Lexus IS (XE20)

For a complete overview of all IS models, see Lexus IS.

The Lexus IS (XE20) is a car produced by the Japanese carmaker Toyota under its luxury division, Lexus. Classified as a compact executive car, it represented the second generation of the Lexus IS. Serving as Lexus's entry-level sedan from 2005 until production ended in 2013, Toyota manufactured the XE20 at the facility in Tahara, Aichi, and the Kyushu factory in Miyawaka, Fukuoka (until 2012). It was available as both a four-door sedan and a two-door coupe—the latter designated by a "C" at the end of their name (e.g., "IS 250 C").

PredecessorLexus IS (XE10)
Successor

The development of the XE20 began in 2001 under the direction of Suguya Fukusato—chief engineer of the project. Primarily designed by Kengo Matsumoto, a pre-production version of the IS debuted at the Geneva International Motor Show in March 2005, the production version of which debuted at the New York International Auto Show in April of the same year. Production of the IS officially began in September 2005 at both the Tahara and Miyawaka facilities. Lexus implemented a staged rollout of the XE20 variants, starting with the IS 250 and IS 350 in 2005. The IS 300 and IS 220d, the latter of which marked Lexus's first diesel model, followed in 2006. In 2010, the IS 220d was replaced by the IS 200d. Lexus also produced high-performance variants of the IS under the F marque, known as the IS F.

The XE20 shared its platform with the fourth generation of the LS and the second generation of the GS, both of which were also built at the facility in Tahara. While several minor updates have been made, the XE20 has undergone one major facelift; this update included a slightly revised front fascia, an interior refresh, and modifications to the suspension. The XE20 has been well-received by car critics, who have most praised its design and reliability. The car has received numerous accolades, including Ward's 10 Best Engines in both 2006 and 2007 for the IS 350 and Car's Performance Car of the Year for the IS F in 2008. Production of the XE20 ended at the Kyushu facility in 2012, while manufacture at the Tahara plant ended in the subsequent year. It was succeeded by the XE30 model, which began production in April 2013. The IS C remained in production until 2014 when it was replaced by the RC.

History of development

edit

Development

edit

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 2003 into the first half of 2004, the conceptual design was further refined into the production design specifications, being then approved by the executive board.[1] Design patents were filed in September 2004 in Japan, on 18 February 2005 in Europe, and 25 February 2005 at the United States Patent Office upon conclusion of development in early 2005.[2]

Exterior and interior

edit
 
2008 Lexus IS 250 (GSE20; U.S.)

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.[3] The new IS design featured sleeker, coupé-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.[4] The forward design was reminiscent of the earlier Lexus LF-C coupé 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.[3] 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.[5] 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.[6] 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.

Safety systems

edit
 
2008 Lexus IS 250 (GSE20; Europe)

The Lexus IS features standard dual front airbags, front row knee airbags, front and rear side curtain airbags, and front side torso airbags.[7] 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.[8] 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.[9] 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 other measured categories in the front and side impact crash tests but give it a "Poor" score for small overlap front.[10]

Technical features

edit

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.

 
2010–2011 Lexus IS 250 (GSE20R; Australia)

Updates

edit

In response to criticism regarding the lack of a stability/traction control disable switch on 2006 IS models, Lexus added a VDIM/VSC off switch for the 2007 model year. For 2006 IS models, the stability control system/traction control system can be disabled through non-conventional methods by using a code during engine start.[11]

In the 2007 IS models, in addition to the on/off switch for the traction-control system, Lexus added a roof-mounted shark-fin antenna in some markets. (The Australian delivered IS models did not receive the fin-style antenna until its first appearance on the IS F in 2008).[12][13] For 2008 models, the steering system was tweaked for improved steering feel and the rear seats were modified to improve rear room.

The 2008 mid-cycle refresh for the 2009 model year (designed by Takahiro Kanno in 2007) included revised interior and exterior styling, the suspension and steering was retuned for improved stability and control, and the IS 250 also gained VDIM as standard for the 2009 model year. In 2009, Masanari Sakae designed revisions to the IS Line, which were patent registered in November 2009 in Japan and 27 April 2010 in Europe. In the second quarter of 2010 (2011 MY), these new revisions were introduced, featuring a refreshed exterior with new wheels, LED daytime running lights, additional interior features, and dedicated IS F-Sport production models.[14]

Standard models

edit

GSE20 / GSE21 (2005)

edit

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.

 
2010–2011 Lexus IS 350 (GSE21; Australia)

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.[15]

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).[16] 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,[17] 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.[18]

ALE20 / GSE22 (2006)

edit
 
Lexus IS 220d (ALE20; Europe)

Introduced for sale in European markets in 2006, the IS 220d (ALE20) was the first diesel-powered Lexus ever produced.[19] 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.[20] The IS 300 was also introduced to the Brunei, Indonesia, and Philippines markets.

 
2010 IS 250 C (GSE20; U.S.)

GSE20 / GSE21 (2008)

edit

After three years with only one body style, the IS returned with a second body style, this time in coupé convertible form, debuting as the IS 250 C on 2 October 2008 at the Paris Motor Show.[21] 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 was offered a manual transmission and all-wheel-drive version. However, as of 2015, the IS C is only available as rear-wheel-drive. The IS convertible's body has a drag coefficient of Cd=0.29.

