    Try and true auto/bike makers toyota, honda, ferrari, M. Benz, yamaha, kawasaki, suzuki, bmw, etc don't use turbo in their sport cars/bikes. Some sport bikes can rev over 10,000 rpm and turbocharging is still not used.

    There is no replacement for displacement.

    Super Power: AMG V8 proves thereís no replacing displacement
    DUTCH MANDEL and GREG KABLE
    Posted Date: 7/15/05
    In what Mercedes-Benz claims to be the most powerful, naturally aspirated eight-cylinder engine extant, the firmís performance arm has developed a powerplant that will make it into virtually all its high-horsepower models.

    M-B claims the 6.2-liter V8 develops ďa minimumĒ of 510 horsepower and 464 lb-ft of torque without a supercharger, and has 20 percent more torque than other free-breathing engines in class. Cars fitted with the engine will get a 6.3-liter badge.

    The engine and cylinder heads are high-strength aluminum and created with the latest metallurgical technology. Cylinder walls undergo a process to minimize friction, increase durability and add strength: The cylinder walls are twice as hard as conventional cast-iron liners.

    AMG developed the engine without Mer-cedes. It has a throaty exhaust note reminiscent of late-1960s Trans-Am cars. It not only sounds better than the supercharged 5.4-liter models it replaces, it is smaller and lighteró438 pounds vs. 485 pounds.

    AMG fitted a CLK DTM street racer with an engine for drive impressions. A bit of a shell game, on-site engineers privately agreed the car developed near 580 horsepower. Regardless, at first blush and full throttle the engine is a torque beast. That the 6.3 can fit in a current C-Class lends expectations that of the 24,000 engines AMG can build annually, they will be spread across the lineup. The 6.3 debuts at this fallís Frankfurt show in an M-Class. It will be available in the States next year.

    wow, what did the dudes do to it? new camshafts, new chip, new ignition system, . . . etc.? No turbocharger & intercooler? And 220 hp is wheel horsepower?

    Horsepower doesn't mean anything by itself. A 600 bhp power car may be easily beaten by a 90 bhp car in an acceleration test. It is power-to weight ratio, OTHBE, that really counts.

    i think ur exaggerating the hp difference in making your point as u didnt specify the test duration. What good is beating a 600hp car for the first 0.25 sec?

    In performance cars power-to-weight ratio, AOTBE, is the key. A 90bhp car like in one model of the Lotus Elite, which weighs 600 kg, will out-accelerate a 600bhp car weighing 4,000 kg, on the straight and on a curve, for 1 minute or an hour, even when both cars have the same power-to-weight ratio. The heavier car is let down by it's massive rotating unsprung weight-huge tyres, brakes, wheels, etc.

    give me a break, who drive around a 4 tonnes car and has 'only' 600 hp?

    a better comparison should be with this foreign car eater AND IT'S A AFFORDABLE CAR.

    http://www.americancarfans.com/spyph...id/6050701.001

    oh, btw, it weighs 1317 kg, power to weight ratio=0.46 vs your lotus of measly 0.15


    taneepak, if a car is 4000 kg, u need to up the hp to like this one

    Cooler, you have now come around and are talking sense, like "...power to weight ratio=0.46 vs your Lotus measly 0.15". See what I mean?

    i 'never had to' come around, it's in me all the time The problem with your comparison is that it has very limited application. Your lotus elite excel in low speed and/or short distance and/or for short duration, so what. There are many things in nature that can blow away both lotus elite and blue devil corvette. Take an ant, it has far more power than any cars compare to its weight. A dog flea, about the size of a pinhead, it can jump about 100 times its own height, a far greater leap than that possible for the multi-million dollar basketball player. However, can they do those feats when i sit on top of them? How about your lotus elite if a couple (american size) get on it with some golf equips or camping gears, watch the lotus elite performance go south, FAST The only time when i refer the 90 hp lotus elite as 'fast', LOL

    Also, power to weight ratio alone isnt everything. There are many other design parameters that can enhance or degrade acceleration

    On it is right. they won't get IN it !

    I thought he meant the Elise at first, but as the Elite is a 40 year old car I guess he really means the Elite.
    Dunno why pick the Elite though if you're after acceleration. Closest model to that described that i can see is the 1962 @ 660kg and 83bhp 0-60mph 11s (maybe there was a sportier version back in the day)
    why not go for the recent Exige @ 930kg 243bhp 0-60mph 3.9s

    Are you sure? Elise uses Toyota Cecila & Matrix high-output I-4 engines.

    It doesn't matter which lotus, "In performance cars power-to-weight ratio, AOTBE, is the key" was your be all end all claim.

    There are many models and modified version of lotus elite, lets compare FACTORY VERSION and a factory version of a american truck.

    From these links:

    AND COMPARE TO a 2002 CHEVROLET AVALANCHE with 0.11 bhp/kg ratio too.

    2002 Chevy Avalanche
    POWERTRAIN/CHASSIS
    Drivetrain layout Front engine, rwd

    Cargo capacity, cu ft 41.1
    Fuel capacity, gal 31.0
    TEST DATA
    0-60 mph, sec 8.2
    1/4 mile, sec/mph 16.22/83.42
    Braking, 60-0 mph, ft 127
    600-ft slalom, mph 54.5

    bottom line, two vehicle with same power to weight ratio and yet very different 0-60 mph time. A soccer mom auto tranny 4x4 suv beats a agile sport car with manual transmission in acceleration with same power to weight ratio. Even if i assume that moter trend technican used the best time for the 2002 avalanche, let me give it some slack and add another 0.5 sec on top of best time of 8.2 sec, this truck is still under 9 sec compare to a lotus sport car of 10.7 sec. Displacement rules and i really didn't come completely around

    but cooler,
    you haven't kept all other things equal
    I can see some differences between those two vehicles
