Lexus LF-A Roadster Concept stars at Detroit


Images of what’s set to be one of the hottest cars at this week’s Detroit Auto Show, the all-new Lexus LF-A convertible, have leaked onto the Internet just hours before the show officially kicks off. Finished in a striking red paint scheme, the latest LF-A concept has another legendary red supercar clearly in its sights and with its high-revving V10 engine it fits perfectly into the high performance arena.

The new convertible is based on the previous LF-A coupe concept that’s been doing the round of international car shows over the past 12 months. Like the coupe, the roadster features a front mid-engine placement along with a rear-mounted transaxle and rear-mounted radiators for better balance. The V10, capable of more than 500 horsepower and test-track speeds greater than 200 mph, is mounted in front of the passenger compartment but behind the front-axle centerline. It's connected via a torque tube and propeller shaft to a transaxle that is controlled by paddle shifters. The torque tube is a structural member that adds rigidity to the drivetrain and chassis while also reducing vibration.

Though the LF-A is billed as a concept several prototypes have been spotted testing at the Nurburgring, which means this is one concept that will be headed for production. The first cars are tipped to hit showrooms in the first half of next year.

Lexus LF-A Takes on Roadster Form - An Open Version of the Supercar Concept Revealed



DETROIT, Jan. 13 /PRNewswire/ -- The engineers and designers at Lexus

continue to use their groundbreaking LF-A premium sports car concept as a

medium for expressing their ideas about what a high-performance sporting

vehicle not only can be, but should be. In this latest expression of the

LF- A, they have removed the car's top to create a high-performance

roadster.

The LF-A Roadster is based on the sturdy yet lightweight carbon-fiber

and aluminum body used for the LF-A coupe, which helps maintain the

structure's strength and rigidity even without a top.

Like its coupe counterpart, the LF-A Roadster is powered by a

high-revving V10 engine that approaches 5.0 liters in displacement. The

V10, capable of more than 500 horsepower and test-track speeds greater than

200 mph, is mounted in front of the passenger compartment but behind the

front-axle centerline in what the LF-A's engineers refer to as a

"front-mid" configuration.

The engine is connected via a torque tube and propeller shaft to a

transaxle that is controlled by paddle shifters. The torque tube is a

structural member that adds rigidity to the drivetrain and chassis while

also reducing vibration.

Styling is rooted in the Lexus L-Finesse design philosophy, conferring

the LF-A Roadster's front end with a compact, low-profile, aerodynamic

shape. Like its coupe counterpart, the LF-A Roadster stands just 48 inches

tall, but the Roadster configuration adds a speed adaptive rear wing.

The rear is marked by a pair of wrap-around, arrowhead-shaped

taillights that bracket a pair of large grilles. These grilles vent the

heated air from the car's two rear-mounted radiators into the LF-A

Roadster's aerodynamic wake. The radiators are fed cool air by two large

intake ducts mounted just above the rear wheel wells. This aft radiator

positioning not only allowed the designers to keep the car's front profile

low and tight but also aided the LF-A's chassis engineers in their search

for optimal weight distribution.

Helping to provide balance and scale to the design, which features an

overall length of 175.6 inches and a wheelbase of 102.6 inches, are high-

performance tires on turbine-styled alloy wheels. The front tires are

265/35R20s, while the rears are 305/30R20s. Like the LF-A coupe, the brakes

consist of 14.2-inch cross-drilled, vented discs up front, and 13.6-inch

cross-drilled, vented discs at the rear. The front brake calipers are six-

piston units and the rear calipers use four pistons each.

An "F" logo, located on each front fender of the Roadster, indicates

the vehicle's status as a part of the new "F" marque. The name is derived

from the original "F" designation for the first Lexus LS prototype. That

vehicle was internally coded "Circle-F," with the "F" standing for

"flagship." The Circle-F designation further evolved into the code name

Flagship One, or F1, and the first F1 concept developed into Lexus' first

vehicle, the LS. Since then, the "F" code has come to signify a special

vehicle program within Lexus that falls outside the normal engineering and

development process. In addition, Fuji Speedway is the IS F's home circuit,

and the shape of the F- logo was inspired by many of the track's turns. The

all-new Lexus IS F sport sedan is the first production vehicle to carry the

F marque.

  1. 5.0 liters? Too much for me, Toyota, please copy Nissan. Honda, please do a second-gen NSX, but with the original engine displacement.

  2. With every incarnation this car becomes more and more gorgeous.Lexus had better put it into production before someone dies from gorgeous-concept-car-overload-syndrome! Thank goodness I can't afford one.I'd never be able to choose between the coupé and the roadster,never mind colours.

  3. Does the F-A in LF-A stand for "F**kin' Awesome?" The only thing I'd ask for would be a traditional manual transmission option even though yes, it's slower. I think I'd enjoy shifting with an H-pattern gearbox, heel-toe downshifting and manual rev-matching more than having this supercar do it for me. Take some notes from Honda's S2000 and NSX for the gearbox quality. Other than that, I think Toyota's got a legit supercar.

    I'd love to see thing run a Time Attack against the GT-R around the 'Ring. If I were "well-off" I'd get the GT-R. If I were filthy rich, sign me up for an LF-A coupe.

  6. I prefer the graceful lines of the fixed Coupe's design as it appears far more handsome than the convertible in my opinion. In addition to a street version of the LFA, I'm awaiting a true (big) successor to the SC and the IS Coupe/Convertible. L/L
