Motor Trend comparison test..........
Saw where Motor Trend just did a comparison test of roadsters and per usual the Boxster S had everyone giddy. Z4 35i got a pretty lousy review based on the ride quality mainly. I think we all get that the Boxster is a pure sports car and probably has no real equal. Not to mention it weighs 400 lbs less than the Z4! It would have been prudent, however, to wait until a 35is was available imho. I looked at the performance data and they got 0-60 in 4.7, .92g of grip and 102 ft 60-0 for the Z4. Not too bad, but anyone have a guess as to what the numbers may look like with the 35is? I will be very surprised if 0-60 time is over 4.5 sec, and the skid pad and braking numbers should be a little better as well.
As always it comes down to personal taste and wants/needs. I like the way the Z4 looks and in the real world the performance will be plenty good. I had a 2000 M Roadster and it was a blast to drive even with the dated suspension. |

they also didnt test one with the dct, which makes the z4 a blast to drive. They didnt seem to like the standard shift in the z4. The z4 is not a true sports car, its a roadster which is great for top down cruising and I find it great in the twisties and it has a very pleasant wonderful ride that Clarkson said, "if you could only have one car for the rest of your life, then he would be happy with the z4" I pretty much agree with that. I took out a boxter s before I bought this, and I much preferred the hardtop convertible. I liked the fact it had that small window that allowed me to shoulder check easier and it felt much less claustrophic compared to the boxster, and I especially much preferred the interior of the z4. The exterior, there was no contest. The boxster only looked good to me from the back. The z4 is a classic in design.

I seem to think that the running costs (hugely expensive spare parts/servicing costs) for a Porsche are in a different league to BMW....well they are here in the UK

Both of the two previous post highlight the true differences.
The Z4 is a Grand Tourer, a classy (and classic) looking car that's comfortable, fun to drive in real-life situation, with performance that exceed what most roads can support yet is right at home pulling over at the valet parking spot at a fancy restaurant or a black tie affair. The Boxster S is a true sports car that's at home on the track but is only a so-so daily driver unless one spends tons of money on comfort options (and then one mights as well spend it on a 911 convertible.) In the U.S. in particular, the Boxster will never be driven at the limits on public roads. Oh, and Porsche maintenance is expensive anywhere! There is no right answer, it's a continuum, one just needs to find where their comfort spot is: Lexus SC <--> Mercedes SLK <--> BMW Z4 <--> Porsche Boxster

I moved from E85 to E89, and yes the Z4 has gone softer, but my limits as a driver are exceeded long before the car starts to struggle. I don't intend to drive it on track, didn't do that with the E85 either. Haven't read the Motor Trend article, because I simply don't see the point. But if they didn't like the manual gear box, they have zero credibility in my eyes. As far as manual boxes go, I think it's pretty much spot on. |

My last car had an excellent manumatic with paddles, but nothing replaces manual for driving pleasure. So I can't shift in 10 milliseconds, but that's not the point. If one wants a truly quick track car, then a Cayman or 135i Coupe with DCT is the way to go (or a Lotus) Why have the added weight of a convertible? If ones wants hair-in-the-wind old fashioned touring fun with a capable but simple and predictable chassis, then the Z4 manual is the one. Which is why I bought one.

The 35i with DCT ran the 0-60 in 4.3 seconds when MT did their Car of the Year comparison. So, the 35is should run about a 4.1 - 4.2.
By definition, The Z4 is a sports car, not a Grand Tourer. The term Sports Car has been defined as "an open, low-built, fast motor car. The term describes a class of automobile with two seats, two doors, precise handling, brisk acceleration, and sharp braking — trading practical considerations such as passenger space, comfort, and cargo capacity — for driving enjoyment. The term Grand Tourer (Italian: gran turismo) (GT) is a high-performance luxury automobile designed for long-distance driving. The format is a two-door coupé with either a two-seat or a 2+2 arrangement. When I hit the ignition key, and drive off, I am driving a Sports Car that hits 60 in 4.3 seconds, as documented.

