When I was thirteen, I was
ecstatic to have seen, and been able to identify, the angular Lotus Esprit,
especially given how rare they were in the United States (U.S.) at that time. A
deviation from the subtle roundness of the late 1960 “mod” models such as the
Elan, James Bond’s sweet submersible Esprit, aptly nicknamed “Wet Nellie”,
debuted that same year in the film For
Your Eyes Only, helping Lotus make a splash into the U.S. market.
"Simplify, then add
lightness," declared Lotus’ founder in 1952, establishing the company’s
design parameters. That’s what my current life is all about, keeping it simple
and light.
After my youngest became
engaged and moved in with her fiancé, I put everything into storage and drove
west. A year and 17 states later, driving on Route 89 south to 395 from Lake
Tahoe to San Bernardino in my five-speed Celica, I seriously itched for a more
powerful ride.
A gear-head wannabe, I had
fallen hard for sport cars early on, long before I understood that the world of
fast cars, let alone the road to Formula One (F-1) racing, was still virtually
barricaded to women. While there will always be trend setters who drive head on
through such barricades, I was not destined to be one of them. High speeding
women like Grand Prix drivers Lella Lombardi and Giovanna Amati drove cars I
could only dream about as I schlepped my kids around in much more practical
“family” vehicles.
I even selected a practical
sports car when I became an empty-nester, choosing one with a hatchback that
would enable me to take the recycling to the county’s collection depot. One
that would get reasonable gas mileage.
A few years later however,
leaning into the curves on the outstanding California back roads with awe
inspiring vistas high in the Sierra Nevada’s, I was wishing I hadn’t been quite
so practical in purchasing my ultra-light 1.8 liter 4 cylinder rice-burner with
its barely sufferable 140 horsepower.
Lusting for more power and
better overall handling as I was, any semblance of a social conscience would
have dissolved instantly had I been strapped in behind a roaring V10 engine
with 650 horsepower, oh say like the Dodge Viper, yielding maybe 15 miles to
the gallon on a good day, if I was lucky, and
had the wind at my back. Thankfully, looming on the horizon are cleaner
roadsters expected to ensure a guilt-free exhilarating ride at comparable
prices.
For the record, there are
several factors that contribute to my considering a sports car a good ride and,
ironically, top speed isn’t one of them.
Firstly, understand that
sports cars are high performing vehicles with integrated capabilities that
exceed those of standard vehicles specifically with the intent to enhance the
driving experience. Primarily, I like my ride low and wide because there is
undeniably an obvious difference driving a car equipped with a wide axel stance
and thick tires. Tires, as they relate to cornering (gripping) and steering,
can make or break your ride as much as acceleration, or more specifically
torque, can. A smooth ride is an absolute must and factors that enhance the
driving experience for a gal like me include aerodynamics, brakes and
suspension, seat contour and support, cockpit layout and utility, mirror
positioning, and the noise factor. And call me picky, but I want juice when I
need it. That’s where torque comes into the scenario.
Simplified, acceleration
results from the power, (as in horse), produced by the torque and revolutions
per minute (RPMs) of the crankshaft that through the car’s transmission and
rotor enables the wheels to turn. Horsepower is the rate at which it takes a
car to achieve peak torque, i.e. the actual output of power in a given timeframe.
Thus, the horsepower required for acceleration is dependent on torque. Although
both affect overall performance, it’s the torque that’s felt during
acceleration. It’s the torque we yearn for.
An internal combustion
engine does not produce peak torque until the RPMs are in the thousands. Gears,
or multi-speed transmissions, stretch out the peak torque that has a tendency
to dissipate rapidly. With an electric motor, peak torque is available
immediately and isn’t reliant on high RPMs, negating the need for, or
usefulness of, gears. This makes the electric motor much more efficient than
its petro peer.
Point in fact is the well
publicized zero-emission all electric Tesla Sport Roadster with its 288 peak
horsepower and 295 pounds per foot of torque currently in production. It
accelerates from 0 to 60 in 3.7 seconds, which is a faster rate than that of
most sports cars on the mass market. To give you a perspective, the $484K
Porsche Carrera GT makes 0-60 in 3.9 seconds. Although its 125 mile per hour
(mph) top speed is half that of other sports cars, the Roadster exhibits
performance capacity comparable to the competitively priced Viper and ZR1
Corvette selling at $90K and $110K respectively.
Founded in 2003 by Silicon
Valley engineers with a global vision to “catalyze change,” Tesla Motors
Incorporated produces a variety of high performance zero-emission vehicles
affordable to mainstream consumers. The sleek Model S hatchback, Tesla’s high
performance four door coupe is marketed at half the price of the Roadster, (which
is no longer in production), with base price of $64K. This price puts it in the
ballpark with some of the more affordable sports cars on the market today, such
as the BMW Z4 with selling price of about $62K.
Tesla also makes a seven
seater all wheel drive called Model X, an all electric crossover with gullwing
doors,with a base price of $75K. Their prototype Model E that will be the
company’s first mass-marketed, 200 mile per charge electric car is expected to
cost just $35,000.
But, Tesla Motors is not the only electric car
company trying to tap into the rapidly growing “green” market. Competitor Venturi opened
its North American Headquarters in Columbus, Ohio in order to manufacture and
distribute the America, modeled after the mother company’s 300 horsepower, 280
pounds per foot of torque Fetish launched in Europe in 2004, which accelerates
from 0 to 60 in 4 seconds and whose top speed has been recorded at 320 mph, far
exceeding the 257 mph clocked by the SSC Ultimate Aero, generally considered to
be the fastest sports car in the world.
