Golf clubs and cars. Not much in common except you use a car’s trunk to transport golf clubs to the course, right? Not so fast…

Ignoring the obvious size and price differences, the two things do have similarities, and more than they can both technically “drive.” Cars and golf clubs are designed to be aerodynamic, and for that reason we see similarities in their styling. After all, engineers have similar tasks with high-performance cars and clubs, notably, making them faster and more efficient. That’s why we hear many of the same trigger words in both worlds, including MOI (moment of inertia), a measure of twisting and turning, and CG (center of gravity), a measure of weight distribution in relation to the center of mass.

It’s only right, therefore, that car companies and golf club companies align themselves in the marketplace, even if it’s just for one-off products. Below, I take a look at golf clubs that were inspired by or made in collaboration with the auto industry.

Bentley gets into golf clubs

Bentley Golf stopped us in our tracks at the 2016 PGA Merchandise Show in January, where myself and others took the time to drool over the Bentley on the show floor, and look at this… Bentley-inspired clubs!

While you can get a set for around $2,000, the full custom fitting experience, which includes custom shafts made just for you, will run you about $100,000. That’s a lot of zeroes. Would you rather own the car or the clubs? If you’re thinking about your budget, then neither are for you. See more Bentley Golf photos here.

Ferrari and Cobra

Before Callaway’s drivers were made with input from Boeing, these limited-edition Cobra drivers were made with input from Ferrari’s aerodynamic experts. And as you’d expect, the influence of the Italian supercar brand drove the price of a driver to $2,000, roughly five times as much as the average Cobra driver at the time.

The Ferrari driver was designed using the Cobra ZL driver platform, and came equipped with a Ti 6-4 face with carbon fiber on the crown and sole, according to Golf.com. It was said to produce 1-3 mph more ball speed than the ZL, but never made its way to the PGA Tour, although Ferrari fanatic Ian Poulter tested it extensively.

Cobra’s Ferrari driver was released along with a collection of putters, hats, jackets, shirts and other overpriced items.

Mercedes AMG golf clubs

Before Bentley Golf drove onto the floor at the 2016 PGAM Show, Mercedes Benz rolled out a line of golf equipment at the show in 2012.

WSH Inc. acquired permissions to use the Mercedes Benz logo in its production of the line, which included drivers, woods, irons, wedges and putters. The drivers ($399) and woods were made in conjunction with aerodynamics specialists at the company, and employed “Venturi Channels” used to “to manipulate airflow whereby a funnel is created as air flows through the vehicle, and is constricted, and as it flows out…a jet effect is created,” according to an article from Golf Digest.

Callaway and Lamborghini 

Lamborghini and Callaway combined forces in 2010 and developed a high-strength, lightweight material called “Forged Composite” that was used in both Lamborghini’s cars and Callaway’s drivers. The collaboration yielded the Callaway RAZR Hawk and Diablo Octane drivers, which boasted a lower CG thanks to the lighter material.

Callaway continues to use its Forged Composite construction to this day, although its new XR 16 Sub Zero driver debuted a new composite construction called “Carbon Triax” that the company says is lighter.

Kinsler races into putters

Kinsler Fuel Injection is a company that makes engine parts for race cars. James Kinsler, son of the company founder, used his mechanical engineering expertise and love of golf to start a golf company called Kinsler putters.

Its first run of putters feature a strong visual influence from the automotive industry, as you’d expect, with its curves and anodized finish. The alignment slot has an uncanny resemblance to a hot wheels track, as well. Read more about Kinsler’s putters here.

A Grand Theft Auto golf club?

I know, this isn’t inspired by an actual automobile. But this 5-iron designed after the Grand Theft Auto V video game — which featured a fictional “Los Santos Golf Club” — is pretty cool. The club can currently be found on eBay for around $250.

Willie Nelson’s Rolls Royce Golf Cart 

OK, it’s technically not a golf club, but I wanted it on the list. Country music star Willie Nelson once had his 1981 Rolls Royce replica Golf Cart seized by the IRS, and it was auctioned in 2012 for about $4,200. The cart had a mini bar, radio, head lights, turn signals and of course, the iconic look of a Rolls Royce. It now sits in the Kingman Museum on Route 66 in Arizona.
