The second-generation IS was introduced at the Geneva Motor Show in March 2005 as a pre-production model, with the production version debuting at the 2005 New York Auto Show that April. Sales began worldwide in September and October 2005 as a 2006 model. with the Toyota Altezza name ceased to be used with the introduction of the Lexus division in Japan, and the slow-selling SportCross station wagon version was dropped from the lineup altogether.
In North America, IS models sold at launch included the IS 250 and IS 350 sedans; in parts of Europe, the IS models sold by Lexus included the IS 250 and IS 220d sedans. The IS 250 was also available in Australia, New Zealand, Thailand, Singapore, Hong Kong, Chile (automatic only), Taiwan, South Africa and South Korea.
On 6 December 2006, Lexus officially confirmed the existence of a high-performance variant of the second generation IS called the IS F. The Lexus IS F sedan (USE20) premiered at the 2007 North American International Auto Show on January 8, 2007 as the launch product of Lexus' F marque lineup of performance-focused vehicles. The IS F went on sale several months later in North America and Europe. The IS F was capable of 0–60 mph (0–97 km/h) in 4.6 seconds, and had a top speed of 170 mph (270 km/h) (electronically limited).
The introduction of the second generation IS model marked a resurgence in sales for the IS line, with a 332 percent increase overall in 2006 compared to the previous year. In its first year of sales, the IS sold over 49,000 units, making it one of the ten best-selling luxury cars in the U.S. The IS line later took a median position in the entry-luxury market; in 2008 it sold behind the variants of the BMW 3 Series, new Mercedes-Benz C-Class, and Cadillac CTS, and ahead of the Acura TL, Audi A4, and Infiniti G35 sedan. Outside the U.S., the Lexus IS spearheaded Lexus' growing sales efforts in Europe, Australia, and South Africa, becoming the best-selling model in Lexus' lineup in many of the aforementioned markets. In the U.S., as of 2011, the Lexus IS was the third place best-selling vehicle from the marque after the Lexus RX and Lexus ES.
All second generation IS models offered a more typical Lexus interior compared to the previous generation with a focus on luxurious accouterments. The interior featured memory leather seats, lightsaber-like electroluminescent instrument display lighting and LED interior lighting accents, the choice of faux-metallic or optional Bird's Eye Maple wood trim (aluminum composite on the IS F), and SmartAccess keyless entry with push-button start. Options ranged from touchscreen navigation with backup camera to a Mark Levinson premium sound system and Dynamic Radar Cruise Control.
In 2009, the IS line received a styling refresh, and the suspension and steering were retuned for improved stability and control. After three years with only one body style, the IS returned with a second body style, this time as a hardtop convertible, on 2 October 2008 when the IS 250 C debuted at the Paris Motor Show. A more powerful IS 350 C also became available, with engine specifications analogous to those on the sedan models. The IS convertible went on sale in Europe in 2009, in North America in May 2009,[ and an IS 300 C was also produced for certain regions. The mid-cycle refresh in 2009 saw slight styling revisions to the interior.
In 2010, coinciding with the second IS line refresh, the diesel IS 220d was detuned with improved fuel consumption figures but lower power output by 27 bhp (20 kW; 27 PS). The addition was called the IS 200dBuilding on its "F Sport" line of parts and accessories for the IS 250/350, Lexus added factory-produced F Sport IS models in 2010. The second refresh also include further interior updates for the IS line.
Safety features on the IS models ranged from multiple airbags to stability control systems. A Pre-Collision System (PCS) was the first offered in the entry-luxury performance sedan market segment. NHTSA crash test results rated the second generation IS the maximum five stars in the Side Driver and Rollover categories, and four stars in the Frontal Driver, Frontal Passenger, and Side Rear Passenger categories; Insurance Institute for Highway Safety scores were "Good" overall score for all fourteen measured categories in the front and side impact crash tests.
The second generation IS marked the next introduction of Lexus' new L-finesse design philosophy on a production vehicle, following the premiere of the 2006 Lexus GS performance sedan. The sedan's exterior design featured sleeker, coupe-like contours, a fastback profile, and a repeated arrowhead motif in the front fascia and side windows.The IS sedans carried a 0.28 Cd figure. The forward design was reminiscent of the earlier Lexus LF-C convertible coupe concept.
