First Drive Impression: Flagship Lexus LS460L




The spanking new Lexus showroom is indeed a 5-star hotel parading as a car showroom.

Customer service is impeccable with fine mannerism, courtesy and attentive service ruling the day.

Here is my brief impression with the LS460L because there was a long wait-list for the GS300 tester.

This luxury limousine is full of sheer presence, measuring at 5.15m in length, with an extended 3,090mm wheelbase. Powering it is a 32V DOHC V8 with Dual-VVTi displacing 4,608 cc. Power output is rated at 380bhp @ 6,400rpm and torque is a bolt-wrenching 493Nm at 4,100rpm! All this glory is neatly nestled under super-clean engine covers. I dare challenge anyone to find a single wire dangling upon popping up the hood.

Check out the engine bay!

Before we drove off, our sales consultant, Tareq demonstrated the 16-speakers Mark Levinson DVD-CD-Radio system. It was mind-blowing for an in-car entertainment system to reproduce such clean, uncluttered and balanced sound! Capable of dts and Dolby-Digital 5.1 in all its glory!

Most striking impression of this flagship Lexus must be its baffling silence. The LS460L is so refined you don�t even hear its engine idle. Outside noises are practically filtered out while rolling tyre noises are almost absent. The V8 is simply marvelous with a linearity of power that attests to the clich� saying: �No replacement for displacement.�

Prod the throttle and you get creamy smooth acceleration and pick-up capable of hauling this 2 tonne beast in 5.7 secs to the century sprint.

Tackling those rough speed strips on the highway was as if they were non-existent. In similar fashion, all lumps and bumps plus nasty road irregularities are effectively dampened. Steering felt light and lifeless at high speed but what the heck�I guess such a limo was meant more for the chauffeur! Ride comfort is carpet-like even though air suspension was not part of the deal here.

Pushing the car into high three digits speed was a breeze. Due credit to Lexus for the superb 8-speed auto �box which is very smooth, with truly imperceptible upshifts and downshifts - even in manual mode. However, care must be taken for a LWB car like this because it oversteers easily and the rear end felt floaty and twitchy at times. Tracking stability in those fast sweeping corners is a little lacking � a dark blot marring its otherwise pleasant chassis dynamics. Braking power is excellent and pedal feel is good.

So how does this super-limousine bred from �The Pursuit of Perfection� rate in the company of the new W221 S-Class and the current 7-series?

Towards this, I can only say: �The backseat is the best place to be in�.

Fasten Your Seat Belts, It's the Porsche World Roadshow 2007 - part 1






PORSCHE�A seven-letter word synonymous with high performance sports cars. From the iconic 911 to its latest Cayman S, this German automotive company has inspired � as well as fulfilled - many dreams and aspirations since 1948, all around the globe.

The Porsche World Roadshow was last held at Sepang in 2003 and now 4 years later, I had booked a �privilege� seat to sample the variety of Porsches up for testing and also understand a little more of the chassis dynamics unique to this well-known brand. Some advance driving techniques incorporated into the day�s programme proved valuable as we get to take the cars to the limits in a couple of simulated emergencies.

The day started off early at 8.30am with us checking in at Sepang F1 circuit. With the sun just dawning up the horizon, it was really a sight to behold, seeing the many variants of Boxsters, Caymans, 911s and Cayennes all lined up at the pit entrance to greet us.
After registration and breakfast, the welcome address was helmed by Auto Eurokars� CEO, Allan Pillai. We were introduced to the five instructors namely Arnd Stollman (Chief Instructor), Sebastian, Matthias, Tommy Lee and Tengku Djan. Thereafter, we were split into 5 groups: Red, Yellow, Blue, White and Green - with similarly shaded collar bands to match!

All groups were briefed on the correct seating/driving position by Matthias with concurrent in-car demonstration by Sebastian.
Some of the notable pointers here include:
1) NEVER hold the steering with both arms fully stretched out. Placement of both forearms should reach the top rim of the steering wheel at the wrist flexures. As such, the elbows should be bent and arms relaxed when you hold at 9 and 3 o�clock positions. These would enable better steering control.
2) The knees must remain slightly bent with the brake pedal fully depressed. Such limbs positioning enables a more forceful �kick� of the pedal in emergency braking. It also reduces the risk of crushing orthopedic injuries to the lower limbs and joints should there be an intrusive crash into the foot well.
3) The driver�s seat should be as vertically comfortable as can be. So as to enable good support � both at shoulders and flanks � into corners as well as to provide proper backrest support should an accident occurs.
4) Last but definitely not the least - the most basic but important safety aspect of all: Buckle up before you drive!

