[glow=red,2,300]Indy 500[/glow]

Κυρίες και κύριοι, την Κυριακή έχουμε τον δεύτερο σε σημασία αγώνα του μηχανοκίνητου αθλητισμού, τα φημισμένα 500 μίλια της Ινδιανάπολης. Η 92η έκδοση του Ιndy 500 στο ναό της ταχύτητας, το θρυλικό ”Βrickyard”.

To Indianapolis Motor Speedway είναι η παλαιότερη πίστα του κόσμου που χρησιμοποιείται ακόμα, καθώς η κατασκευή της ολοκληρώθηκε το 1909. Αρχικά, επρόκειτο για μια οβάλ πίστα, με οδόστρωμα από τριμμένη πέτρα και πίσσα. Ωστόσο τα πολυάριθμα θανατηφόρα ατυχήματα επέβαλαν το στρώσιμο της χάραξης με τούβλα. Για αυτό το λόγο η πίστα ονομάστηκε Brickyard (μτφ: ”αυλή από τούβλα”). Από το 1911, στην Ινδιανάπολη διεξάγεται ένας από τους μεγαλύτερους θεσμούς στην ιστορία του μηχανοκίνητου αθλητισμού: τα 500 μίλια.
Μάλιστα, ο αγώνας αποτελούσε μέρος του καλανταριού της Formula 1 για μια δεκαετία: από το 1950 μέχρι το 1960. Από το 1952 ξεκίνησαν οι προσπάθειες επικράτησης στον αγώνα από τις ευρωπαϊκές ομάδες, καθώς η Ferrari συμμετείχε στον αγώνα με τον Alberto Ascari, ο οποίος ωστόσο εγκατέλειψε μετά από 40 γύρους (σε σύνολο 200). Την αποστολή αυτή ανέλαβε να φέρει εις πέρας το 1965 ο Jim Clark με μια Lotus-Ford Cosworth (με κινητήρα τοποθετημένο στην πλάτη του πιλότoυ). Ωστόσο μέχρι τότε η πίστα είχε δεχθεί μια σημαντική επέμβαση: τα τούβλα είχαν αντικατασταθεί το 1961 με ασφαλτοτάπητα, αν και μια λεπτή γραμμή τούβλων παραμένει ακόμη στη γραμμή εκκίνησης-τερματισμού στη μνήμη του ”Brickyard”.
Στους νικητές του αγώνα συγκαταλέγονται οι γνωστοί μας απ’τη Formula 1 Jim Clark, Graham Hill, Mario Andretti, Emerson Fittipaldi, Jacques Villeneuve και Juan Pablo Montoya. Πολυνίκες του Indy με 4 νίκες οι A.J. Foyt (ο θεωρούμενος ως ο καλύτερος Αμερικανός οδηγός όλων των εποχών), Al Unser και Rick Mears. Πολυνίκης ομάδα αυτή του Roger Penske με 14 νίκες. Η μεγαλύτερη μ.ω.τ. που έχει καταγραφεί είναι 385.052 km/h!!!
Τέλος, τα 500 μίλια της Ινδιανάπολης έχουν στοιχίσει τις περισσότερες ζωές πιλότων από κάθε άλλο αγώνα, με 13 τον αριθμό να έχουν σκοτωθεί. Αν συνυπολογίσουμε πιλότους που σκοτώθηκαν σε δοκιμές, μηχανικούς, θεατές και κριτές ο αριθμός φτάνει τους 65... Εκτός των ανθρώπων μέσα στην πίστα, έμελλε να χάσει τη ζωή του και ένα δωδεκάχρονο αγόρι το 1931, όταν μετά από ατύχημα κατά τη διάρκεια του αγώνα ένας τροχός εκσφενδονίστηκε έξω απ’την πίστα και χτύπησε το παιδί που έπαιζε στην αυλή του...

Η ιστορια της BMW 8 Series

Πηγη wikipedia.org

http://en.wikipedia.org/wiki/BMW_8_Series#M8

The BMW 8 Series (chassis code BMW E31) is a V8 or V12-engined 2-door 2+2 coupe built by BMW from 1989 to 1999.

While it did supplant the original E24 based 6 Series in 1989, a common misconception is that the 8 Series was developed as a successor. However, it was actually an entirely new class aimed at a different market, with a substantially higher price point and better performance than the 6 series. The 8 Series was designed as a direct competitor to the upcoming Mercedes-Benz SL-Class and S-Class coupes (later renamed the CL-Class). While it has less rear passenger volume than the sedan-based CL, the 8 Series could accommodate two passengers in the rear, while the SL roadster is a two-seater.