History of development
After commencement of U.S. sales of the XE10 in 2000, development begun on its successor, the XE20 under chief engineer Suguya Fukusato in 2001. Design work was done under Kengo Matsumoto for a period of 2 years from 2002 into late 2003 when the final conceptual design by Hiroyuki Tada, utilizing the new corporate styling theme of L-finesse was chosen. From late 2003 into mid-2004, the conceptual design was further refined into the production design specifications, being then approved by the executive board.Design patents were filed in September 2004 in Japan, on February 18, 2005 in Europe, and February 25, 2005 at the United States Patent Office upon conclusion of development in early 2005.
Exterior and interior
The second generation Lexus IS was the second debut of Lexus' new L-finesse design philosophy on a production vehicle, following the premiere of the 2006 Lexus GS performance sedan. The new IS design featured sleeker, coupe-like contours, a fastback profile, and a repeated arrowhead motif in the front fascia and side windows based on the Japanese concept of kirikaeshi, referring to angular movements. The forward design was reminiscent of the earlier Lexus LF-C coupe concept. Compared to its predecessor, the second generation IS was 3.5 inches (89 mm) longer and nearly 3 inches (76 mm) wider, largely due to a 2.3 inches (58 mm) wheelbase stretch. The grille was set at a lower level than the headlights. The new IS body resulted in a 0.28 Cd figure.
The second generation IS interior features leather seats, lightsaber-like electroluminescent instrument display lighting and LED interior lighting accents, 10-way (including lumbar) driver and front passenger power seats, and the choice of faux-metallic or optional Bird's Eye Maple wood grain trim made by Yamaha piano craftsmen from sustainable plantations. The interior design also derived elements from Japanese concepts, including hazushi, where an object retains individuality while being part of a large whole, as typified in side air vents. Other available interior features include perforated leather seats, heated and ventilated front seats, power tilt/telescoping steering wheel, moonroof, electrochromic side view mirrors, power rear sunshade, and aluminum scuff plates.
The Lexus IS features standard dual front airbags, front row knee airbags, front and rear side curtain airbags, and front side torso airbags. The new IS also debuted its manufacturer's latest twin-chamber, V-shaped front passenger airbag. Initially, the IS 250 came with the Vehicle Stability Control (VSC)] system while the IS 350 used a more advanced VDIM system which reacts sooner with less intrusive operation. A Pre-Collision System (PCS) is the first offered in the entry-luxury performance sedan market segment.
National Highway Traffic Safety Administration (NHTSA) crash test results in 2008 rated the IS the maximum five stars in the Side Driver and Rollover categories, and four stars in the Frontal Driver, Frontal Passenger, and Side Rear Passenger categories. Euro NCAP scores were the maximum five stars in Adult Occupant, four stars in Child Occupant, and two of four stars in Pedestrian test categories. The Insurance Institute for Highway Safety gives the Lexus IS sedan a "Good" overall score for both front and side impact tests, and also ranks the IS "Good" in all fourteen measured categories in the front and side impact crash tests.
For the IS 250, IS 350, and IS F, engines feature the manufacturer's D-4S direct injection system; these models are ULEV-II emission certified in the United States by the California Air Resources Board. The IS line also features an Electric Power Steering (EPS) system which replaces the previous hydraulic steering pump.
Technical features on the second generation Lexus IS further include rain-sensing wipers, Intuitive Park Assist (IPA), bi-xenon headlamps, Adaptive Front-lighting System (AFS), and Dynamic Radar Cruise Control. Lexus' SmartAccess keyless entry with push-button start is a standard feature along with a memory system that can recall driver's seat, side mirror, and steering positions. A high-resolution 7" touchscreen DVD-based Gen V navigation system with voice recognition, Bluetooth, a backup camera, and a 14-speaker Mark Levinson premium sound system are available as options.

GSE20 / GSE21 (2005)
The IS 250 (GSE20) went on sale in 2005 in Japan and North America in RWD (GSE20) and IS 250 AWD (GSE25) configuration, along with the more powerful rear-wheel drive IS 350 (GSE21) sedan. The IS 250 RWD comes standard with a 6-speed manual transmission, and a 6-speed automatic transmission is available as an option. All other gasoline-powered IS sedans are only available with the automatic.
The IS 350 shares larger braking discs and calipers borrowed from the GS 430; the IS 350's larger calipers are four-piston rather than the two-piston front calipers of the IS 250.
