Frankfurt Motorshow 1999 - Lotus M250
THE M250 CONCEPT CAR -THE START OF SOMETHING SPECIAL
Today at the 58th Internationale Automobil-Ausstellung (I.A.A.)
in Frankfurt, Lotus presents the Project M250 Concept Car - the
latest sportscar development from Lotus.
This two-seater, mid-engined, high performance supercar possesses
world leading aerodynamic downforce combined with unrivalled chassis
stiffness to give a unique driving experience. By being exceptionally
lightweight, the M250 Concept Car achieves sensational performance:
a true Lotus.
Powered by a mid-mounted Lotus-developed 3.0 litre V6 engine that
drives the rear wheels through a six-speed gearbox, the M250 would,
if it was to be built, slot into the Lotus line-up between the Elise
and the Esprit.
Instead of aiming for ultimate top speed, Lotus has placed the
emphasis on driving pleasure in the M250. That said, it will be
brutally fast in everyday driving conditions -0-100km/h (0-62mph)
in less than 5.0 seconds, 0-160 km/h (0-100 mph) in less than 11.0
seconds. Top speed will be electronically limited to
250km/h (155mph), a move which gives Lotus engineers tremendous
freedom to optimise the rest of the car's dynamic qualities and
give it impressive high-speed stability and superb handling.
As it's a Lotus, the M250 is a light car and its unladen weight
will be less than 1000kg -which brings tremendous benefits in terms
of driveability and response to the throttle and steering wheel.
Its power-to-weight ratio will embarrass many rivals, as will its
agility and its levels of driver satisfaction.
Even though the M250 will be equipped with all the standard luxury
items you expect in a car in this price bracket, it isn't lumbered
with the intrusive electronic driver intervention devices that are
taking the fun out of many other sports cars. Although intended
as more of an everyday car than the Elise, the M250 remains a true
instrument for driving.
The Styling -Attitude and Agility
The concept car on display at the I.A.A. is fresh from the Lotus
Engineering's Styling Department's modelling division, based at
Lotus-Coventry, England. The M250 shows the design philosophies
for Lotus cars of the future: a cabin-forward design and short overhangs,
front and rear to create a mean, purposeful look.
Russell Carr, Head of Styling and Design at Lotus, explains: "The
M250 blends sensuous lines with contemporary, crisp design elements,
to give it what we like to refer to as 'attitude'.
"Although it's a ground-up design, we've chosen to give the
M250 visual bond with the Elise and the 340R - you can see the links
in the top-exiting front radiators, the distinctive side air vents,
and in the general proportions of the car; it's compact, agile and
athletic.
"But the M250's overall look is very much its own and we're
extremely proud of the design, particularly the wrap-around windscreen,
which is very similar to a visor on a motorbike helmet."
A major achievement in the M250's design is that it has excellent
aerodynamic properties 'straight out of the box'. Lotus engineers
and designers have used the knowledge learned from designing competition
cars to create a shape with an extremely well balanced aerodynamic
package. Downforce and high speed stability were given priority
over a very low drag coefficient in the design of the M250, and
to manage the airflow underneath the car to conjure up even greater
downforce resulting in a Cz of 0.15.
Lightweight - As Expected from Lotus
The M250 wouldn't be a proper Lotus unless lightweight was an important
part of its genetic make-up; it's an integral part of Lotus Car's
whole philosophy. The concept's chassis improves and develops upon
the bonded extruded aluminium technology used to such great effect
in the Elise.
Lotus engineers are continually investigating new construction
techniques and technology as well as new materials, though such
advances will only be introduced when proven to offer a genuine
advantage - it isn't the Lotus way to use things just because they
look pretty or are fashionable.
There are several innovative options regarding what materials the
body should be made from. All possibilities are being explored including
aluminium/composite construction. In addition to being lightweight,
the body material will support high quality manufacturing techniques.
Lower the weight and you can reduce the power
Rather than enter the horsepower race, Lotus has opted to follow
the more rewarding "power-to-weight" path. Target unladen
weight for the M250 is less than 1000kg, and the expected power
output from the Lotus-developed 3.0-litre V6 is 186kW (250bhp).
Electronically limited to 250 km/h (155mph), the M250 flexes its
muscles at the lower, and more often used, end of the performance
spectrum - standstill to 100km/h (0-62mph) will be achieved in less
than 5.0 seconds, while its sub-11.0 seconds 0-160 km/h (0-100 mph)
time takes it firmly into supercar territory.
"If we decide to build the M250, it will be the best handling
car ever from Lotus," according to Lotus Cars' Managing Director,
Graham Peel, "Throttle response will be superb and the car
will feel agile and truly special to drive. It will sound great,
have a first-rate gear change and excellent ABS-assisted brakes.
"The concept behind the M250 is to produce another superlative
driver's car, in the same mould as the Elise, but with technical
refinements and enhancements made possible through what we've learned
from over 50 years of sportscar development."
However, the M250 will be more of an everyday car than the Elise.
It will have 'creature comforts' such as air-conditioning, central
locking and electric windows. But there won't be any unnecessary
electronically controlled stability aids or traction control devices
- Lotus prefers to produce a responsive and well-behaved chassis
in the first place.
If the car were to go into production and become the next new Lotus
then it would be in European dealers in the first half of 2001,
built in similar volumes to the Elise (currently over 3000 cars
a year).
