What's New for 2008

For the 2008 Lexus IS 350, a handful of minor changes take place, including a new "Liquid Graphite" finish for the wheels, recalibrated steering for better feel, a new coin holder and revised front seatbacks that provide more rear legroom.


Earlier this decade, Lexus decided to try its hand in the ultra-competitive compact sport sedan segment by introducing the rear-wheel-drive IS. But as most folks know, squaring off against the perennial champ, the BMW 3 Series, is like stepping onto a tennis court and seeing Roger Federer waiting for you on the other side.

The IS 300 was a solid performer with sharp reflexes, but it wasn't really a threat to the benchmark Bimmer. Its lackluster cabin was more glorified Toyota than true Lexus, and its shortage of legroom in back didn't help matters either.

A couple of years ago, Lexus improved its ranking by replacing the IS 300 with the IS 350. More luxurious and more sporting than their predecessor, the 350 and its less powerful 250 twin are pretty much identical except for their V6 engines. As one might surmise, the IS 350 has a larger, more powerful engine. Either way, the cabin in the IS is a model of refinement and classy design, while most cutting-edge luxury features are either standard or optional.

For the 2008 Lexus IS 350, a handful of changes take place, such as a new "Liquid Graphite" finish for the wheels, recalibrated steering for better feel and revised front seatbacks to allow more rear legroom. Still, don't expect the IS to challenge a Maybach any time soon.

Being a member of Lexus' dedicated sport sedan line, the IS 350 packs a sophisticated suspension, powerful brakes and a ripping, 306-hp V6 under its neatly tailored sheet metal. From a performance standpoint, the IS 350 simply rocks -- it sprints to 60 in 5.6 seconds, sticks in the corners like a cat to a screen door and stops in short order.

In addition to facing the BMW 335i, the 2008 Lexus IS 350 slugs it out with other top entry-level luxury sport sedans like the Audi A4, Cadillac CTS and Infiniti G35. It's pretty much a toss-up except for the Bimmer, which noses ahead of the pack in acceleration and the more esoteric areas of chassis response and driving enjoyment. In reality, it's hard to go wrong with any of these great machines. With its athletic moves, generous features list and impressive overall quality and reliability record, the IS 350 is one of our top choices, and sport sedan shoppers should definitely give it strong consideration.

Body Styles, Trim Levels, and Options

The 2008 Lexus IS 350 is a compact luxury sport sedan. Available in a single trim level, its standard features include 17-inch wheels, a sunroof, leather seating, power front seats, automatic dual-zone climate control and a premium audio system with a six-disc CD changer and an auxiliary audio jack.

Optional features (mostly offered through packages) include heated and ventilated front seats, memory function for the driver and passenger seat, adaptive bi-xenon HID headlights, a power rear sunshade, 18-inch wheels and rain-sensing wipers. Also available are a navigation system, a Mark Levinson surround-sound audio system, satellite radio, Bluetooth connectivity, active cruise control, parking assist and a sport-tuned suspension.

Powertrains and Performance

A 3.5-liter V6 that makes an impressive 306 hp and 277 pound-feet of torque drives the rear wheels. The sole transmission choice is a six-speed automatic with paddle shifters. The IS 350 accelerates with the verve of a sports car, as zero to 60 mph takes just 5.6 seconds. Although the transmission offers quick manual-style gearchanges, it doesn't match revs on downshifts like some of its rivals' automatics do.

Revised fuel economy for 2008 is 19 mpg city and 25 mpg highway, which is on par with the rest of this class.


Antilock disc brakes, traction control, stability control and a full complement of airbags (including front-seat side and full side curtain) are all standard. Optional is a pre-collision system (PCS). PCS comes packaged with Dynamic Radar Cruise Control, which uses the radar sensor to detect obstacles in front of the car. If the computer determines that a collision is unavoidable, it pre-emptively stiffens the suspension, retracts the front seatbelts and pre-initializes brake assist so full braking is applied the instant the brake pedal is depressed.

In Insurance Institute for Highway Safety crash testing, the IS earned the best-possible rating of "Good" for its performance in both frontal offset and side-impact tests.

Interior Design and Special Features

The 2008 Lexus IS 350 boasts impressive interior materials, an attractive cabin design and plenty of luxury amenities. Everything from the wood-tone and metallic accents to the supple leather upholstery exudes high quality. Lexus also offers one of the best electronics interfaces in the luxury game, with easy-to-use controls. The optional navigation system and accompanying touchscreen are particularly friendly.