Citing independent testing by auto research firm AMCI, Lexus highlighted the IS 350's acceleration as the "fastest in its class" at its launch (see also: Lexus IS performance specifications). Some reviewers noted the second generation models as Lexus' first foray into the sport compact market that compared fairly well with its German competitors. However, some criticisms were that its steering was not as communicative as that of some rivals, the rear seat legroom (while improved over the first generation) was still tight, and that the six-speed manual was only available on the IS 250. However, the IS' performance has also been praised, for example in a February 2007 Road & Track Japanese luxury sports sedan comparison, in which the IS 350 took first place.
ALE20 / GSE22 (2006)
Introduced for sale in European markets in 2006, the IS 220d (ALE20) was the first diesel-powered Lexus ever produced. The IS 220d featured a 2.2 L 2AD-FHV Inline-4 diesel engine, capable of 175 hp (130 kW), and rear wheel drive. The IS 220d was only offered with a manual transmission. Introduced to Chinese and Middle Eastern markets in 2006, the IS 300 (GSE22) was tailored to the fuel requirements of those regions, with a 3.0 L 3GR-FE V6 engine (without direct injection), 228 hp (170 kW), and rear wheel drive. The IS 300 was also introduced to the Brunei, Indonesia, and Philippines markets.
GSE20 / GSE21 (2008)
After three years with only one body style, the IS returned with a second body style, this time in hardtop convertible form, debuting as the IS 250 C on 2 October 2008 at the Paris Motor Show. A more powerful IS 350 C also became available, with engine specifications analogous to those on the sedan models.
The IS convertible features a three-piece aluminum hardtop that can retract in 21 seconds, a roof-brake mechanism slows panels as they close and near the windshield. The IS 250 C and IS 350 C are offered with a six-speed automatic, while the IS 250 C will also offer a manual transmission and all-wheel-drive version. The IS convertible's body carries a 0.29 Cd figure.
The IS 250 C went on sale in Europe in 2009, with IS convertible sales for North America targeted for May 2009 as a 2010 model. An IS 300 C is also being produced for certain regions.
In 2010, coinciding with the second IS line refresh, the IS 220d was replaced with the more efficient IS 200d, whose improved consumption figures were due to engine retuning.All-wheel drive options were also expanded besides the IS 250 AWD with the addition of the IS 350 AWD model in major markets.
F marque models
In 2006, several automotive publications reported on rumors of a higher performance variant of the IS being tested at various stages of development. Spy photos of such a vehicle being tested in Germany and California were published in several magazines and websites. Among these spy reports, several photos were shown of a heavily modified and camouflaged IS sedan at the Nürburgring test track in Germany along with other disguised Lexus test vehicles. The previous generation IS 430 prototype vehicle was indicative of future possibilities for the IS series, including the likelihood that a second generation high-performance IS model could come equipped with a V8 engine. It was rumored that there would be a coupe and a convertible version for a 2009 model, as well as a convertible version of the V8-powered IS.
On 6 December 2006, Lexus officially confirmed the existence of the vehicle which they called IS F in the press release. At the North American International Auto Show on January 8, 2007, the new IS F sedan was debuted to the public along with the LF-A supercar concept. Images were leaked a couple of hours before the official announcement. At its press debut, Lexus revealed that a separate "skunk works" team designed the IS F in a manner distinct from typical Lexus engineering efforts. The chief designer of the IS F, Yukihiko Yaguchi, previously worked on the Toyota Supra. Much of the IS F's suspension tuning took place at Fuji Speedway in Japan.
The IS F vehicle body was lowered by 1 cm (0.5 inches) compared to the standard IS. The hood features a bulged appearance, with sharper curve than the standard IS, due to the added space needed to contain the 5.0 L V8 engine. The drag coefficient is 0.30 Cd. The exterior also features a wire-mesh grille, changed side fenders and skirts, along with side air vents. One noticeable element of the IS F design were its faux quad exhaust tailpipes consisting of two vertically stacked exhaust tips on each side that did not directly connect to the actual exhaust pipes ( tips were part of the bumper, rather than the exhaust). The interior features a four-passenger cabin with braided aluminum panels, steering wheel paddle shifters, and F marque emblems. The IS F also features different seating, with bucket seats in front and rear.