Sportier models of both trims are available in the form of the IS250 C F-Sport and IS350 F-Sport. As of 2015 these models are the only F-Sport Lexus's to be offered with a wide variety of performance options such as a "F-Sport Air Intake" and "F-Sport Sway Bars" but just like the other Lexus F-Sport models it is offered with a wide variety of wheel choices.

 
Lexus IS 250 C (GSE20R; Australia)

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.[21] An IS 300 C is also being produced for certain regions.

ALE20 (2010)

edit

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.[14] All-wheel drive options were also expanded besides the IS 250 AWD with the addition of the IS 350 AWD model in major markets.[22]

F marque models

edit

During 2005 and 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 coupé and a convertible version for a 2009 model, as well as a convertible version of the V8-powered IS.[23][24][25]

USE20 (2007)

edit
 
Lexus IS F (USE20; Australia)

In early 2004, just after the final XE20 design had been frozen for production, Lexus engineer Yukihiko Yaguchi, assembled a small team and on a limited budget began work on a higher performance IS. By the first half of 2005, XE20-body prototype mules with the 4.6L 1UR-FE V8 were spotted testing on the Nürburgring. These prototypes were nicknamed "IS 460" by the media. In late 2005, test mules were also spotted on the Nürburgring that were made using body panels from Toyota Crown Royals that were shortened by cutting out sections of the roof and rear doors.[26] The winning exterior design proposal by Hiroshi Okamato (supervised by chief IS designer Kengo Matsumoto), was finalized in 2005.[27][28]

On 6 December 2006, Lexus officially confirmed the existence of the vehicle which they called IS F in the press release.[29][30][note 1] At the North American International Auto Show on 8 January 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.[31] 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 engineer 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.[32] The hood features a bulged appearance, with sharper curve than the standard IS,[33] 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.[33] 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.[33]

 
The Lexus IS F engine and transmission

The Lexus IS F features a 4,969 cc (5.0 L; 303.2 cu in) direct-injected 2UR-GSE V8 producing SAE 310 kW (416 bhp; 421 PS) at 6600 rpm, while peak torque is 371 lb⋅ft (503 N⋅m) at 5200 rpm.[34] 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 11.8:1.[35] The 2UR-GSE is derived from the Lexus UR-series V8 engines, which 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).[35] 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.[35] Additionally the engine features a forged crankshaft, connecting rods and cam lobes. At maximum acceleration above 3400 rpm, the secondary intake opens.[36] 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).[35]

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.[37] The SPDS allows for shifts to occur in 0.1 s (100 ms),[38] compared to 0.05 s (50 ms) of F1 race cars.[39] 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,[40] with lower overall consumption than BMW, Mercedes, and Audi rivals,[38][40] and avoidance of the U.S. Gas Guzzler Tax.[41]

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).[42] 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.

 
2008 Lexus IS F interior (USE20; Japan)

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.[43] By the final model year in 2014, only approximately 11,500 units had been manufactured, with 5,118 sold in the U.S.[44] Top speed was listed at 168 mph (270 km/h).[44] 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.[45] For 2008, the IS F carried a base price of US$56,000.

For 2010, the IS F added a Torsen limited-slip differential,[46] standard iPod/USB connectivity, Bluetooth streaming audio capability, casual language voice commands, and standard XM Satellite Radio.[46] 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.[47] An interior update included the addition of the Sport button to the steering wheel[48] 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.[49]

Aftermarket tuners, such as Wald International[50] and FiveAxis, have produced special IS F models, which have been part of the manufacturer's auto show exhibits.

IS F Racing Concept (2008)

edit

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.[51] The IS F later made its racing debut in VLN competition (see Lexus IS (XE20) in motorsport).

Gaming

edit
 
Project Five Axis Lexus IS F

In March 2008, Atari released the freeware computer game, Lexus IS F Track Time.[102] The program was created in partnership with Lexus and based on the IS F production model specifications.[103] Designed by Image Space Incorporated (ISI) using their rFactor computer racing simulator software, the program allows users to configure and race the IS F. Three race courses are offered, namely Orchard Lake (an oval and road course), Toban Raceway (a road course), and Essington Park, Lienz (a mountain road and rally course).[103] The software incorporates artificial intelligence modeling of competing vehicles, and its physics engine simulates actual driving conditions.[104]

The race-prepped Lexus IS F which competed at the 24 Hours Nürburgring race in October 2009 carried a prototype of a "GPS-track day" unit co-developed by the Gran Turismo game designers and Lexus supplier Denso corporation. The unit allows a GPS recording of an actual track drive, which is then stored on a memory card. The recording can then be plugged into a PlayStation 3 where one can view a virtual recreation of the race, or compete against one's own race record.[105]

Production

edit

The second generation Lexus IS is produced in Tahara, Aichi, and Miyawaka, Fukuoka, Japan. In most markets sold, the IS has served as the compact member of the Lexus lineup, and it was the smallest Lexus model until the CT 200h.

Only 486 units of the Lexus IS F were sold in 2012.[106]
