Pros: Both models offer a high level of forgiveness across the face and impressive ball speeds. The custom shaft options in the Bio Cell + driver are awesome.

Cons: The aggressive color scheme isn’t for everyone, and the stock shaft options in the Bio Cell isn’t up to par.

Bottom Line: Two exceptionally high quality drivers that offer adjustability, custom color options, big forgiveness and high launch/low spin performance.


The driver is still the sexiest club in the bag, and Cobra isn’t afraid to proclaim this with five bold colors and a gaudy list of technological improvements. That said, in today’s marketplace, if style isn’t equaled or exceeded by substance, you have a problem. Cobra, however, doesn’t have this issue.

The engineers at Cobra have taken AMP (Advanced Material Placement) to a new level utilizing what they call “BiO Cells” to redistribute more discretionary weight from the crown, placing it lower and deeper in the head. This translates into higher launch, lower spin and more distance.

In addition, the modified E9 forged face now offers a more robust sweet zone, improving ball speeds for drives hit low and on the heel and high and on the toe.


The proprietary MyFly8 system allows the player to select one of eight settings to dial in desired trajectory and shot shape, and Cobra’s Smartpad feature supports the club at address and permits the head to sit relatively square regardless of selected MyFly8 setting.

For 2014 Cobra is offering two Bio Cell models, the standard Bio Cell and the Bio Cell +, each of which is available in five colors: blue, black, silver, orange and red. The salient differences between the two models are as follows:

BiO Cell +


The Bio Cell + driver ($399) incorporates T.O.P. (Thin, Optomized, Personalized) technology via use of ultralight Venollum alloy in the crown. The creates a different cosmetic look at address, but more importantly redistributes even more weight to achieve a lower spinning, neutral bias, mid-trajectory 440cc head. The MyFly8 system allows for eight settings with lofts from 8 degrees to 11 degrees. The stock length for the BiO Cell + is 45.25 inches and it has a swingweight of D5. The stock shaft options for each driver include the Matrix 6Q3 Red Tie, Mitsubishi Rayon’s Diamana D+ 72 and True Temper’s Project X PXv Tour 52.

Bio Cell


The standard BiO Cell ($299) is a more draw-biased, 460cc head that is slightly higher launching and higher spinning the the BiO Cell +. The MyFly8 system again offers eight different settings with a loft range of 9 degrees to 12 degrees. The crown is a solid color and the head is made entirely of titanium. The stock length in the BiO Cell is 45.75 inches and swingweight is D3 to D4.5. The stock shaft is Graffaloy’s Project X PXv, which weighs about 60 grams.


Don’t let the bright lights and flashy looks fool you. These are two serious drivers. During launch monitor testing, both the BiO Cell and BiO Cell+ exhibited extremely high and consistent ball speeds. As advertised, drives hit low on the heel and high on the toe were not punished nearly as much as one would expect. Ball speeds dropped by 1-to-3 mph on average and dispersion stayed very consistent. Given the competitive nature of the driver marketplace, the E9 face offers the consumer a very nice value added feature!


With the standard Bio Cell, trajectory was noticeably higher and the ball consistently wanted to draw. I was able to get the spin to a very reasonable level (2700 RPM) at a loft of 9 degrees. The stock shaft held up very nicely and will fit the vast majority of players quite well. That said, the more I went after this driver, the stock shaft seemed to have a speed limit somewhere north of 105 mph. If you’re torn between the Bio Cell and Bio Cell +, you’d be remiss if you didn’t try a variety of shafts in both heads as I’m not convinced the stock shaft in the standard BiO Cell is a great fit for players with a higher swing speed, a mid-to-late release and those who place a medium-to-significant load on the shaft.

Essentially, the Bio Cell is aimed at the player who wants a higher ball flight and needs moderate spin for optimal distance. I would love to see how this head performs with a premium, low-spin shaft as the head itself is hot, forgiving and gives a slightly higher trajectory, which will benefit a lot of players.

As for the BiO Cell +, this driver just absolutely killed it! Even at 440cc, the E9 face was uber forgiving and it was easy to work the ball right-to-left and left-to-right. The ball flight was medium high, but it never ballooned and spin was consistently in the low 2000s. Combine that with ball speeds in the low 160s and you have a medium launch, low spin monster that was as hot, deep and forgiving as anything on the market. This head was tested with the Matrix 6Q3 Red Tie shaft in stiff flex, which was a bit light and loose when I really went after it, but the free upgrade of a Diamana D+ 72 would easily have solved that issue.


While other companies are pushing the low, forward center of gravity concept, Cobra is very comfortable with the low, neutral CG concept. Given the performance of the BiO Cell line, their position makes an awful lot of sense.

