology to the U.S. either.
