Could our BMW 435i outrun a Supra for half the price?

When we take our project cars to the test track, we’re not immune to comparing them to the larger leaderboard ourselves. It’s nice to know that we could build a 2017 VW Golf GTI that could run toe-to-toe with a late-model Golf R, for example, or that our Club Spec Mustang, even in undeveloped form, could run with the rather quick Hyundai Elantra N.

Our BMW 435i project regularly bettered the current Toyota Supra at the Florida International Rally & Motorsport Park. Both cars are BMW-based, front-engine, rear-drive coupes with very similar suspension designs and probably even a few shared part numbers.

But our 435i is powered by the far less sporty N55 engine, producing a rated 301 horsepower, while the Supra rolls with a more modern B58 3.0-liter rated at 382.

Now, knowing BMW, we assume that both of those numbers are probably conservative, but even spotting them a few percent, the N55 is at a serious disadvantage–and that’s before you realize it’s also carrying an extra 200 pounds and has a longer wheelbase.

Of course, our BMW has been prepped and tuned to a fairly high level, with some extra power thanks to a digital tune from MHD and a CSF intercooler. A set of 10.5-inch-wide BimmerWorld TA5R wheels hold sticky Vitour P1 rubber. MCS dampers, Powerflex bushings, 034Motorsport anti-roll bars and Hawk brake pads all help as well. Also add in all the fancy internal engine reliability and oil system work courtesy of BimmerWorld.

Our setup, including the car, could be duplicated for well under $30,000–and probably even less thanks to the recent downturn in F3X BMW prices.

The Supra? We checked prices.

A couple of dealers in Florida are advertising 2026 Final Edition Supras like our test car–which gives you slightly larger front brakes as the only actual performance upgrade over any other Supra–for at least $73,961. One was a Burnout White example with the eight-speed auto at Toyota of Tampa Bay. For that money, you could build two clones of our 435i and have enough left over for a nice NC Miata and groceries for a couple weeks.

We figured our BMW 435i would run about a second back–not bad for, depending on your math, about half the price. Circuit Florida puts a bit more of a premium on power for lap time than the FIRM.

The BMW should have an edge in handling, we figured, due to stickier tires and a more track-tuned suspension. But the Supra’s 80-plus-horsepower advantage–even with our spiciest tune that puts about 316 to the wheels–was insurmountable.

The result, however, was a virtual dead heat. According to the VBox data, our BMW ran within a tenth of a second of the Supra: 1:28.34 for our 435i (blue trace) versus 1:28.26 for the Supra (red trace).

A glitch with timing?

We run a second VBox system as a backup that had both cars in a tie to the hundredth of a second.

So how did our lower-powered, heavier BMW manage to run heads up with a car a quarter again more powerful, 200 pounds lighter and more than 10 years newer? Was the handling bump enough to overcome the substantial power deficit? Let’s take a close look at those Circuit Florida laps on the VBox data and find out.

First, an asterisk. At Circuit Florida, we have been measuring times from a location that is not the start/finish line the track typically uses for its in-house lapping activities.

We measure from a spot on the Amazon straight (so named because it runs next to an Amazon warehouse) since it provides several good visual and GPS references to sync to for video, data and timing.

It also allows us to start a flyer sooner, saving wear and tear on media loan cars. So it’s as much a production and logistics choice as a competitive one.

That said, if we had been measuring from the actual Circuit Florida start/finish line, our 435i beat the Supra by a couple tenths. But let’s base our discussion on the best laps from our start/finish, since that’s what will be relevant in the future as we gather even more test data there.

First, the Supra still has a clear advantage in the straights, even though our 435i has the spiciest tune we can manage from the MHD software. That power bump is good enough for a 5 mph advantage to the Toyota at the end of the Amazon straight, along with a 3 mph advantage at the end of the next short straight. It adds up to a more than half-second lead for the Supra barely a quarter of the way into the lap.

Then the turns come.

Through the middle section of the track, with its quick right/left/left/left combo, the BMW picks up 0.6 second over barely 1400 feet of track, taking a 0.1-second lead over the Supra by the exit of the wiggles.

The Supra immediately claws back to a tie down the next short straight, but then immediately gives it back through the fast left-hand kink and the tight right-hand bend at the end of the straight. At the end of those twisties, the BMW has racked up a nearly 0.4-second lead.

The Supra takes the deficit all back down the long final straight, but gains no real advantage by the end of that fastest section into the final twisty bits. Through those sections, the cars are neck and neck, with the BMW pulling out a slight gap in corners and the Toyota using what it can of the short chutes in between to put power down and stay close on the clock.

By the time the finish arrives, the Supra uses a final burst of superior thrust to pull even with the BMW, which had eked out a 0.3-second lead through those late twisties.

So yes, the 435i did absolutely have enough handling to just make up for the power deficit.

On a longer track with longer acceleration zones, the Supra probably runs away a little more. On a twistier circuit, the BMW might have a clearer edge–well, until you put some camber and 200tw tires on the Supra.

Still, for this budget-friendly, daily drivable BMW to run heads up with its own ultimate form for a fraction of the cost is pretty impressive. Both cars are enormously drivable, but the 435i on sticky tires is downright magical. You’d never know it was a 3600-pound car from the way it transitions with such authority and lets you make adjustments mid-corner.

And this is a car with a low-revving, torquey engine restricted by its tiny turbocharger that I routinely shift at 6000 rpm since that’s where it gets the best acceleration. The Supra is a fire-breathing beast that spins north of 7000 and makes power every inch of the way.

Obviously the Supra has the higher ceiling once you start throwing mods at it, but for under 40% of the cost, our chubby little white BMW has some amazing track manners and capabilities, and it still drives like a dream every day.