The BMW 8 Series was BMW's flagship car while in production. A new vehicle cost around US$100,000 and had an electronically limited top speed of 155 mph (250 km/h), although with the limiters removed top speed was estimated at 186 mph (299 km/h). Worldwide production ceased May 12, 1999, with 30,621 built.

BMW is rumored to have plans to revive the 8 Series name for a potential "four-door coupe," much like the Mercedes-Benz CLS-Class. The existing E63/E64 6-Series two-door coupe currently completes with the CLS-Class in that price point.

History
Design of the 8 Series began in 1984, with construction starting in 1986. The 8 Series debuted at the Frankfurt Motor Show (IAA) in early September 1989. The 8 Series was designed to move beyond the market of the original 6 Series. The 8 and 6 Series cars were distinctly different in design; though both were Grand Touring cars, the 8 Series had substantially improved performance.

Over 1.5 billion Deutschmark was spent on total development (2005 USD $2.2 billion). BMW used CAD tools, still unusual at the time, to design the car's all-new body. Combined with wind tunnel testing, the resulting car had a drag coefficient of 0.29, a major improvement from the previous BMW M6/635CSi's 0.39.

The 8 Series offered the first V12 engine mated to a 6-speed manual gearbox on a road car. It was also the first vehicle with an electronic "fly-by-wire" throttle. The 8 Series was one of BMW's first cars, together with the Z1, to use a a multi-link rear axle.

While CAD modeling allowed the car's unibody to be 8 lb (3 kg) lighter than that of its predecessor, the car was significantly heavier when completed due to the large engine and added luxury items—a source of criticism from those who wanted BMW to concentrate on the driving experience.

Sales of the 8 Series were affected by the global recession of the early 1990s, the Persian Gulf War, and energy price spikes. BMW pulled the 8 Series out of the North American market in 1997, selling only 7,232 cars over seven years. BMW continued production for Europe until 1999, though only as the 840Ci. The ultimate worldwide production total was 30,621.

830i
Although sales were good in the first year on sale, the sharp reduction of the expensive 850i sales prompted BMW to develop an entry-level model. This was to use the 3-liter V8 with 218 bhp (163 kW/221 PS) from the 530i and 730i, known internally as the M60B30. Eighteen cars were produced, 13 of which had an automatic gearbox fitted. The model was dropped in favor of the 840Ci and all 18 development cars were dismantled.

840Ci

BMW 840CiThe 840Ci exists with two different engine packages. The first used the 4 liter M60B40 engine with 286 hp (213 kW) and was produced from mid 1993 to late 1995. From mid-1995, production phased in the newer 4.4 liter M62B44 engine, which had better fuel economy and more torque, though power output remained unchanged.

The 840Ci was available with a 5-speed automatic transmission, though European cars were given the option of a 6-speed manual transmission. The only external features distinguishing the V8 model from the V12 models were the quad round exhausts, which were square in the V12 models.

The 840Ci stayed in production until mid-1999, though export to the US stopped in 1997.
850i
This was the first model launched in 1989 with the 5 liter M70B50 engine producing 300 bhp (224 kW/304 PS). It was available with either a 4-speed automatic or a 6-speed manual gearbox.


850Ci
There is some confusion over why and when the 850i became the 850Ci. The change happened around the introduction of the 850CSi and it is believed that BMW decided to include the "C" in the model name to create more of a distinction between the 8 Series and BMW's sedans. The confusion starts when BMW installed the new M73B54 engine in the car. This was not an immediate changeover, and indeed both the M70 and M73-engined cars rolled off the production lines side-by-side for about nine months in 1994, both named 850Ci.

As the capacity of the M73 increased to 5.4 liters and the compression ratio went up, the power output rose to 326 bhp (243 kW/331 PS).

850CSi
As a top-of-the-range sports tourer, the 850CSi took over from the prototype M8. The 850CSi used the same engine as the 850i, which was tuned so significantly that BMW assigned it a new engine code: S70B56. The modifications included a capacity increase to 5.7 liters and power increase to 390 bhp (291 kW/395 PS).

The 850CSi's modified suspension included stiffer springs and dampers and reduced the car's ride height. The model also sported wider wheels, with the option of forged alloys. The front and rear bumpers were reshaped for improved aerodynamic performance. Four round stainless steel exhaust pipes replaced the square pipes found on other models. The 6-speed manual gearbox was the only transmission option.

Production ended in late 1996 because the S70 engine could not be modified to comply with new emission regulations without substantial re-engineering.