Most small luxury sport sedans' rear seating isn't exactly palatial, but this is particularly true with the IS 350. Even with this year's marginal improvement in legroom (that comes via scooped-out front seatbacks), adults or even large children may not be happy in the rear seat on long road trips -- especially with a taller driver up front. Headroom is also in short supply in both the front and rear. If you're at all above average in size, the IS may prove to be no more spacious than a luxury coupe.

Driving Impressions

With more than 300 hp, a finely tuned chassis and spectacular brakes, the IS 350 is an undeniable performance car. There's no discernible exhaust note, so don't expect aural delight, but the IS 350 effortlessly leaps to speed. The chassis is buttoned down, grip is impressive and although there isn't a manual transmission, at least the automatic's paddles add some involvement to the driving experience. Though steering feel is somewhat lacking, the action is laser-beam precise, making it easy to choose and hold a line through the curves. Should the standard chassis setup still not be enough, die-hard enthusiasts may opt for the optional X Package that includes a sport-tuned suspension and 18-inch summer tires.

This car is beyond words. I just purchased this car and I can not stop driving this thing. It is my first luxury sports sedan and first car I am owning. I have to say I am very impressed with the overall quality of this car. It is 4 years old now (2008 model) but shows terrific condition and durability. The car has a stunning look and turns heads everywhere I go. The interior is Lexus quality at its finest. They put top notch materials in this car and the cabin is a pleasure to be in. Waking up every morning to this car is like a dream come true. Get this car you will not regret it!

Traded in a ES350 and although it was a wonderful car, it didn't feel like it was MY personal car. The IS350 gives you that personal car feel and it is super fast and comfortable. I have yet to see another one in the city which also makes you feel special. Wonderful automobile with comfort and style.

Great sports sedan

Vehicle: 2008 Lexus IS 350 4dr Sedan (3.5L 6cyl 6A)

Pros/Likes: Very silent, smooth V6 engine, powerful acceleration and pulls hard beyond 4000rpm, excellent brakes, bulletproof electrics, excellent base sound-system, vented heated seats great in summer, soft plastics are a pleasure to the touch, nice LED lighting ambiance inside. Absolutely nothing like a regular Toyota (even though people love to say Lexus are overpriced Toyota... NOT). Cons/dislikes: Too silent for my tastes (needs a BMW like I6 grunt), awkward position of clock, tripmeter odo is not separate, navigation takes time to get used to, very limited headroom (I'm 5'9" and my head brushes the headliner with the seat all the way flat).

Great car

Vehicle: 2008 Lexus IS 350 4dr Sedan (3.5L 6cyl 6A)

Bottom Line- Ultimate compromise between sport and luxury. Very quick, smooth, glides over nicks and crannies in the road. I spend plenty of time on the road- love the silent ride! On the contrary, when the pedal hits the mat, the engine makes an extremely defined roar. Comfortable as hell up front, not so in the back. If I was at the track every day, 335i would be my choice. If I needed a car that would accommodate my daily driving with comfort and performance- no brainer- IS350. Excellent Audio.

Very fine vehicle

Vehicle: 2008 Lexus IS 350 4dr Sedan (3.5L 6cyl 6A)

I just bought a 2008 loaded Lexus IS350 w/7,000 miles...this is my 5th Lexus, the others being SUV's, but have also owned 3 BMW's, including a wonderful M3. The IS350 is a great car. 98% of my driving is city, suburb or highway and it performs flawlessly. If I drove major "twisties" everyday, maybe I would have bought another BMW, but few of us have the "true" abilities to push either Lexus or BMW to their honest limits... It has 90% of the BMW capabilities, IMHO, plus a quieter ride, better interior, better exterior, more reliability and at least an equal resale value. It doesn't scream "look at me"...hey, even the engine and muffler are quiet, but power is vastly available when you want it.

My is-350

I love my IS-350. It is fun to drive, comfortable, great looking and handles nicely. The prompt response when needed or wanted is awesome when slipping into manual trans mode. Nav system is to be desired. It has some good points and I used it on several occasions to find my way but the voice recognition is worthless. Audio system is OK but it would be nice to see the track name and not just a number on CDs. Limited rear seat leg room could be a problem but I seldom use it so I deal with it. Memory front seats should be standard, after all, this is a Lexus.

I am on the market for a new IS 250 BUT I am not sure if I should wait for a couple of months and get a 2008 model or use the fact that 2008 is on the market so that I can get a deeper discount on 20?...

I am considering changing the air intake on my 2008 IS 350, will this void the warranty. Any thoughts on this?...

Searching the internet recently and found these photo's of the next generation RX. It looks like production will begin in late December 2008 with sales beginning in early Spring 2009.....