The Lexus IS F features a 5.0 L direct-injected 2UR-GSE V8 producing 416 SAE hp (423 PS, 311 kW) at 6600 rpm, while peak torque is 371 lb·ft (503 N·m) at 5200 rpm. The engine redlines at 6800 rpm and also features a two-stage intake system, engine oil and automatic transmission fluid coolers and an oil pump designed for high-speed cornering. Along with both port and direct injection, the engine features VVT-iE camshaft timing, and has a compression ratio of 11.8:1The 2UR-GSE is derived from the Lexus UR-series V8 engines, which first debuted as the 1UR-FSE on the 2007 Lexus LS 460. Of the UR-series V8s, the 2UR-GSE is most closely related to the 2UR-FSE used in the 2008 LS 600h. It features the same bore and stroke dimensions (3.70 in x 3.52). However, extensive modifications carried out by the IS F engineering team in conjunction with Yamaha's Formula One (F1) engine program resulted in a cast-aluminum intake manifold, new cylinder heads, and titanium intake valves. Additionally the engine features a forged crankshaft, connecting rods and cam lobes. At maximum acceleration above 3400 rpm, the secondary intake opens Compared with the LS 600h's 2UR-FSE (measured alone without its hybrid-electric motors), the IS F 2UR-GSE has more horsepower and torque at higher rpm, and 17 lb·ft less peak torque (see also Lexus IS F performance specifications)
The Lexus IS F features an 8-speed Sport Direct Shift (SPDS) automatic transmission with sequential shift which can lock-up the torque converter from 2nd through 8th gears (see also: Lexus IS transmission specifications). The SPDS is derived from the unit introduced in the 2007 Lexus LS, which was the first vehicle to carry an 8-speed transmission. The SPDS allows for shifts to occur in 0.1 s (100 ms),to 0.05 s (50 ms) of F1 race cars.The wheel-mounted paddle shifters allow for gear shifting while steering, and a manual mode can be selected for added control. The 8-speed transmission also improves fuel economy with lower overall consumption than BMW, Mercedes, and Audi rivals, and avoidance of the U.S. Gas Guzzler Tax.
The IS F uses an all-electric rack and pinion steering system with a 13.6:1 gear ratio. The drivetrain is linked to a new sport version of Lexus' electronic stability control system (Vehicle Dynamics Integrated Management, or VDIM, featuring three distinct on-off modes).The Lexus IS F comes equipped with Brembo cross-drilled brake rotors (14.2 in front, 13.6 rear) and 6-piston front and 2-piston rear aluminum calipers stamped with the Lexus emblem, along with 19-inch BBS forged aluminum alloy wheels.
In October 2007, the IS F premiered in Japan, with a 500-unit yearly target for that country, and a 5,000–6,000 yearly unit target for the U.S. market. Top speed was listed at 168 mph (270 km/h). The IS F went on sale in the US in early 2008 with the first 50 IS F units sold as a limited Neiman Marcus special edition. In 2007, the head of Lexus GB stated in an interview that 150 IS Fs would be allocated for the UK market. For 2008, the IS F carried a base price of US$56,000.
For 2010, the IS F added a Torsen limited-slip differential, standard iPod/USB connectivity, Bluetooth streaming audio capability, casual language voice commands, and standard XM Satellite Radio. For the 2011 model year the electric power steering system and suspension were revised, with tweaks to the front and rear spring rates, shock absorber dampening, rear bushings and rear camber angle. An interior update included the addition of the Sport button to the steering wheel and a redesign of the gauge cluster featuring a large central tachometer similar to the Lexus LFA. The exterior adds LED daytime running lights and according to Lexus the 2011 IS F can lap Fuji Speedway in 2 minutes, 3.4 seconds or nearly 2 seconds quicker than before.
Aftermarket tuners such as Wald and FiveAxis have produced special IS F models, which have been part of the manufacturer's auto show exhibits. In 2009, Humberside police, UK also acquired Lexus IS F models for police cruiser duty, following a 12-month period of testing along with similar vehicles. The vehicles, selected for their performance chassis and electronic platform capabilities, were named IS-Force models.
IS F Racing Concept (2008)
At the 2008 Tokyo Auto Salon, the IS F Racing Concept was shown. Few details were released at the show, other than that the concept was the work of chief engineer Yukihiko Yaguchi who built the concept "just for fun", to show "true driving pleasure", and exhibit a potential IS F race car. The IS F Racing Concept had larger fenders, wheels, and spoilers, in a similar manner as DTM racing cars. Reports at the event suggested that the vehicle was not planned for actual racing; rather instead different IS F models were being prepared for racing.The IS F later made its racing debut in VLN competition (see Lexus IS (XE20) in motorsport).
IS F Circuit Club Sports (2010)
It is a version of IS F sedan with a carbon fiber reinforced polymer hood, trunk and rear spoilers, along with a rear titanium muffler, 19-inch magnesium wheels, and modified suspension and brakes.
