McLaren MP4/5B high-nose concept
The McLaren high-nose experiment lasted only 10 laps during the summer of 1990, at a time when the F1 world was still trying to understand the unusual new shape of the Tyrrell 019.
McLaren quietly rolled out something unexpected at Monza, it looked wrong at first glance, too tall, too exposed, almost unfinished!
McLaren High-nose experiment
This was the experimental high-nose version of the McLaren MP4/5B, a car that was already good enough to win that years, without radical changes, but even big teams get curious, especially when a rival stumbles onto something that might be the future!
The British team decided to chase that future…
Why McLaren Broke Its Own Philosophy
Their cars were low, and predictable; the MP4/5B followed that exact philosophy, hugging the ground with a tightly packaged aerodynamic profile; then along came the Tyrrell.
McLaren had built its success on precision and control. Their cars were low, clean, and predictable. The MP4/5B followed that exact philosophy, hugging the ground with a tightly packaged aerodynamic profile.
The high-nose concept was not just a visual gimmick, by lifting the nose higher off the ground, engineers could push more air underneath the chassis, feeding the floor and diffuser more efficiently.
In theory; that meant more downforce without increasing drag; which is basically the holy grail in F1 design.
McLaren saw it, they understood it!
But instead of redesigning an entire car mid-season, they tried something quicker, almost surgical, they lifted the nose!
Monza, August 1990: A Quiet Experiment
The test took place at Monza, McLaren evaluated this unusual configuration…
The changes were focused almost entirely on the front end; the nose was raised to roughly 25 centimeters above the ground; and the front wing was mounted much higher than usual.
This created a visible gap underneath the chassis, forming a crude airflow tunnel.
So when you look in the picture, it looks more like a prototype, but at the same time it looks even stranger.
The core of the car remained unchanged, same structure, just a dramatically different nose box and bodywork trying to force a new aero phylosophy onto an old design.
Senna’s 10 Laps That Said Everything
When Ayrton Senna finally climbed into the car on the third day; there was curiosity, both in and out of the garage, and maybe even a bit of hope.
Ten laps later, that hope faded!
Ayrton Senna didn’t need a full race simulation, he didn’t need long runs or detailed data breakdowns, after 10 laps, we never saw that nose mounted in a McLaren car again.
Meanwhile; his teammate, Gerhard Berger continued working mostly with the standard configuration, for three days of testing, which was more promising.
No drama, this wasn’t the future, at least, not like this.
The Real Problem: You Can’t Fake an Aero Concept
On paper, the idea made sense, if it worked for Tyrrell, why not trying…
But Tyrrell front wing was a bit different, the one that was successful, Tyrrell 019 used a curved front wing that dipped down even though the nose was high, this kept the wings close to the ground, where they work best, giving the car its smooth ‘seagull’ shape.
You can clearly see how distinct the Tyrrell 019’s front wing and nose were. Its curved “seagull” shape, designed to keep the wing close to the ground, was very different from McLaren’s high-nose attempt on the MP4/5B. While McLaren tried to replicate the concept, the design philosophies were not the same, and the Tyrrell’s elegant, flowing lines highlight that difference.

The MP4/5B had been designed as a low-nose car from the ground up; its floor, diffuser, and rear-end aero were all tuned for a specific airflow pattern.
By lifting that nose, McLaren disrupted that entire balance!
We believe that the airflow under the car no longer behaved as intended, the diffuser couldn’t extract it properly.
And the famous bat floor concept the car relied on simply wasn’t built to handle this new airflow structure.

A Risk That Didn’t Need Taking
McLaren F1 team didn’t need this to work; they were the dominant team in 1990, the MP4/5B, even without experimental aero, was fast enough to fight for wins every weekend.
So while other teams were forced to gamble, McLaren could afford to be conservative, and that is exactly what they chose.
The high-nose concept was quietly shelved by the British team after Monza test.
No dramatic conclusions or public statements, just a silent return to what already worked.
The Irony of What Came Next
Here is the part that makes this story so fascinating; the idea itself wasn’t wrong.
In fact, it would go on to define F1 design for years, but timing is everything.
McLaren’s version failed because it was incomplete, almost like trying to install a single piece of a puzzle without changing the rest, in F1, this never seemed to work.
When high-nose designs finally became dominant across the grid; they came as part of fully integrated aero packages, not quick retrofits!
Even McLaren eventually embraced more advanced concepts in later cars like the McLaren MP4/6 and McLaren MP4/7A, though by then the competitive landscape had already started shifting.
So… Did McLaren’s High-nose Work?
Normally, if you go back to the pits, and never use it again, the answer is no, and not even close, but that almost misses the point.
This wasn’t a failure in the traditional sense, it was a glimpse into how even the best teams can hesitate at the edge of a breakthrough.
McLaren saw the future; touched it briefly, and then stepped back because the present was already good enough.
And in 1990, that decision paid off, they walked away with both championships.
Still, somewhere in that Monza test session, in those ten quiet laps from Senna, there was a version of F1 trying to be born a little earlier than it should have been, McLaren just wasn’t ready to build the rest of it yet.
