Mosport: Canada's First Grand Prix Home

Automobilista-2-Audi-R8-LMS-GT3-Evo-II-Mosport.jpg
Automobilista 2's v1.6 update saw the arrival of three new North American tracks - and while most will know Sebring and Road Atlanta, not too many might be aware of Mosport.

A bumpy airfield circuit, a winding blast through the hills of Georgia (USA, not Eastern Europe), and a Canadian classic - the trio of new circuits added to Automobilista 2 via the v1.6 update as part of the IMSA Track Pack are certainly exciting. And while most sim racers will know Sebring and Road Atlanta, Mosport might fly under the radar for some - and it really should not, in my opinion.

Located northeast of Toronto, Ontario, in what is close to "the middle of nowhere" territory, Mosport is one of those few circuits that have not seen a single layout change throughout its decades-long existence. The track opened in 1961, and it still uses the exact same, blisteringly quick trajectory. Add in some serious elevation change, particularly in the first half of the lap, and you are in for a treat.

Of course, run-offs and facilities have changed over the years, the track has been widened and the crest towards the end of Mario Andretti Straightaway was lowered (thanks to @Emery for bringing that up!), but the fact that the layout itself remains the same is remarkable. Road America would be another example for this, save for the addition of the motorcycle chicane at The Kink - but that did not alter the original layout.

F1 Debut In 1967, Tragedy In WSC​

Anyway, back to Canada. Mosport, or Canadian Tire Motorsport Park, first saw Formula One action in 1967, making it F1's first Grand Prix home. The track would alternate with Mont Tremblant for the next few years, but from 1971 onwards, Mosport was the host of the Canadian Grand Prix. The only exception was 1975, where the event was not held at all, supposedly over "a financial disagreement between the track and the Formula One Constructor's Association", as Canadian sports outlet TSN put it.

F1's final trip to Mosport happened in 1977, after which the Canadian Grand Prix moved on to Montréal. That did not mean high-level racing would skip the track, though: Sportscar racing continued, and does to this day. Even the World Sportscar Championship ran here, with the 1985 1000 km of Mosport being the final time.

Group C beasts at a relatively small, high-speed circuit like Mosport are exciting, but dangerous.

The race, sadly, was a tragic one. With Group C cars flying around a circuit that was no stranger to serious accidents - look no further than John Surtees, who was lucky to survive life-threatening injuries sustained at a 1965 crash in a Lola T70 - disaster struck early on. Driving a Porsche 962C for Kremer Racing, German Manfred Winkelhock suffered a tire failure when racing through Clayton Corner, crashing into the concrete barrier.

Winkelhock, who was also an F1 driver for RAM-March at the time, sustained head injuries that proved unsurvivable, as he succumbed to them the following day. It took marshals 25 minutes to extricate him from the wrecked 962. A mere three weeks later, Stefan Bellof died in the older-spec 956 at Spa-Francorchamps - a heavy blow to German motorsports, and one that apparently even led to a young Michael Schumacher questioning whether or not what he loved doing was something to continue.

The Moss turns, named so after Sir Stirling Moss, who suggested that instead of the carousel-style hairpin, this two-corner approach would be a bigger challenge instead.

Stock Cars & Sportscars​

In the following years, Mosport hosted stock car and GT racing as well, and it was also a mainstay on the Atlantic Championship series, a junior series on the North American open-wheel ladder that ultimately led to IndyCar, and later, CART or ChampCar.

However, sportscars remained even more present. The American Le Mans Series ran at Mosport from 1999 to 2013, and IMSA has had multiple stints, currently racing LMP2 and GTD machinery in Ontario. Today, the NASCAR Canada Series, the Trans-Am Series, the Sports Car Championship Canada and the Canadian Superbike Championship round out the calendar of the circuit.

A Fun High-speed Adventure In AMS2​

And while the current crop of Hypercars - or GTP, if you are so inclined - does not actually race at Mosport, that does not mean that we cannot do just that in sim racing. Automobilista 2's hybrid-powered prototypes are excellent fun around the sweeping circuit, and the braking zone into the first of the two Moss turns is quite tricky - but very rewarding if you get it right.

At the same time, AMS2's Mosport might not look the part (although maybe a retro version might come - you never know with Reiza), it also fits well on the calendars of three F1 seasons represented in the sim, those being 1967, 1969 and 1974. And somehow, I have a feeling that any of the 1990s IndyCars, called F-USA in the sim, might be a very good fit for the circuit as well.

Of course, you do not have to stick to AMS2 for your dose of Mosport. There are multiple mod versions available for Assetto Corsa in our download section, for instance, and there is an rFactor 2 version as well - although that is nine years old at this point, so your mileage may vary. Older sims like the original rFactor or the first Automobilista also have one or more modded Mosports available - and if you really want to go old school, look no further than Grand Prix Legends, which has the track by default.

What do you think of Mosport? Have you tried it before, and is it even maybe a favorite of yours? Let us know in the comments below!