Looks and Feel

This isn’t the club for the self-conscious golfer. In fact, this is the club for the golfer who is maybe a bit attention deprived and doesn’t mind standing out for something other than his or her silky smooth range swing.  Traditionalists will decry the loud colors, but after they’re done yelling at kids to get off their lawn and turn down their rock music, they might actually come around. I certainly did. At first, the color wasn’t my favorite feature, but it started to grow on me. In fact, I found the graphics on the BiO Cell+ to frame the ball a bit better at address, but others may like the more consistent and solid single color of the standard BiO Cell line.

Cobra’s Venollum alloy is made of magnesium, aluminum, zinc, copper and zirconium. It’s welded into the crown of the Bio Cell + driver, and is 4.1 grams lighter than the 6-4 titanium alloy used in the the Bio Cell for a low, deep center of gravity that launches the ball with slightly less spin. 

In terms of feel, the best way I can describe it is substantial and solid. Some clubs feel hollow and loud, while others feel void and dead. The Bio Cell line sits comfortably in between these extremes.

This might be a bit picky, but if the primary purpose of a headcover is to protect the club, then it shouldn’t have holes. I’m not entirely sure what the purpose is of this feature, but for all of the exceptional design features present in the club, the headcover is a let down.

The Takeaway

Cobra’s Bio Cell and Bio Cell + drivers are solid. Rock solid.


Cobra isn’t the first name often mentioned in conversation regarding premier drivers, but it’s not for lack of quality or performance. These drivers are sleepers and some simply won’t give them a go because of their aesthetics. For those who do, they might be surprised at the results.

Critics will point out the low, neutral center of gravity strategy is soooo 2013. But you can’t argue with results, and this club has that in spades. The Bio Cell and Bio Cell+ drivers sparkle and do not fade… that is, unless you want them to.

I didn't grow up playing golf. I wasn't that lucky. But somehow the game found me and I've been smitten ever since. Like many of you, I'm a bit enthusiastic for all things golf and have a spouse which finds this "enthusiasm" borderline ridiculous. I've been told golf requires someone who strives for perfection, but realizes the futility of this approach. You have to love the journey more than the result and relish in frustration and imperfection. As a teacher and coach, I spend my days working with amazing middle school and high school student athletes teaching them to think, dream and hope. And just when they start to feel really good about themselves, I hand them a golf club!

  1. Bio Cell + – another great Cobra driver. Like the look – performs well. Most drivers are for me are in the same range of 220 to 250. Cobra is comfortable and inspires confidence.

  2. Just bought the Bio Cell today, and they let me hit a hundred balls to try it out. Man this Baby was a sure buy for me. I have never ever hit so many high straight shots in my life. I was blown away to say the least. My wife bought the ladies and she was shocked at her drives. We are So glad we bought these and now we have the whole set of Baffler Irons which we love as well. Thanks Cobra for making a Great driver that will improve our game and make playing fun again. LOVE this Driver !!!!!

  3. Yeah , agree with you MH. 108 mph clubhead speed equates to 162 mph ballspeed . Multiply that by 1.5 = 243m carry plus rollout of 12m carry = 255m
    255 x 1.1 = 280 yards at sealevel

      • The head covers are fine as is. I played all of 2014 with a Cobra driver and 3 wood with these head covers and did not get one scratch or rub on either because of this feature. I’m not entirely sure why they did this (the moisture idea above is probably most likely), but its definitely not a drawback at all.
        I think with Cobra’s style and tendency to break from the norm, these are just an extension of that idea.

  4. My spin was 3500 with the stock made for pxv, I had to buy a shaft at an up charge without trying which I hate doing. But it works well.

    Can you post a pic of the Headcover because mine has no holes in it, although it is a poor fit.

  5. I was fitted for the BiO Cell + with the 6Q3 Red Tie in Stiff. This club is a monster. My swing speed is around 107-108 mph, and I was noticing pretty consistent and excellent results. Spin was right around 26-2700, and I’m getting around 265-275 total with 245-255 carry. I naturally get lower ball flight and a fade, so I play the driver at the 10.5 Draw setting, and it works wonders. This driver gives me 20-30 yards more (on average) than the RBZ 2 I had previously.

    • That’s way too much spin for your swing speed, most guys swinging at your speed with efficient launch and spin rates are bombing it past 300 yards total with a straight ball. You’re wasting effort swinging that fast with that much slice and under spin. Time to change your swing

      • I don’t think most guys or even any guys are bombing it past 300 with a 108 club head speed. I would say about 280 would be tops for that swing speed in less your counting on a whole hell of a lot of roll. Last time I was seriously on a launch monitor it gave me a 305 avg on 112 club head speed and was figuring in 25yds on the ground. Which I will say is more than I see in real life but I know launch monitors are assuming optimum conditions.
