Cadillac CT5-V Blackwing rocketing down the front straight at Canadian Tire Motorsports Park (CTMP) as part of the Ron Fellows Driving ExperienceAfter finding my driving skills no match for the capabilities of Cadillac's flagship performance machine, it was time to see what it could really do in the hands of a professional.I never did get his name, but my hot lap driver candidly told me he's quite confident he has more professional racing wins around Mosport (aka Canadian Tire Motorsports Park) than any other driver in history. And that's quite a claim for a facility that's been around long enough to have hosted F1 races in the ‘60s and ‘70s.Ron Fellows aka "The Mayor of Mosport" giving an overview of the on-track activities for the day.AdvertisementAdvertisementIt's also a particularly significant brag when standing just outside the car is none other than Ron Fellows, the "Mayor of Mosport," who not only runs the experience we're taking part in as part of a broader day-long deep-dive into Cadillac's lineup, but who also has won everything from the 24 Hours of Daytona to the 24 Hours of Le Mans.Sitting shotgun in the 668-hp CT5-V Blackwing around the huge elevation changes of CTMP is an incredible experience.GM Technical Center in Markham, Ontario. Home to over a thousand engineers and where the work to integrate Dolby Atmos into the current Cadillac lineup was done.AdvertisementAdvertisementThis event is a unique combo. We spent the morning at GM Canada's technical center in Markham, Ontario, to learn all about the Dolby Atmos systems installed in the Cadillac lineup (more on that in a future article) before heading out to Mosport for some hands-on time with the high-performance V models. We got plenty of seat time, including our own track testing and some time making the most of launch control, which you can see some of here.Cadillac Optiq Chief Engineer John Cockburn explaining why the GM Technical Center in Canada was chosen to lead the Dolby Atmos integration and just how physiological the experience is.Making the event more unique is that it combined both influencers and journalists. And while it's easy to get snobbish about journalistic expertise, there's a lot you can learn from influencers. For example, while the journalists (myself included) are more interested in steering feel, braking performance, and lateral g-forces, the influencers want to know: how fast did you go up the back straight?Again, a journalist will tell you that maintaining momentum through the corners is where the real speed on a track lies. But you know what: most folks really just want to know how fast you went.AdvertisementAdvertisementThat realization flashed into my mind on our second hot lap around the track as we exited the tight turn 5 sequence and launched onto the back straight. On lap one, the speeds we got to in a road car were beyond what I had expected-even for a seasoned pro. So, looking to grab some proof-I'm not sure I'd believe my own eyes at these speeds- I fight to grab my phone from my pocket and press the record button as the car is being flicked through two immediate right turns.I'm then fighting to stabilize my hands and hold focus on the massive digital speedometer that dominates the dash in front of the driver.From third gear, the supercharged V8 engine whines and howls as the gears change from 3rd to 4th to 5th. Ground speed is sitting at around 112 mph (180 km/h) as the car hits 6th. From there, things smooth out as the power keeps piling on as we gradually rise in elevation. My view out the side of the car amplifies the speed as the trees come into view and leave my periphery before I even have a chance to blink or think.Paddle shifting into 7th, the tachometer isn't spinning numbers as fast as before, as the super sedan fights physics with raw power. It's then that we crest the highest point on the back straight and feel the mildest sensation of the car lifting on its suspension. Not a second later, I think I see it: 156 mph (251 km/h) on the readout.Then instantaneously, the first of the braking cones is upon us, and the speed on the digital readout drops to 137 mph (220 km/h) and then 123 mph (198 km/h).I laugh out loud. What an insane feat of engineering this is. Loads of fun in my own hands, with more capability than I can grapple with; in the hands of a truly experienced driver, it's monumental.Become an AutoGuide insider.