Like the Tesla Roadster, the
America will top out at about 125 mph. Unlike the Tesla, the more expensive
high body America is being targeted to the new and upcoming luxury sports
crossover market as a mixed-use all-terrain leisure vehicle. The expected $580K
price tag on Venturi’s dune-buggy/sports car does not even include doors as do
the other expensive supercars that these electric models are up against, such
as the $475K+ Mercedes-Benz SLR McLaren and Ferrari Enzo. None-the-less, the
founders of Venturi are visionaries as well since they aim to provide practical
solutions to ending petro dependency and eliminating the related emissions
polluting our air.
At the turn of the last
century, six years after her husband introduced the dashing Model T to the
world, a very modern, eco-chique Clara Ford was driving a 1914 Detroit Electric
Model 47 Brougham hot off the assembly lines, marketed on its facility of the
push-button ignition that eliminated the need to stand out in the weather ankle
deep in dirt to turn the hand crank. Women took to the road in droves and by
the mid twenties, automobile manufactures were actively marketing to women as
drivers, not just passengers. Today, women comprise more than half the market
for new cars, spending just shy of a $100 billion annually on combustion engine
vehicles that haven’t improved on gas mileage much since the 20 mpg Model T hit
the dusty streets a century ago.
As they were more than one
hundred years ago, today’s electric vehicles (EVs) are simple to operate and
maintain. Oil changes, tune-ups, emission tests become a thing of the past with
electric motors. There are fewer repairs because there are fewer parts, and
they produce no particulate matter or noise pollution.
Best part, though, is that
they cost less to run. According to the Pacific Gas and Electric Company, an EV
traveling 40 miles a day costs as little as $.56 to charge during off-peak
meter hours. At $3.50+ per gallon, comparable petro internal combustion engine
vehicles can cost more than $5.00 in fuel a day to drive the same distance.
And, unlike conventional cars, electric motorized vehicles can be recharged by
rebate eligible solar panels, liberating the owner in perpetuity from petroleum
dependency, foreign or national.
With a whopping 300 mile,
(or five hour), driving range thanks to an extensive lithium-ion battery bank
that includes almost 7,000 cells, Tesla’s high performance EVs are hardly limited
by their electric motors. However, not every EV can boast such an expansive
range. In fact, all the electric cars soon to be appearing on the U.S. market
will have a driving range of 80-100 miles including Nissan’s LEAF, Ford’s Focus
and the compact Transit Connect Van, Mitsubishi’s iMiEV, Think’s City Car, the
Coda, and the Smart4two from Daimler. BMW’s Field Trail of their all electric
Mini-E sent engineers back to the drawing board to correct battery issues that
resulted from cold climate testing. But, it too will yield the diminutive 100
mile driving range.
This range wouldn’t have
come close to accommodating my former extreme commute defined by the U.S.
Census Bureau as one that consumes 90+ minutes, (or 90+ miles), each way. But,
for the more than 130 million people commuting only about 40 miles a day, 75
percent of which shamefully drive alone, this lower range would be sufficient.
Although the battery packs
used by EV manufacturers vary in both size and type, most dealerships are
claiming that the “5-10” year battery lifespan depends on both weather
conditions and the frequency of rapid recharges, (i.e. 440-volt charging units
that can provide a 75 percent charge in under an hour versus the overnight
lower volt standard outlet systems). Under “normal” driving conditions, lithium
battery packs are expected to retain up to 70 percent capacity after 5 years or
50,000 miles, and some even up to 80 percent after 10 years or 100,000 miles.
Tesla’s packs are expected to last 7 years or 100,000 miles.
As with other auto
manufactures, they offer bumper-to-bumper 3-year, 36,000-mile warranty, an
extended power train warranty and a battery replacement warranty. With EV
battery packs ranging in price from $10,000 to $36,000, other dealerships may
follow Tesla’s lead by offering buyers a discounted pre-purchase option for
pack replacement. With vehicle 100,000 mile life fuel and standard maintenance
costs for gas models beginning at $12,500 and $2,000, respectively, the battery
replacement costs aren’t as scary as they initially seem.
Currently available federal,
state and county tax credits, which in some areas can total almost $13,000,
provide added incentive towards the purchase of both EVs. EVs receive a full
waiver on all sales, luxury and use taxes in some states and are eligible to
utilize high occupancy commuter lanes and free parking. I’d have to say though,
the fact that Tesla Motor’s Service Rangers make house calls is what tips the
scales for me.
Driving an EV is a quiet,
smooth, fun experience not to be missed. With dealerships and recharging
stations going up all across the country, and Tesla’s collectible Roadster in
its last year of production, eco-savvy consumers are lining up for their very
own test-drives. Although almost half the acceleration speed of the stock cars
that contemporary Indy drivers Danica Patrick, Sarah Fisher, and Milka Duno are
accustomed to driving, I’m certain even these professional drivers would be
hard pressed to not enjoy plunging Tesla’s silent, breathe easy Roadster down the
steep switchbacks along California highway 89 and tearing across the wide open
stretches further on down Route 395.
A word of advice: do as the
professionals do. Tie back your hair, ditch the heels, clip the nails and omit
the lip gloss. Be sure to plan ahead by scheduling your test drive on a breezy,
sunny day, locating the perfect back road with climbs and corners, and prepare
to lean back into the contoured seats to experience the ride of the century.