That taken care off, my Red group headed by Mr. Stollman headed for�no, not the track�but off-road. Thank goodness I skipped the heavy nasi lemak of the buffet spread! After a briefing on low gearings (Gear Reduction in Porsche speak) and highest suspension setting, we took off in 2 Cayenne Turbos, 2 Cayenne V8s, and 2 Cayenne V6s to the Sepang Off-road �track�. Never dreaming that we�d be able to do things like steep hill ascent and descent, lateral 30degrees slopes tilt and SUPER-sized multiple potholes in a luxury SUV like the Cayenne � all in reasonable comfort - we came away suitably impressed! This exercise demonstrated the Cayenne�s impressive 4-wheel drive capabilities on rough terrain.


Next up was the much anticipated Slalom event. With a quick briefing on how to tackle the many confusing cones, we have a Cayman S to snake around in this �converted� parking lot. I found myself somewhat like in an episode of �Fear Factor� because our runs will be timed. Hence, I had waited for many others in my group to go first just to familiarize better. After a demo lap with Arnd in the car, we were allowed two laps each, in the wonderfully agile and well-balanced Cayman S. The trick to doing these is nice, smooth and slow around those little cones� not nailing them or licking them � for there would be a time penalty for such errors. Our group was second quickest for the day, losing just by 1/10th of a second. Darn!
Collectively, we had wished for more attempts to improve our skills and timings�if only there was one more Cayman S with the help of another supporting instructor!


After the invigorating slalom, we took out a mix of Cayman, Carreras, Boxsters on the road to Sepang, Nilai and Dengkil. With traffic police escort in a white Proton Waja patrol car, we were made to feel like royalty or VVIP for an hour, where we just drove almost unhindered while we broke speed limits � and no speeding tickets! I took a yellow Boxster S fitted with Porsche Ceramic Composite Brake (PCCB - in matching yellow brake calipers) and I have got to admit the braking performance and pedal feel is truly magical. My driving partner Mr. Peter Lee and I were initially taken aback by its 6-speed MANUAL gearbox but�Alas! It was actually great to shift through the gears to truly savour the 295bhp and 340Nm of the 3.4litre boxer engine. Even in 5th gear and with the mid-engined motor spinning above 4000rpm, this lovely roadster was ever willing to overtake the Carrera 4S in front! But sadly, it was something banned during the Road Tour convoy but for the right safety reason. Tracking stability of this Porsche is superb, while the ride and handling composure were unruffled by the undulating road surfaces. The wind-in-the-hair feeling in a Boxster was really nice seeing that there was hardly any turbulence � nor excessive wind noise - even at 145km/h! Strange but pleasantly true even in topless mode. Hmmm�Must be all the hard work done by Porsche AG in the wind tunnel.

Lunch break was a sumptuous spread of Italian, Chinese and Western delicacies with the usual fruits and ice-cream desserts thrown in. We had a 45 minutes break before we were taken to the track (finally!) and this where I was shaken�by the menacing black 911 Turbo. Thinking I would ace this exercise since I had previously done it elsewhere in Audi A8L 6.0 W12 Quattro�I was shockingly WRONG! When Arnd took me for a demo lap, I was pinned to my seat when he suddenly rocketed from 40km/h onwards - the moment the twin-scroll turbo kicked in. It felt like I was riding a roller-coaster�on a down slope!
My heart percertibly dropped for that one second, not unlike the feeling of Space-Shot ride at Genting outdoor theme park. A fellow partner-in-crime attested to feeling his eyeballs pushed deeper into their sockets when the 997 Turbo blasted away. Gosh! Imagine a sports car capable of 3.7secs to 100km/h and an equally arresting (literally)�100-0 km/h in 2secs!!! Man, those PCCBs are really awesome.
The emergency braking manoeuvre demonstrated the beauty, logic and necessity of ABS, in avoiding an obstacle during hard braking and maintaining the ability to steer at the same time. Following this, we found ourselves inducing an oversteer i.e. the tail of the 997 Turbo going wide � upon sudden lift off of the accelerator after a brief but lightning quick period of hard acceleration into a right hand corner. Needless to say, with the guidance and instruction of our superb instructor, I was able to execute a counter-steering manoeuvre on my second attempt. We were told that Porsche Stability Management (ESP equivalent) intervenes later in this 911 Turbo because of the Sports Chrono Package Plus fitted. Tasted some drifting here and it was nice, cool and fun�no wonder it is something of a cult among the rear-engined 911 owners.

