Magnum MK5 Public Debut and We Talk with Bruno St-Jacques

Magnum MK5 1

You may remember back in November, we told you about a new track-day monster called Magnum MK5.  You may also remember that it hails from Canada.  I know what you’re thinking, and yes, Canada does have more than just hockey and curling.  The little speed demon has just made its public debut at the Boca Raton Concours d’Elegance duPont Registry Live Hangar Party shin-dig.  We were there to get up close and personal with the MK5 and have a chat with Bruno St-Jacques, the Magnum MK5’s creator.


To refresh your memory, the Magnum MK5 has pretty stellar performance.  It’s powered by a 250-horse four-cylinder from a Hayabusa motorcycle with 11,000 rpm “screamin’ at you” and routing power to the rear wheels via a six-speed sequential manual gearbox.  The 1,200 pound car runs from 0 to 60 mph in 3 seconds (0-62 in 3.2 seconds), tops out at 150 mph and can pull an astonishing 2g+ in the corners.

That is all as it should be, considering the brand’s pedigree.  Bruno St-Jacques’ father Jean-Pierre St-Jacques founded Magnum to build Formula race cars for racing legends like fellow Canadian Gilles Villeneuve.  Bruno, a successful race car driver himself in the Formula Atlantic, International Formula 3000 and Rolex Sport Prototypes series, wanted to create a race car for the street using the knowledge gained from a lifetime around very, very fast cars.  And, boy did he ever.


During the public debut in Boca, I asked Bruno St-Jacques what made him decide to develop the Magnum MK5.  His answer was a simple one…  Throughout his life, first watching his father develop formula cars through to his own racing career, he “always had that idea of building a modern-day Magnum.  And, this is it.”  I can’t imagine a better genesis for a fast car than that.

When asked what his inspiration was for the Magnum MK5, St-Jacques replied “there was no inspiration in particular.  I’ve loved cars forever, and I’ve seen lots of cars and concept cars when I was younger and growing up.  I guess this is just what I had in mind as the perfect concept car…. We wanted something very clean… aggressive but clean.  Not too much bulkiness and stuff… clean lines…  It’s more like a lightweight supercar than just a track-day car.”


Seeing this car up close, it is hard to argue.  There isn’t much there in terms of creature comfort, but there really doesn’t need to be.  This is a two [carbon fiber bucket racing] seat car with just one purpose… to go extremely fast in a straight line and even faster around corners.

The Magnum MK5 officially goes on sale this month for a starting price of about $155,000.  A dealership network will be rolled out soon to handle the sales of this fastest of Canadian cars.  I can tell you that the Magnum MK5 is stunning and rather badass looking in person.  I just hope I’ll have an opportunity to give it a whirl myself.  For more information, visit and check out the tech and performance specs below.
