One fast two-ton German

When BMW introduced the new E39-chassis 5-series sedan for 1997, I wanted one. Specifically a 540i with the big, 4.4 liter V8. I'd seen one on TV that did such a ferocious burnout, it left a pile of smoking rubber at the start line.

And then I saw my first E39 M5 in 1999. It was Imola Red, with those signature graphite grey wheels, and it rumbled into the parking spot next to me. It was low. It was wide. It looked like it had just eaten a Miata for breakfast and, like a distended snake that had just swallowed its prey, was in the process of digesting it and would eventually spit out the spare parts.

But it was amazingly expensive, and completely out of my price range, so I spent the next 13 years drooling over them. Even though BMW introduced two revisions of the M5 since, they never spoke to me like the 1998-2003 models did.

One day recently, I got a call from a fan of this blog. "I have a 2003 M5 that I want you to drive." I'm in.

It turns out that Mike is a local, and has owned some really cool cars over the years including a modified Porsche 928, a track-only Miata, and a screaming-yellow Honda S2000. Mike and I are close in age and, like me, has always had an affection for the E39 M5 but could never afford one when new. All that changed when he came across a well-maintained dark silver 2003 M5, and sold the S2000 to help make the deal."I still miss the convertible top, but the driving experience of the BMW makes up for it," he says.

So on a clear, warm Saturday morning, I'm sitting outside with a cup of coffee when I hear some wicked muscle car coming up the street at high velocity. It doesn't sound like the typical guy in a Camaro or hopped-up pickup truck. No, it's Mike and his Sterling Grey Metallic M5 cresting the hill up the street at the top of 2nd gear. The car burbles to a low rumble, and pulls into the driveway.

Within minutes, I'm sitting in the driver's seat making adjustments for comfort and visibility. I give a glance to the interior, which is enormous, roomy and very comfortable, when it hits me: this car weighs more than two tons. 4,024lbs, in fact, not including the two people inside.

Being a fan of lightweight cars, I couldn't shake the fact that there was a good chance this car was going to be a big disappointment. After all, it's a looker, but it's also a big, heavy sedan. However the 4.9-liter, 4-cam V8 sounded great through the modified exhaust, and there was a six-speed manual transmission waiting for me, so I kept an open mind. Which is a good thing.

The thing is, this car is easy. The revised steering ratio and suspension bits mean this car will dance through back roads, and the dampeners soak up road imperfections and make the entire chassis feel light on its feet. For the poser who's driving it around town, it's firm. But to the owner who loves driving, it's balanced beautifully for such a large machine.

Although the engine is rated at 396hp, the four cams, individual throttle bodies, and 11.1 compression mean this engine comes up to speed with amazing immediacy. BMW claims this car will do 0-60 in quite a bit under five seconds, and there's no doubt in your mind (or your right foot) that you and the car just covered that bet. Like the suspension, the perception of performance is much different than reality. The car accelerates faster than many "fast" cars, but does it in such a refined way that it doesn't feel hurried or ferocious. You just put your foot down, and the car responds effortlessly and in a controlled manner.

Out on the highway, you really start to notice that the M5 is designed for high-speed travel on something like the Autobahn. Cruise control becomes a welcome ally, because if you don't pay attention to your gauges, you'll find yourself at a comfortable cruising speed that is well above the speed limit. Without much more than a revised front air dam and a tiny lip spoiler on the trunk (along with a lowered ride height over the 540i), the car just hunkers down and will probably happily stay that way up to its computer-controlled top speed of 155mph.

The transmission shifts smoothly, and the gear ratios are spaced very closely together. Aiding in acceleration is the 3.15 rear end, but paired with the big, thirsty V8, this isn't a great car for gas mileage. A great addition would be a super-tall 6th gear (like in the Corvette) for cruising speeds, but the costs for modifications to the transmission would most likely be very prohibitive.

One surprising feature that was a bit of disappointment was the "Sport" feature. Engaging this means revised throttle response, among other things, that go somewhat unnoticed. So if you ever drive one without the feature turned on, you won't be missing much. I also wasn't a big fan of the gauges, which were a mass of numbers that take a while to get acclimated to.

Overall, however, this was one of the most complete cars I've driven. The balance of performance, comfort, and style continue to stand out in my mind, and none seems particularly compromised to benefit the others. If anything, I'd be interested to see how this drivetrain works in a lighter package, like the V8 BMW M3 or the Z8 roadster.

At the end of the day, Mike pulled out of the driveway, and ran it through a few gears for me. The exhaust gloriously rumbled through acceleration, and crackled between gears. My wife turned to me and said, "It's too loud."

