Tuner Tuesday: 2006 BMW M5 Dinan 5.8

Nate’s look at the E34 and E39 Dinan M5s over the past week is a poignant reminder of the factory-backed performance available in these super sedans. In the best style of “Q-Ships” – World War II merchant ships that hid surprising armament behind their docile exterior – they’re turned up but never outrageous. When it came to the E60 chassis though, with 500 horsepower on tap how did one increase the already world-beating performance? In Dinan’s case, there was no replacement for displacement, as they punched out the 5 liter V10 to 5.8 liters. The result was an additional 100 horsepower and around 80 lb.ft more torque while still maintaining the stratospheric redline. Yet that insane performance was available in a wrapper which looked no different than a standard M5:

1991 BMW M5 Dinan 3.9 – Revisit


The E34 M5 may be the least-loved of the breed, but who is going to argue with a 3.9 liter stroker S38? I adore my S38B35, and the thought of a torquier, gnarlier Dinanified inline-6 with an extra pint of volume makes me tingle. This Calypso Red M5 has made the rounds, first selling on BaT in 2012 for a relative pittance before spending the last year-plus trying to spin a profit. The speculative seller has repainted it but accrued fewer than 1k miles, making clear his intentions to cash in on a rare, tuned M-car. The reality that E34s aren’t appreciating like E30s or E38s has apparently begun to set in, as he’s asking now asking $6,500 less than in 11/2014. If you’re looking for a monster E34, this is probably the way to go. But when you could be getting an E39 with 60 more horsepower and a generation newer everything, does anyone like the E34 enough to pay the premium? I’m guessing the seller is going to have to have more patience or less pride before this M5 can start spinning its wheels again with a real driver.

Feature Listing: 1999 BMW M Roadster with AC Schnitzer and Dinan Modifications

With all the hoopla surrounding the BMW M Coupe, it’s easy to forget about its sibling, the M Roadster. This wide-hipped roadster offers a lot of power in a very small package along with the ability to drop the top and listen to the noise of that straight six out the quad tailpipes. This Estoril Blue M Roadster is for sale from former GCFSB contributor Aaron Kraljev in Portland, Oregon. This M Roadster was his personal car and has been meticulously maintained. It also comes with a host of nice options and accessories, such as the hardtop, AC Schnitzer alloys and exhaust along with Dinan performance software. Looking to stand out a bit with your M Roadster?

Double Take – Almost M: 2006 and 2008 BMW 550is

It seems that with every progressive generation of BMW 5-series, the gap between the outgoing M5 and the top of the line non-M 5 series narrows considerably. While there wasn’t much of a contest between the E28 M5 and E34 535i, by the end of the E34 run the 540i M Sport was – for all intents and purposes – a M5 without the S38. BMW upped the ante to 400 horsepower in the new E39 M5, once again widening the gap to the 540i model. But the successor E60 545i offered 330 horsepower with matching torque in 2003 alongside the outgoing E39 and once again the gap in performance became much smaller. That gap was made almost impercievable in 2005, when BMW revised the E60 with the increased displacement in the N62 motor. Now sporting 4.8 liters from the N62B48, the new “550i” now had 360 horsepower and 361 lb.ft of torque – a near match for the S62. What was perhaps more amazing was that the new N62 also nearly matched the torque of the new E60 M5’s S85 V10. But while that screaming V10 produced far more horsepower, the peak torque was reached only at 6,100 revolutions – hardly practical in your daily commute. In comparison, peak twist on the N62 came at a much more realistic 3,400 r.p.m.s, and on the fly these 550is were – and still are – seriously quick sedans. They also introduced the next generation of design language and computer technology into the 5-series. Some love the look while others lambaste the design. While it’s certainly not my favorite 5, at least it’s distinctive and different in a world full of cookie-cutter designs and dare I say I think it may look better today than it did new – perhaps a testament to its avant garde lines. While the lust-worthy V10 captures the imagination of enthusiasts, day to day the 550i is likely as fast 95% of the time and much cheaper to get into and run. Today I’ve got two nice examples to consider – which would you sport for?

Tuned BMW E60 M5s

s-l1600 (3)
You might think that a car that has a simple button to raise its power by 100 horses might have enough, but today we have two E60 M5s that will explain to you why that kind of thinking makes you a peacenik ninny. I mean, if you can get a V10 in used Audis, then you have to do something to make your M5 stick out, right? These two E60s take pretty different approaches to power and style – supercharger vs. stroker, manual vs. SMG, Eurotuner vs. Roundel – but both represent about as insane of Autobahn stormers as you can find.
