SKY
PILOT
Spending a little time in Saturn’s hot new roadster
By Bruce W. Smith - Special to GCN
A warm breeze wafted through the cockpit as the
twisting road we were driving wound through the valleys and hills, snaking
its way past one Napa Valley vineyard after another. Although the country
road was narrow and the turns, at times, tight, the drive was pure
pleasure.
There’s nothing like driving a quick, smooth rag-top
roadster with the top down on a beautiful day. The experience sweetens
even more when the car has the head-turning styling and performance of a
2007 Saturn Sky.
Saturn is a GM brand that, for all intents and
purposes, has been relatively invisible when it comes to making statements
in design and performance.
But all that has changed. The company has suddenly
taken center stage, introducing four brand new vehicles for 2007. The
two-seat Sky rag-top is the most eye-catching of all—and it’s sure to put
a bite on Mazda MX5 sales.
With dynamic design and quick, agile performance, the
Sky roadster, which will retail for $23,690 for the 2.4L, 177hp, 5-speed
manual version, delivers a bold message about the next generation of
vehicles from Saturn.
The Sky, which will be showing up at dealers any day,
is the first Saturn to feature the brand’s European-influenced design,
which will carry forward to future products.
“ As
we build on our reputation for great customer care, Saturn is introducing
a bold new design and level of refinement with Sky,” says Saturn General
Manager Jill Lajdziak. “The Sky represents the future of the Saturn
brand.”
The Sky is an all-new vehicle that shares the same
underpinnings as the new Pontiac Solstice. Both are built on GM’s new
global rear-wheel drive compact performance platform in both manual and
5-speed automatic ($24,540) versions.
HEAVENLY BODY
Sky has a unique body and interior not shared by the
Solstice. The suspension is also tuned differently, giving the Sky a
slightly softer, but no less agile and stable feel. It carves corners like
it was born for twisting country roads, putting both driver and passenger
totally at ease.
Those around take note as well; the Sky’s
aggressive, edgy and sharp lines gives it a distinctly European look and
commanding road presence noticed by all.
Aside from the cool body, the Sky features 18x8-inch
five-spoke aluminum wheels, Goodyear Eagle RSA P245/45R18 96V,
high-performance all-season tires with a large, wide sport appearance and
aggressive tread pattern that enhances the stance of the car.
The combination offers excellent all-season
performance, excellent longitudinal grip that contributes to best-in-class
stopping distance (60-0 mph in 116 feet) and road gripping ability with a
maximum lateral acceleration of approximately 0.90g. Chrome five-spoke
wheels are available.
It gets down the road like it looks, too. It is
equipped with a 2.4L, 177-horsepower DOHC Ecotec engine with variable
valve timing. EPA fuel mileage is rated at 20/28 for the manual model,
22/26 for the automatic.
As mentioned earlier, the base Sky comes with a
short-throw five-speed Aisin manual transmission or 5-speed automatic.
We loved the manual version; the Aisin five-speed,
which is also found in the GM Colorado/Canyon pickups, takes little more
than a flick of the wrist to change gears. The gates are precise and
shifts velvet smooth.
Sky roadsters also feature electronic throttle
control (ETC) for remarkably precise engine control response.
In fact, the new Sky feels that way in all aspects.
This is a car purpose-built to be a sporty roadster.
“The Sky’s performance pays off on its dynamic
design,” said Tom Wallace, vehicle line executive for GM performance cars.
“We carefully selected the powertrain, suspension and handling components
to provide agile, yet refined, performance.”
INTERIOR REFLECTIONS
At first glance one would think the cockpit would be
too small to be comfortable. Not s. The seat design and interior layout
offers a surprising amount of long-distance comfort for those with long
legs or short.
There’s no door sill to slide over, so entry and
exit, even with the top up, is very easy. The center console is at the
perfect height to rest one’s arm while keeping a hand on the shift lever.
Those into automatics will find similar comfort. The
automatic can be shifted manually or left in the auto mode. It responds
quickly to shift changes, so there’s still plenty of “sport” in the
driving if you are in the mood.
Storage
space is the only downside to the Sky. The roadster is small and the trunk
even smaller. There’s just enough space inside to throw a small overnight
bag and a couple jackets. Nothing more.
But who needs luggage when it’s the driving
experience that brings the smiles. Top down or top up, the new Saturn Sky
is a delight to drive.
Oh, and just in case you like a little more muscle in
your roadster, the turbocharged Saturn Sky Redline will be forthcoming
this fall. Under its hood is a 260hp turbocharged Ecotech four-cylinder
that is said to hit 0-60mph in less than six seconds.
Driving that would definitely make you a Sky Pilot.—Bruce