Speaking of being sold, the track belonged to Lawrence Stroll but I believe he put it up for sale. That's the last I heard about it.
Mosport (CMTP) is not in the middle of nowhere. It's an hour east of Toronto just north of a suburb. It is also never been owned by Stroll. It's a fantastic quick snaking track with great elevation changes. The development course isn't too bad either.
In 2011, Mosport Park was purchased by Canadian Motorsport Ventures Ltd. (CMVL), which was established for that purpose by Carlo Fidani and partners Ron and Lynda Fellows.

Ron Fellows is a Canadian Race Driver and has had a racing career as one of North America’s most versatile and successful road racers. And the car named after him? The Ron Fellows edition Corvette Z06 of 2008, compete with a signature trim package. This Corvette was the first signed special edition in the history of the US sports car, and with only 399 samples produced is a fitting tribute to one of Canada’s top racing ambassadors.

They were referring to Stroll owning Mont Tremblant, not Mosport.
 
I would say 3. Calabogie, of the 3, is my personal favorite. Done track days on the 3 of them, love the experience on the 3 of them.
Mosport is the scarier, Tremblant more majestic but Calabogie is a gem to discover.
It is available in AC.(as is any other Canadian track from coast to coast).
Well, I didn't say "only" 2 excellent road courses.

That said, for me, Calabogie runs into a couple of the main issues I have with Barber, which isn't so surprising, since they're both Alan Wilson tracks. But Calabogie also adds something else to the mix.

Now don't get me wrong, I like Calabogie's setting and the undulating terrain. In general, in observational and cerebral terms, I find the track fairly interesting.

But to start with, Calabogie is more angular and less flowing than Barber, but not to the extent we see with Arizona or Carolina Motorsports Parks. And that can be problematic both with respect to the overall form of the circuit and in terms of raceability. For instance, if you have a kink or bend in the "wrong" place in/ahead of a more serious braking zone/even slower corner, that can foul things up. Calabogie seems to have more than 1 of these, with Sir John A. ahead of Mulligans, Crown/Brow before Beak, 4 Left ahead of Quarry One, and to a lesser degree, Kink before Jacques.

Prominent examples at other circuits include Turn 1 at the Nurburgring GP Circuit before the T2 hairpin and the little kink right there in the braking zone for the Tamburello Chicane at Imola.

As for the commonalities between Calabogie and Barber, they can seem "too busy" like they're designed more for club and/or bike racing than more serious cars. So it's not just the corner density, but the proportion of the corners that are only low- or medium-speed in nature. For being a ~3-mile road course, Calabogie isn't particularly quick, with the Porsche Carrera Cup lap record at just over 90 mph, which is street circuit territory for GT3s (thinking of Long Beach, St. Petersburg, and Nashville).

For a track I perhaps see more favorably in some aspects that I might compare it to, I'd point to Pittsburgh Int'l Race Complex.

Honestly, I didn't care all that much for Barber until after IndyCar introduced the DW12. That's kind of the irony of it, that a track like that can work better, if you have enough downforce to create some longer, high-speed runs out of what's there. Calabogie doesn't have any really long, true straights, either, so you need some fast corners to create longer stretches.

I think, with enough downforce, you could get that into Jacques and Quarry, but that isn't exactly the issue for the run to Mulligans, and I just don't think there's enough space between Crown/Brow and Beak to set up a move there.

Then again, unless the downforce can make a big difference at Quarry/Watt's Up/Wicked and Jacques/Gilles, I don't know that you can see the sort of improvement that occurred at Barber.

If nothing else, I could really use a good race broadcast from Calabogie, like Porsche GT3 Cup, to give a better idea of the racing, and with good external camera angles to show off the track.

@Taruffi before reading your post, I thought I knew Calabogie , your knowledge of tracks is impressive to say the least. I also did not know it has been design by the same track builder as Barber. Thank you for the extensive description.

Echoed my sentiments exactly. Well said :)
 
Glad I could be of help.

And yes, Alan Wilson is behind quite a few circuits in the last few decades. This includes a good number of "club" circuits here domestically, as well as a few int'l efforts, like Ningbo, Chine and Inje, Korea.

The 5 tracks I noted in my last comment, Arizona, Barber, Calabogie, Carolina, and Pitt Race (initially Beaverun), are all Alan Wilson designs. He's also done Miller Motorsports Park and The Thermal Club, along with the refurbishments at Mont Tremblant, to give a few, more high-profile examples.

So yeah, there's quite a range with him. Some of his stuff I quite like (Pitt Race), and other things (Ningbo), not so much. I'll add, IndyCar has been to another Alan Wilson track besides Berber and Thermal: NOLA.

What is Thermal: NOLA?

Makes me think of No Problem Raceway - outside New Orleans.. Interesting experiences there...

Here are the basics of NOLA Motorsports Park:

IndyCar running a modified layout in 2015:

Trans-Am running essentially the original layout in 2024

And then, this is The Thermal Club:

Yes, there are issues of consistency between different sources in terms of trying to figure out the lengths of the different course configurations. For the purposes of my spreadsheets, I list the IndyCar layout as being 3.400 miles around.

The IndyCar exhibition event in 2024 on the Twin Palms Course:

In 2025, IndyCar will have a full championship round at Thermal.
