The Lexus showcased its new sports convertible, the SC 430, at the Paris Motorshow in 2000, and the car entered production the following year. Power was provided by a 4.3 L 3UZ-FE V8 engine mated to a five-speed automatic transmission. This produces 0-60 runs around 6 seconds using the same engine found in the Lexus LS.
The Lexus designers from Europe and Japan worked together to create the convertible's sleek, streamlined design. The car features a retractable aluminium hardtop, all-leather interior, and 18 in alloy wheels. It can seat four and has a base price of US$63,825.
Competitors include the Mercedes-Benz SL-Class, Cadillac XLR, and Jaguar XK, and BMW 6-series.
The Lexus LS (sold as the Toyota Celsior in Japan, Australia, and some other countries.) is a V8-powered, rear wheel drive luxury car that serves as the flagship of Toyota's luxury Lexus division.
First generation (UF10)
UF10 I (1989)
The UF10 I LS 400 was produced from 1989 to 1994. The model introduced the Lexus nameplate to the US, and soon after won critical acclaim, becoming Wheels magazine's Car of the Year and earning a place on Car and Driver magazine's Ten Best list for 1990. The LS 400 was initially intended to be introduced as a standalone model for Lexus, but ultimately was sold alongside the ES 250, an entry-level luxury car that was based on the Toyota Camry.
UF10 II (1993)
For the 1993 model year, the LS 400 (now designated as the UF10 II) was introduced with larger brake rotors, standard passenger's side front airbags, larger wheels and tires, and numerous other upgrades.
Second generation (UF20)
UF20 III (1995)
Introduced in 1995, the UF20 III LS 400 was an evolutionary redesign of the LS and featured a new body that eliminated 300 lb from the previous car. The wheelbase was increased by 1.4 in, resulting in more interior and trunk space, yet the overall length of the car remained at 196.7 in. The durability of the brake system was improved as well.
The most noticeable cosmetic upgrades included a new front fascia with an increased gap between the headlights and grille, new headlights and taillights. The interior received a minor redesign with a more modern dashboard layout and the center console receiving a slight facelift.
UF20 IV (1998)
Lexus LS430
For the 1998 model year, the UF20 IV LS 400 was introduced. New interior amenities included retractable rear headrests, wood accents on the leather-bound steering wheel and gear selector, and a navigation system with a concealed antenna. A new "jam protection system" for the vehicle's windows was designed to reduce the risk of possible injury by preventing the windows from closing if an object came in between the window and the door frame. Door window controls were also added to the vehicle remote control.
Exterior updates included new five spoke wheels as well as redesigned rear view mirrors that reduced the amount of wind noise. The automatic headlights were now equipped with a delay feature that allowed the headlights to remain on while the occupants exited the vehicle.
The revised LS 400 featured Toyota's new 290 hp VVT-i UZ engine mated to a five-speed automatic transmission. The drivetrain improvements not only enabled the 3,890 lb sedan to accelerate from 0-60 mph in 6.5 seconds but also improved the vehicle's fuel economy.
Third generation (UF30)
UF30 I (2001)
For 2001, the UF30 I LS 430 was introduced. While previous LS redesigns were evolutionary, the 2001 update was a more thorough update of the model's exterior and interior. The UF30 had a completely redesigned suspension and a brand new 4.3 L engine generating 290 hp (216 kW) and 320 ft•lbf (434 N•m) of torque. Lexus claims the LS430 can run 0-60mph in 5.9 seconds. A three-inch wheelbase stretch resulted in more interior volume than the competing Mercedes-Benz S-Class and allowed the engine to be positioned farther rearward for better balance. Features such as Dynamic Laser Cruise Control, a DVD-based navigation system and heated & cooled seats became available. These and other features, such as sonar assisted parking, power rear seats with massage and a rear cooler were bundled in the 'Ultra Luxury Package.'
In the interior the most notable design changes included additional woodgrain trim on the dashboard and doors as well as the addition of an LCD screen on the center console. The exterior of the vehicle was completely new with the vehicle's dimensions increasing in terms of length and height.
UF30 II (2004)
The UF30 II was introduced in 2004. Lexus freshened the front & rear fascias and added as standard equipment previously optional features, such as a one-touch power moonroof, power rear sunshade, and lighted rear-seat vanity mirrors. Some features previously included in the Custom and Ultra Luxury packages became available separately. The transmission got an added sixth gear, and keyless 'smart access' and Bluetooth technology became optional, while a pre-collision system, similar to Mercedes-Benz's Pre-Safe, which used millimeter-wavelength radar to predict crashes and allow distance-aware cruise control, was added as an option. Other updates included different wheels, projector headlamps, and LED taillights.
The 2001 to 2006 LS 430 was the most reliable luxury sedan in the J.D. Power and Associates Initial Quality survey, and the early models of this series were the most reliable cars in the survey. In later studies of defects after 3 years of ownership, the LS 430 is also at the top of the pack. The third season of the popular BBC television program, Spooks, featured a number of Lexus LS vehicles as part of the brand's introduction in the British market.
The Lexus LS 600h L luxury sedan was the first vehicle to bring fuel-efficient gasoline-electric hybrid technology to the prestige luxury segment. The Lexus LS 600h L provides the brand's highest level of performance and technology, and the truest expression of luxury.
The Engine/Transmission/Drivetrain/Performance
The Lexus LS 600h L is powered by the ultra-quiet Lexus Hybrid Drive system, which was the world's first to combine a V8 gasoline engine with an all-wheel-drive (AWD) hybrid drivetrain. The system combines a 5.0-liter V8 gasoline engine with two powerful electric motors and a large-capacity battery pack.
The hybrid powertrain generates a peak combined output rating of 438 horsepower and can effortlessly accelerate the Lexus LS 600h L from zero-to-60 mph in just 5.5 seconds. Mid-range acceleration is even more impressive. The electric motor system is capable of delivering maximum torque on demand and is most beneficial during passing maneuvers. The Lexus LS 600h L can accelerate from 50-70 mph in a rapid 3.5 seconds. Its combined EPA fuel economy rating of 21 mpg is equal to or better than the combined fuel-economy ratings of some V6 all-wheel-drive mid-sized luxury sedans.
The innovative V8 features an electric motor-driven Variable Valve Timing with intelligence and Electrically controlled intake cam (VVT-iE). This combination of VVT-i with electric-motor driven intake and an oil controlled VVT-I exhaust system achieves superior engine-startup operation and high-output performance. The specially developed Hydrocarbon Adsorber and Catalyst (HCAC) system is linked to the two-way exhaust to help prevent hydrocarbons contained in the exhaust from being released into the atmosphere during cold start up when the catalysts are not up to temperature.
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.