Following this was the Handling exercise. We hit the track soon after a brief lecture on cornering lines i.e. tips on entry and exiting an apex of a corner. Once again we were given a demo lap each by Arnd in another Cayman S. Thereafter we took two laps each in a Carrera S and Carrera 4S consecutively - where we found ourselves more confident around the bends with each subsequent lap - around this magnificent F1 track. Our understanding of a vehicle�s weight transfer upon throttle input, braking and steering input were revised and improved upon after this �racing� exercise.

It was then time for the final on-track programme where we were herded together again. Each participant could choose on a demo lap by any one of the instructor. This was where it got a little out of hand but more on this later. The outstanding vehicle here (apart from the later-included 911 Turbo) must be the Powerkit boosted Cayenne Turbo with 500bhp! Sounding like a growling beast, it had no sweat keeping up with the rest of the pack of Carreras, Targa and Cayman S. I had my ride with our Malaysian famed drifter Djan at the helm of a manual C4S�man, drifted like an insane person at the wheel he did!
One thing that marred this first day of this Malaysian leg of PWRS 2007 at Sepang must be the shameful �kiasu� attitude of my fellow delegates. Some of them can be seen jostling for Demo laps over and over again�up to 3-4times even - in succession - thereby displacing others who had not even got their well-deserved one-ride to each person. Imagine this happening at a premium event where everyone is paying the tune of RM2,200 each. C�mon, grow up guys and gals!

An award ceremony was held to present certificates and trophies to the winners. After this, we bade farewell to the Sepang F1 circuit�secretly hoping that one day we�d be able to rent, borrow or steal one of these magnificent machines.

The next leg of PWRS 2007 would be in Thailand in end January 2007, followed by in Singapore by end February 2007. The screeching and screaming tyres were sponsored by Michelin.

Civic Duty


Had the opportunity to test both cars back-to-back recently, courtesy of a major English daily.

Anyway, it was a mixed experience. Because beauty may be just skin deep for both these 8th gen Civics...

Having tested just the 1.8iVTEC during launch, I was naturally gunning for the 2.0S drive out of town. Well, it did drive very well. The K20A performed as expected of a Honda N/A modern engine with its famed i-VTEC, DOHC et all. The paddle shifters were pretty slick to execute, fun as well as functional to use in the twisties. Only gripe is its slightly teeny size (length-wise) and made of a tad softie of mildly malleable PLASTIC!

I started off with the entry-level 1.8S SOHC i-VTEC. Being a car that has chalked up considerable mileage - after having just completed its second scheduled service - I experienced it to be a little more refined and willing on the go. While it isn't underpowered, I found myself trailing the other 2.0S when we hit the trunk roads. As expected, the 1.8L powerplant was drumming quite a bit when I stretched it beyond 5000rpm. It just felt out-of-ooomph beyond this, like it hit a plateau of maximum output. Riding in the rear exposed a glaring NVH deficiency in the form of road/tyre roar.

I was gleefully smiling when I got the keys to the BIG brother next. True enough, the difference in initial drive was felt the moment I prod on the gas pedal. Throttle response was quicker and sweeter. Sweeping frequently all the way to redline was a joy and breeze through the gears.

The EPS steering may have felt a little light but I somehow felt it was sharper and more incisive. The 1.8 rack seemed a bit vague and wooden even tough its hydraulic weighting felt a bit nicer.

Ride and damping of both models are well sorted out. (But I don't think we should place them on par with one of the new BMWs!) Honda Motor Co. has actually got them quite right this time around for these mid-segment sedans. Handling and grip around the bends are good enough for the most of us but it's the paddles-enabled manual shifting that tips the 2.0S towards a higher level of road-holding forte over the 1.8S. All said, I still think the new Focus has a more coherent performance in the HANDLING department.

Now, why is that all this beauty - in the form of aesthetics and an overall good drive - may be just skin deep?

One word: QUALITY.

In this age of cost-cutting, out-sourcing and foreign-country manufacturing base et all, Honda Motor Co. has actually neglected certain build and quality aspects of these Civics...

Some steel sheets are glaringly thin, especially in the doors. Tugging the rear outer door handle caused a 'ripple' vibration on this door�s outer metal sheath. As such, a resultant tinny closing sound can also be heard. The windows' outer lower horizontal frame seemed to flex very easily with the window wound-down. I was also shocked to find that the rear speaker shelf is of hard (but grain-textured) plastic. Whatever happened to good old soft-carpeted or veneered parcel board?

I have a gut feeling that the roof maybe quite noisy in the rain as well since it was quite tinny on percussion as well.