I already said this in another topic (I think) : I drove both the Boxster and Z4 before deciding which one to buy : the boxster is indeed more pure a sportscar than the Z4, but it is more noisy, costs (a lot) more, maintenance will be more expensive, .... (but it will probably keep it's value better than the Z). I decided to buy the 35iS
Here some numbers of the 35iS version, tested in Europe: 0-100km/h : 4,8s (as advertised) as opposed to 35i 5,2s 0-200km/h : 18,0s as opposed to 35i 19,4s 80-120 (highest gear being 7th in this case) : 6,8s as opposed 35i 7,8s (!) -- same exercise in 4th gear takes 3,8s Fuel consumption: 12,8Liters (minimum : 7,9L -- maximum : 15,5L) Braking distance from 100km/h : 35m (cold), 36m (warm) Braking distance from 190km/u : 137m

today, was a gorgeous sunny day. I put the top down,, looked at the beautiful black saphire paint glisten. Drove away with that lovely sound coming out the exhaust. Pulled up to a light and three women in the car next to me, stared and the driver said, that is one beautiful car. She said, "its just stunning". I smiled and slowly moved on, basking in the sun and enjoying the day. This car is wonderful, plain and simple.

The only documented figures i've seen is 5,1 sec 0-60. Whatever figure is right it's more than enough between the redlights. Last edited by SHADOW4; 04-21-2010 at 06:25 AM.. |

2010 BMW Z4 MT "The 35i is a stormer: 0 to 60 takes just 4.3 seconds. Few automakers do chassis like BMW, and the Z4’s doesn’t disappoint. “Great grip, largely neutral handling, stability intervention minimal in Sport+ mode,” notes technical director Frank Markus. The 35i needs just 107 feet to stop from 60 mph." "Engineers took advantage of the new roadster's 15-percent improvement in chassis stiffness versus the previous model. The suspension doesn't skitter over bumps as easily. Drive it on anything but the most potholed streets, though, and you'll want to engage the Sport setting, if for no other reason than its quicker steering, which is already among the most direct you'll find in a sports car, belying its electromechanical roots. The Sport setting's springs, shocks and dampers are calibrated to match the last Z4's, but with better suspension travel.For good mountain roads, Sport+ stiffens things up further, making it a sharp-edged sportster. Turn off the stability control in this setting and you can dive for second- or third-gear corners with very little body roll and exit with just the slightest bit of oversteer as the rear tires slide out a bit. The steering feel and directness makes for a nice partner in shussing the esses." C&D "The chassis is well balanced, and the body motions are always controlled. Handling is predictable, which makes the Z4 feel lively at low speeds and inspires confidence as the pace quickens. The steering is well weighted and direct. The Z4 moves sharply along twisty roads, but the steering feel and the extreme rearward driving position make for a personality that is more deliberate than darty." "The Z4 keeps a flat cornering attitude in all three settings, and the neutral handling gives way progressively to gentle understeer at the limit. " R&T "Handling on mountain roads (or the all-important entrance ramp GP) feels sure-footed and predictable, and the car's supple suspension and excellent ride quality keep the Bridgestone Potenzas connected on bumpy curves. Ultimately, with Dynamic Stability Control turned (mostly) off, the Z4 can be made to oversteer in the slalom and skidpad, but it stays gathered up and easy to drive at normal fast road speeds."

IMHO, if you are an inexperienced racer or just getting into sports car, go with Porsche for precise handling that will help you. If you are more experienced and enjoy pushing a sports car to the limits and can skillfully handle it, then go for the Z4.
both cars are fun either way. Big aesthetic difference!

To sum it up: It's fastand yet, It has a supple suspension and excellent ride quality. Ahh. . . .memphis2012, don't mean to contradict. . .but where's the contradiction? It all sounds pretty good to me. . Last edited by teagueAMX; 04-20-2010 at 10:35 PM.. |

Geez. Timed track events in identical cars always produce a spread in the standings. The biggest variable: who's driving and how well they did on that particular run. So it gets down to what you plan to do with the car. Track it a lot? Maybe the Boxster is for you. Actually drive it in the real world? Z4 is more tractable and pleasant. And when you pile on maintenance costs and side-by-side options, the Porsche really starts to look like a pricy toy.
Toys are good. The Boxster is a good tech toy. The Z4 is a really nice toy. Really nice. |