No, Honey. It's just right.

Le Mans 2011

If you love the 24 Hours of Le Mans like I do, then this weekend is a big one for you. Friends know not to call during the (somewhat spotty) broadcasts on SPEED channel, my wife knows I won't be mowing the lawn until the race is unceremoniously pre-empted by NASCAR practice laps, and I'll be shopping for enough snacks and carbohydrates to keep me fueled for at least 20 of LeMans' 24 hours.

As the saying goes, "You can't tell the horses without a program," so every year, I like to give a little bit of a background on the race - who to watch, what to look for, and some personal opinions and observations thrown in for color.

So what should you look for? Check out the class listings below. We'll even do a race recap on Monday, so stay tuned.

LMP1 (LeMans Prototype 1 - the big, fast cars)
Once again, it's the classic AUDI/Peugeot matchup for the overall win. Both teams are running diesel engines which have proven to be fast and easy on fuel consumption. Of special note is the introduction of the new AUDI R18, which is a closed-cockpit car (which is a switch from many previous years of open-cockpit AUDIs). This means the tires are narrower, but the new roof (and ungainly trailing dorsal fin) should mean higher speeds and stability along the two long straights at LeMans. As always, we'll be cheering for Tom Kristensen, the most winningest driver in LeMans history. Currently, AUDI holds the #1 and #2 spots, with Kristensen's car in fifth, with Peugeot 908s all around.

Diesel should be an interesting race this year, since the top seven cars are all within 1/2 second of each other.

Henri Pescarolo has come close to an overall win a few times in the past, and his team is always hungry for a win, even after some real heart-breaking finishes. Unfortunately, they've switched to a gasoline-powered engine this year, and will start the race in 9th, nearly eight seconds per lap slower than the pole-sitting AUDI. The Toyota-powered Lolas of the Rebellion Racing team should have an interesting battle all their own with the Pescarolo team, and are on the grid in 8th and 10th place. Unfortunately for the factory Aston Martins, they only managed to qualify in 22nd and 25th positions (20+ seconds per lap slower than the pole-sitting AUDI), so they will not pose a serious threat this year.


LMP2 (smaller, lighter, but less powerful versions of LMP1)
LMP2 typically plays second fiddle (usually third or fourth fiddle) to the rest of the race. The teams keep making them faster, but due to the class rules, the cars end up being tremendously handicapped. In smaller races, LMP2 cars have been known to score an outright win over the faster LMP1 class, but not at LeMans. This, incidentally, is why Roger Penske's Porsche RS Spyders (that dominated the ALMS series) never participated at LeMans. The team was invited, but he declined out of protest since the P2 class was hobbled so much that an overall win wouldn't be possible.

Nevertheless, if the French TV feed decides to show some LMP2 action, enjoy it like you would a rare delicacy. All the cars seem to be within a second of each other, respectively, so it could come down to tire and fuel management to decide the class winner.


LM GTE
This year marks the first year of the LM GTE classes, which are retain 95% of the rules for the class previously known as GT2 (there is no longer a GT1 class). The vehicles are based on road-going cars and must have gasoline engines only. The minimum production number is 100 copies for major manufacturers (25 for small ones), and use an engine of which a minumum of 300 have been made. Cars with carbon chassis are allowed as long as there are a minimum of 300 produced. Engines have to remain in their same location, and supercharged engines have air restrictors.

The end result should be a great "run what you brung" series, with the likes of such enthusiast favorites as the Corvette ZR-1, BMW M3, and Porsche 911 RSR battling with newcomers like the Ferrari 458, Lotus Evora and even an Aston Martin Vantage and a Ford GT.

One of the intriguing things that has been added is the split of the LM GTE class into "PRO" and "AM" classes. The PRO class allows for three professional drivers to pilot each car, while "AM" only allows for one professional driver per car, with the other two being amateurs. Between the driving and the factory money in the PRO class, it should quickly become a game of the "haves" versus the "have nots".

Nevertheless, the ones to watch should be the duels between the Corvette Racing ZR-1s against the BMW Motorsports M3s. The Bimmers set the class lead, with the lead car being nearly 2 seconds per lap faster than both Corvettes. Also keep an eye on the silver/red Porsche 911 RSR of the Flying Lizard team, a particularly talented and fast crew, that is currently 12th in class.

The real X-factors in the LM GTE class are the new Ferrari 458s. Although a PRO team has one sitting 2nd in class at the moment with a blistering speed not far off the lead BMWs, fuel management and reliability could either put the cars out front, or bench them one by one. To no one's surprise, the Lotus Evoras are in dead last, and third from dead last.

Enjoy the show - I know I will!
