the Scirocco
Editors Note: The new Scirocco is *NOT* going to be sold in the U.S. at this time. VWoA feels the new Scirocco is too similar to the GTI in form and doesn't make sense to bring over. While we think the new Scirocco looks better than the IROC concept, it still isn't what a proper Scirocco should look like. Volkswagen had a beautiful opportunity to build a great looking coupe that would be unique in the lineup and instead has built a hotter GTI. As much as we like the way this thing looks on its own, we're disappointed the "new" Scirocco didn't turn out like it could have.
• Providing for ample power on the Scirocco – which comes with ESP and sport chassis as standard equipment – are four TDI and TSI engines, all of them charged and therefore just as torque-strong as they are economical and low in emissions. The three TSIs (gasoline direct-injection) output 90 kW / 122 PS, 118 kW / 160 PS and 147 kW / 200 PS. The Scirocco’s common rail engine (TDI) develops a power of 103 kW / 140 PS.

• Further high-tech elements of the Scirocco: a 7-speed DSG and an “adaptive chassis control system”. Meanwhile, a large panorama vent sunroof – extending from the A pillars to the B pillars – provides for plenty of light in the interior. At the press of a button the transparent panorama roof is raised up to 39 millimeters. When the sun is too intense, a sunshade may be moved into place. But that is seldom likely to be necessary, since the glass of the panorama vent roof reflects 99 percent of UV radiation, 97 percent of infrared radiation (heat) and 80 percent of visible light.
• The new Scirocco is one of the most attractive sports cars in the world when it comes to pricing. Nonetheless, the standard equipment package is super. Always there, for example, are 17-inch alloy wheels, height adjustable driver and front passenger seats and steering wheel, leather parking brake grip, sport seats, split folding rear seats, power windows, air conditioning, ESP, braking assistant, six airbags, speed-dependent power steering, and of course a sport chassis.

Calculating motorcycle and automotive performance
Formulas for Calculating Performance
Convert between 1/4 mile and 1/8 mile ET's
1/4 mile ET = 1/8 mile ET x 1.5832 (thanks to Bobby Mosher for this formula)
1/8 mile ET = 1/4 mile ET / 1.5832 (thanks to Bobby Mosher for this formula)
Calculate 1/4 mile ET and MPH from HP and Weight
ET = ((Weight / HP)^.333) * 5.825
MPH = ((HP / Weight)^.333) * 234
Calculate HP From ET and Weight
HP = (Weight / ((ET/5.825)^3))
Calculate HP From MPH and Weight
HP = (((MPH / 234)^3) * Weight)
Formulas for displacement, bore and stroke
pi/4 = 0.7853982
cylinder volume = pi/4 x bore^2 x stroke
stroke = displacement / (pi/4 x bore^2 x number of cylinders)
Formulas for compression ratio
(CylVolume + ChamberVolume) / ChamberVolume
cylinder volume = pi/4 x bore^2 x stroke
chamber volume = cylinder volume / compression ratio - 1.0
displacement ratio = cylinder volume / chamber volume
amount to mill = (new disp. ratio - old disp. ratio / new disp. ratio x old disp. ratio) x stroke
Formulas for piston speed
piston speed in fpm = stroke in inches x rpm / 6
rpm = piston speed in fpm x 6 / stroke in inches
Formulas for brake horsepower
horsepower = rpm x torque / 5252
torque = 5252 x horsepower / rpm
brake specific fuel consumption = fuel pounds per hour / brake horsepower
bhp loss = elevation in feet / 1000 x 0.03 x bhp at sea level
Formulas for indicated horsepower & torque
horsepower = mep x displcement x rpm / 792,00
torque = mep x displacement / 150.8
mep = hp x 792,000 / displacement x rpm
mep = hp x 792,000 / displacement x rpm
mechanical efficiency = brake output / indocated output x 100
friction output = indicated output - brake output
taxable horsepower = bore2 x cylinders / 2.5
Formulas for air capacity & volumetric efficiency
theoretical cfm = rpm x displacement / 3456
volumetric efficiency = actual cfm / theoretical cfm x 100
street carb cfm = rpm x displacement / 3456 x 0.85
racing carb cfm = rpm x displacement / 3456 x 1.1
Formulas for tire size & their effect
effective ratio = (old tire diameter / new tire diameter) x original ratio
actual mph = (new tire diameter / old tire diameter) x actual mph
Formulas for g force & weight transfer
drive wheel torque = flywheel torque x first gear x final drive x 0.85
wheel thrust = drive wheel torque / rolling radius
g = wheel thrust / weight
weight transfer = weight x cg height / wheelbase x g
lateral acceleration = 1.227 x raduis / time^2
lateral weight transfer = weight x cg height / wheel track x g
centrufugal force = weight x g
Formulas for shift points
rpm after shift = ratio shift into / ratio shift from x rpm before shift
driveshaft torque = flywheel torque x transmission ratio
Formula for instrument error
actual mph = 3600 / seconds per mile
speedometer error percent = difference between actual and indicated speed / actual speed x 100
indicated distance = odometer reading at finish - odometer reading at start
odometer error percent = difference between actual and indicated distances / actual distance x 100
Formulas for MPH RPM gears & tires
mph = (rpm x tire diameter) / (gear ratio x 336)
rpm = (mph x gear ratio x 336) / tire daimeter
gear ratio = (rpm x tire diameter) / (mph x 336)
tire diameter = (mph x gear ratio x 336) / rpm
Formulas for weight distribution
percent of weight on wheels = weight on wheels / overweight x 100
increased weight on wheels = [ distance of cg from wheels / wheelbase x weight ] + weight
Formulas for center of gravity
cj location behind front wheels = rear wheel weights / overall weight x wheelbase
cg location off-center to heavy side = track / 2 - [ weight on light side / overall weight ] x track
cg height = [ level wheelbase x raised wheelbase x added weight on scale / distance raised ] x overall weight

一大早去牽車，旁邊是一家美而美早餐店，老闆娘每天都打扮的像日本藝妓一樣‧‧‧
今天‧‧‧
一台SUZUKI 休旅車停在門口，熄火‧‧‧竟然下來四個打扮和早餐店老闆娘一樣的阿桑‧‧‧
還好是早上，不然‧‧‧我準會被嚇到