Door sill plates were 'mysteriously' absent too, even on the premium 2.0S! To a certain extent - quality-wise - both Civics reminded me much of my wife's 'budget' Honda City...

Whatever said, the waiting list of the Civics are getting longer by the day, more so for the 2.0S after the NAP 'discounts' and HM 'superb' production planning in Pegoh, Melaka.

Overall, it's a good car and likely a benchmark "all-rounder" in its segment, until the next all-new Corolla in 2007 challenges it all over again...

Audi A4 TFSI - To Quattro or Not to Quattro?



Normally two-wheel drive cars, either FWD or RWD, have accelerative forces handled by just two wheels. Apart from this forward driving force, these pair of wheels also has to tackle cornering and braking forces. As such, it�s easy to see that all these forces can easily overwhelm its grip limit, especially at high speed around corners while accelerating away. All-wheel-drive system like Audi�s Quattro system distributes the engine�s torque to all FOUR wheels, thereby apportioning the accelerative forces by 50% lesser on each tyre. As a result, each wheel gets a higher reserve for handling �extra� cornering forces before losing grip and start screeching.

Well, the above law of physics applies to the Audi 2.0TFSI Quattro as well.
This is my take on the car after having spent a weekend with it�

The first thing that strikes you when driving off in this Quattro is that this A4 is noticeably less hurried on the go. My feeling is that it may be a second or so slower to the century dash. Overtaking times felt laggardly slower too. But all is not lost since the drive seemed more �civilized� with none of the CVT start-lag of its multitronic sibling. Apart from this, the ride and damping of this Audi came across as definitely more pliant and comfortable � somewhat baffling since we would have expected this higher performance Quattro version to have harder suspension settings. There was hardly any lateral sway on cornering � a trait so evident in most two wheels driven cars. No hint of understeer even upon hard driving on winding coastal roads. Alright, alright�maybe just some front tyres� squeal! With the Quattro driveline putting some more weight and drive towards the rear, this sedan somehow feedback as being more balanced. Grip levels were phenomenal with its permanent 4WD mode. Road hugging abilities on hilly B-roads is so excellent that I found it �strange� taking some cornering lines that I normally take in my usual rides, at higher speed without breaking a sweat . Handling would be naturally superlative too if not for the strangely light and vague steering feel � quite unnerving initially. However, as I got used to this undesirable rack �settings�, I began to accommodate reasonably well. Yet, I wished that the Audi engineers dialed in more feel and weight to the scheme of things here.

Manual gear changes weren�t as swiftly engaging as the multitronic�s 7-speeder. This is after all a 6-speed torque converter with �tiptronic� functions but I supposed I could live with marginally slower up-shifts of cogs, if I were to own this junior exec.
Braking performance is similar to the regular FWD sibling. Rotors bite seem just as reassuring but there were less of the disc-grabbing tendencies felt earlier in the other B7 TFSI multitronic. The brake pedal is placed a tad too high though, for smooth migration of your foot from the gas pedal. Some awkward �higher-lift-and-cross� pedals� action warranted here.

On the highways, I have got to admit that speed would build up quicker in the �plain� TFSI variant, with lower engine revs at any given expressway speed. Yup! I reckon that the multitronic CVT would be more efficient here. The Quattro is no slow coach but like I said before, just more mild mannered � due to the extra weight and the same 2.0 TFSI output of 200bhp and 280Nm driving the rear axle as well. In fact, the engine sounded quite hoarse (due to the �busier� driveline?) when stretched but then again maybe it�s just psychological. Breaching the speed limit also exposes some wind noise in this test car. Close examination of the door-window frames revealed a gaping rubber lining at the right B-pillar � corresponding to the rear window frame.

Having put in a few hundred kilometres over a couple of days, I had found the Quattro to be relatively frugal on fuel. In all fairness, I hardly drove the car in �S� mode this time around. Some of the noticeable bugbears of this A4 � upon closer scrutiny � are the somewhat soft and springy switches for power windows and also of the front reading lights. They felt flimsy and loose to operate, a letdown to the overall superb built quality of this Audi. I also wish for rear side storage pockets on the door trim, which are mysteriously absent for an automobile of this price.

Other than that, I guess it�s worth paying the RM15k premium over the �standard� TFSI multitronic. Not so much for the �quattro� badges� bragging right but for the extra refinements in ride, comfort, composure and power delivery. Heck! I was pleasantly surprised when my family attested to some of those attributes too over the test drive period. If only Audi AG reworked this award-winning 2.0 TFSI engine to churn out 261bhp and 350Nm, just like for its upcoming Audi S3, because this A4 Quattro�s drivetrain and chassis could definitely handle more!
