McLaren Golf Series 1 review: a metal-injection-moulded blade for the player who was buying a blade anyway

The logo on the back is the first thing anyone sees: the orange McLaren speedmark, set into polished steel above a honeycomb pattern that looks lifted from a car's underbody. It is a striking object. The question a review has to answer is what is left once you stop looking at it.

The McLaren Golf Series 1 is the car company's debut golf club, a muscle-back blade aimed at better players and tour professionals, and it arrives with more credibility than a licensing exercise usually does. Justin Rose retired his long-serving Miura blades for McLaren irons in April. The question for everyone else is narrower than whether Rose can play them. It is who a blade from a supercar brand is actually for.

Who McLaren Golf is

McLaren Golf was announced in March 2026 and launched its first two irons on 29 April, on sale from 30 April in North America, Europe and South Korea. The chief executive is Neil Howie, who spent more than 25 years in senior roles at Callaway, which tells you this is a golf company wearing a car badge rather than the reverse. Rose, Ian Poulter and Michelle Wie West are ambassadors and, according to launch coverage, investors too.

There are two models. The Series 1 is the blade. The Series 3 is a players-distance iron with carbon fibre elements, and it is the one the brand put first: reporting since launch, including MyGolfSpy's, has the Series 1 arriving months behind its April date, with blade stock landing only at the end of September. That is a sensible commercial order, since blades are a small slice of the iron market, and it is worth knowing if you tried to order in the summer and gave up.

How it is made, which is the interesting part

The Series 1 is not forged. It is made by metal injection moulding, or MIM: a fine metal powder is mixed with a binder, injected into a mould under heat and pressure, and then the binder is removed and the part is sintered into solid steel. McLaren uses a proprietary steel blend and says the process gives it detailed control over material structure, weight distribution and internal geometry. Launch coverage called it a process rarely used at scale in golf because of its complexity and cost. It is not new to golf, Cobra has used MIM in production clubs for years, but it is unusual in a blade.

What MIM buys is the ability to build things inside a head that a forging cannot easily hold. The Series 1 carries internal tungsten weighting, a silicone dampening system for feel, and McLaren's Structural Mesh, the honeycomb pattern on the back, which GOLF.com reports removes around two to three grams from non-critical areas. That saved mass goes to the perimeter for stability and to tune the centre of gravity, which moves progressively from low to high and from heel to toe through the set. Offset steps up through the long irons, by nearly a millimetre between the 8 and 7 and by 1.2mm between the 6 and 5, and the sole is flat to keep shot-shaping options open.

If that sounds familiar, it should. Cobra's 3DP MB is the same idea built a different way, a printed blade that frees mass for tungsten in a shape with nowhere to hide it, and we went through what that does and does not buy in Cobra 3DP MB vs Srixon Z-Forged II. The short version applies here too. If you care about the word on the hosel, what forged actually means is worth five minutes before you decide it matters.

Forgiving for a blade is still a blade

McLaren's pitch is that the Series 1 challenges the idea that blades lack forgiveness. Fair enough, as far as it goes. Moving tungsten and saved mass to the edges of a muscle-back raises its stability compared with a solid block of steel, and a progressive CG should make the long irons easier to launch than a traditional set.

But be clear about the scale of that. The lofts are classic blade lofts: 34 degrees in the 7-iron, 46 in the pitching wedge. There is no distance engine, no hollow body and no wide sole. A strike off the toe will still come up short and feel like it. The forgiveness claim is relative to other blades, and the relative bit is doing the heavy lifting, exactly as it was with the Cobra.

Rose's own set says the same thing. Launch coverage described him blending the two models, Series 3 in the longer irons and Series 1 below, which is the combo set nearly every tour player with a blade ends up building. If a 45-year-old major champion wants help at the top of the set, so do you. His current bag is on Justin Rose's WITB.

The price is per head

McLaren sells the Series 1 one club at a time, from the 3-iron to the pitching wedge, at the same per-head price as the Series 3. A standard 4-to-PW set is seven heads, so this is a four-figure purchase before you choose a premium shaft. The good news is that it is sold the right way: through select custom-fitting accounts (in the US that includes Club Champion and True Spec) and direct, with loft and lie adjustable by two degrees either way and length by an inch and a half.

The thing the price does not include is history. A debut brand has no track record on how the finish wears, how quickly replacement heads arrive, or what the irons are worth in three years. None of that is a reason not to buy. It is a reason to buy only once you have hit them against what you already own.

Who it is for, and who should skip it

Buy the Series 1 if you are a low-handicap player who strikes it from the middle, you were going to buy a blade anyway, and after a fitting you prefer how this one looks, sounds and flies. In that case the engineering is real, the build is serious and the badge is a bonus rather than the reason. I would also understand the buyer who simply loves the object. That is a legitimate reason to spend money, as long as you know that is what you are buying.

If you want a traditional forged muscle-back with nothing clever inside it, the Srixon Z-Forged II is soft 1020 carbon steel, a compact shape and a set price from an established iron maker.

And if you are above single figures, skip blades altogether, McLaren's included. The Ping i240 gives you a players' look with a real margin for error underneath, and that margin is worth more to your scores than any amount of tungsten in a muscle-back. We made that case at length in you're not good enough for blades.

The verdict

The Series 1 is a better debut than the cynic in me expected. It is a thought-through blade built by people who have made irons before, using a manufacturing process that does something specific, and it is sold through fitters rather than off a showroom shelf.

It is also a blade, and a blade suits a small group of golfers no matter whose name is on the back. If you are in that group, it deserves a place in your fitting. If you are not, the most expensive mistake you can make here is letting a car brand talk you into the hardest irons in golf. The wider field is in our irons and wedges guide.