M8
One of BMW's best-kept secrets is the canceled BMW M8 Prototype. Originally envisioned as a Ferrari competitor, only a single prototype was ever produced, equipped with a special 550 bhp (410 kW) version of the S70 engine, essentially a bored out version of the M70 with experimental multi valve cylinder heads. A common misconception is that this engine eventually ended up in the McLaren F1. However, when this was suggested to McLaren's designer Gordon Murray, the idea was rejected because the engine was overweight and too long for the McLaren F1. A whole new engine was designed which has a closer resemblance to the later euro S50B30 BMW M3 engine.

The project was eventually scrapped because BMW decided that there was no market for an M8. The only prototype ever produced (one that was reportedly not even road safe) was locked away by BMW in the company's Giftschrank (poison storage) and has reportedly been destroyed[1].

While the M8 was never produced, it is interesting to note that the 850CSi was also tuned by BMW's "M" division. Aside from sporting an M-tuned engine (as identified by the S suffix instead of the M prefix that a true M car would wear), the car's VIN identifies the car as being built by BMW Motorsport (identified by the WBS prefix) instead of BMW AG (WBA prefix). This effectively identifies the 850CSi as essentially a detuned version of the M8[2].
Alpina B12
BMW tuner Alpina produced a special version of the 8 Series dubbed the B12. Two versions were produced, both taken from the standard production line. The B12 5.0 Coupe was based on the 850i, powered by the 5.0-liter M70 engine producing 350 bhp (260 kW), and available only with a 4-speed automatic gearbox. The larger B12 5.7 Coupe was based on the 850CSi, with the 5.7-liter S70 engine producing 416 bhp (310 kW/422 PS) with a 6-speed manual gearbox. All in all, 97 5.0 Coupes and 57 5.7 Coupes were built.


Racing Dynamics K55 Sport Coupe
BMW tuner Racing Dynamics of Italy in 1991 produced a special version of the 8 Series dubbed the K55 Sport Coupe taken from the standard production line. The K55 5.5 Coupe was based on the 850i, powered by the 5.0-liter M70 that was stroked to 5.5 liters, new valves, camshafts lifters and intakes along with extrude honed heads. The one US version engine producing 475 bhp (354 kW/482 PS) and the Euro version producing 401 bph. 40 K55s were produced for the Euro market and one in the US. In addition to engine modifications, The K55 offered a variety of body, suspensions, rear end options. References 02/1994 Euro Magazine Road & Track, Car And Drive [3]

However, there is no verification of 475 hp (354 kW) produced by this car by Racing Dynamics. The K55 produces 380 hp (280 kW) and 405 ft·lbf (549 N·m) of torque as listed in the 02/1994 Euro car magazine. Racing Dynamics' own website lists the K55 at 401 hp (299 kW). [4]

The 475 hp (354 kW) was declared by AutoThority (as listed in the said Road and Track article) who are no longer in business in their original capacity. The 475 hp (354 kW) claim was never verified.

PowerPlant Racing BMW 860i
Race car tuner PowerPlant racing of North Carolina, USA produced the most powerful Naturally Aspirated 8 series BMW. This was done by increasing the displacement of the M70 V12 engine to a 6.0L capacity.

This conversion changes the stroke of the engine from 73mm to 86mm, the bore from 84mm to 86mm and the compression ratio from 8.8/1 to 10/1. The 6.0 conversion on an stock rebuild makes 405 HP & 425 lbs/ft of torque. However there are add on options of this program that increases the specifications to 455+ HP and 500+ lbs/ft (386 HP and 409 lbs/ft torque at the wheels) that is emission legal with completely civilized, stock drivability.[5] [6]

There were only 7 of the 6.0L conversions done for the E31 (BMW 8 Series).

Transmission
The 840Ci (V8) U.S. models were each equipped with a 5-speed automatic transmission. The 850i/850Ci/850CSi (V12) models each carry either a 4-speed automatic transmission, 5-speed automatic transmission, or a 6-speed manual. The 850CSi model only came with a 6-speed manual transmission.

Συμπέρασμα του σημερινού αγώνα: η McLaren βολεύεται στο χάος!!! Θυμηθείτε τι έγινε και στην Αυστραλία...
Μ’αυτά και μ’αυτά ο Hamilton είναι ακόμα στη μάχη του πρωταθλήματος, έχοντας κατώτερο μονοθέσιο.
Φερραρομούρηδες (ή αλογομούρηδες αφού το σήμα της Ferrari είναι το αλογάκι ) δε σας χάλασε που το 1-2 έγινε 3-9!!!
Έτσι βεντούζαααααααααα!!!
