Dawn Raid

The new Lexus GS F has wandered into the V8 super sedan den, where itís keen to run rings around a couple of hungry force-fed predators


V8 SHOOTOUT HSV GTS vs Mercedes-AMG C63 S vs Lexus GS F

It used to be simple.

In your traditional triple-header V8 comparison youíd have three large four-door sedans, heralding from either Australia or the Fatherland, each with a fuel-guzzling lump in the front feeding tyre-frying torque to the rear wheels. Thereíd be a manual if it was designed for keen drivers, or a torque converter slushbox if it had luxo leanings.

Things are very different in 2016. In todayís topsy-turvy world we have three different engine configurations (one of which claims to sip just I 8.6L/100km), three different transmissions and two different body sizes. And the only contender that conforms to the traditional automatic gearbox, naturally-aspirated V8 stereotype is Japanese!

And itís the Lexus GS F thatís the catalyst for this comparison. It impressed us at its local launch, but its pricing and performance leaves it in a bit of a no manís land in terms of rivals. As a full-size V8 sedan its obvious competitors are the BMW M5 and Mercedes- AMG E63, but its price ($148,800) and performance (351kW/530Nm; 0-100km/h 4.6sec) neatly align with models the next rung down.

As such, weíve decided to attack the Lexus from both sides to try and gain a clearer picture of where this bent-eight Bento box sits in the muscle car landscape.

The HSV GTS is about as good as full-size performance gets without spending crazy money (and even then itís pretty competitive) while Mercedes-AMGís latest C63

is the current benchmark if youíre looking to spend around $150,000 on a sports sedan.

Key to the C63ís appeal is the 4.0-litre twin-turbo V8 under its heavily ridged bonnet. Producing 375kW/700Nm, itís not so much an engine as a volcanic eruption, capable of turning the 265mm rear Michelin Pilot Super Sports into molten black lava at will. AMGís Race Start launch control program is an easy way to reel off 4.4-4.5sec 0-100km/h times, but the furious struggle it sets off between electronics and wheelspin feels like The Hulk is trying to escape from the C63ís conservative Bruce Banner exterior.

Walking the car off the line oh-so-gently Ė not as easy as it sounds thanks to the wet-clutch autoís hesitancy from a standstill Ė and feeding the power in smoothly proves more successful. Thereís a fair amount of axle tramp in first gear, but drive through it and the C63 slithers its way to 100km/h in 4.16sec before storming across the quarter mile mark in 12.23sec at 192.50km/h.

As much as we loved the old M156 atmo 6.2, this new force-fed M178 clearly moves the game on. With the turbos wedged inside the vee of the engine, boost builds quickly and that massive 700Nm torque peak gives the car insane levels of roll-on performance, 80-120km/h disappearing in just 2.2sec. Clearly no-one told AMG that turbos ruin a carís soundtrack, either, the 4.0-litre V8ís deep gurgle morphing into a fierce growl as revs build.

If anything, though, HSVís 6.2-litre supercharged V8 sounds even better. The choof as the exhaust valves open is pretty naff, but itís a dirty noise, full of aggression and pent-up rage. What exactly itís angry about is unclear, because this manual GTS is the fastest standard Aussie car weíve ever tested. After a number of 4.4sec 0-100km/h runs, a fluke of a launch and a crisp change into second nets 0-100km/h in 4.31sec and a 12.37sec quarter mile at 188.32km/h.

HSVís range-topper hasnít always felt its full 430kW, but with 7000 hard press kilometres under its Continentals, GTS-430 is a rocketship, hauling through the gears with ferocious enthusiasm. The Gen-F2 GTS is supposedly unchanged mechanically, but the gearbox in this car (and every other Gen-F2 or VF II product we try) feels particularly slick; quick changes are far less of a lottery now and, all other things being equal, saving a tenth or two on each shift would certainly explain the improvement in acceleration times.

Unfortunately for the Lexus, itís a distant third in such potent company. Lexus claims a competitive 4.6sec 0-100km/h time, but short of pulling all the panels off to drop a couple of hundred kilograms itís never going to do that. The fastest figures of

To focus on the numbers sells the GS F short, as the 5.0-litre V8 spins easily to its 7300rpm cutout

4.99sec and 13.09sec for the 0-100km/h and 0-400m respectively are achieved by simply mashing the throttle from rest with all the electronics off, but to focus purely on the numbers sells the GS F short.

Which is just as well, as it trails the C63 to 180km/h by a whopping 2.34sec.

The 5.0-litre V8 is a great engine, spinning easily to its 7300rpm cutout with a note that, while obviously synthetically enhanced, is a curiously pleasing mixture of smooth and raucous, like velvet sandpaper.

Selecting Sport mode is a must, as Normal has the eight-speed auto clamouring for a higher gear and anaesthetises the throttle into the bargain.

The engine/gearbox combo is an effective one. The autoís around town behaviour shames even the best dual-clutch, yet the shifts are quick and the eight tightly-stacked ratios make the most of the GS Fís relatively limited torque reserves. That may sound like an odd description for a 5.0-litre V8, but 530Nm (at a relatively high 4800rpm) just isnít enough to trouble 275mm rear Michelin Pilot Super Sports.

Itís unusual for a car like this to have more grip than grunt, but the result is you can drive the absolute ring off the GS F. The brakes are outstanding, the passive suspension provides excellent body control and with total confidence in the rear end itís simply a matter of waiting for the front to stick Ė there is a degree of push at the limit Ė and then flooring the throttle. The electrically-assisted steering isnít particularly fast, nor does it provide a whole lot of feel or feedback, but the weighting is about right and it feels nicely in tune with the rest of the carís responses.

Despite being massively more powerful, the HSV feels equally all-of-a-piece. Itís too big to really shrink around you on a tight, twisty road, but the carís inherent balance makes it a very friendly beast.

Selecting ĎPerformanceí on the Driver Preference Dial adds extra weight to the steering Ė though a little more response off-centre would be welcome Ė and firms the magnetorheological dampers, but the greatest strengths of the GTS are its brakes and ESP calibration.

For outright power, pedal feel and stamina, the HSVís monster AP Racing stoppers are absolutely world-class. Likewise, the way the ESP system will let the car move around Ė itíll allow a half-turn of opposite lock in certain situations Ė while subtly reining in any exuberance is on par with any other manufacturer. It allows you to drive hard with huge confidence without feeling like the car is doing everything for you.

The C63ís ESP isnít quite as lenient, but then its potency is such that a tighter hold on the reins probably isnít a bad idea. Traditionally, AMGís sedans have been comfy grand tourers, but the first C63 took a big step in a sportier direction and the latest model

The GTS allows you to drive with huge confi dence Ė its inherent balance making it a very friendly beast

has taken another stride again.

Handling response is now prioritised over ride comfort and with the chassis in its Sport mode the car feels taut and reactive. It skitters over small amplitude bumps and with less weight and stiffer suspension than the other two, body roll feels to be minimal.

Reverting to Comfort increases compliance and gives the chassis a little more Ďfeelí, but thankfully the ability to mix íní match settings means the softer suspension can be teamed with the most aggressive engine map.

The steering is weighty and requires a decent nudge to move off centre, but itís only when you switch back from the relatively mute Lexus that you realise the C63 has been feeding back a steady stream of information from the front axle. Once the Michelins have some heat in them, grip levels are high, but it quickly becomes clear that the best way to extract speed from the C63 is to maximise the effectiveness of the force of nature under the bonnet.

This means leaning hard on the awesome carbonceramic front brakes (a hefty $9900 option), rotating the car quickly mid-corner and then exiting as straight as possible to make the most of the available traction.

Itís a different technique to the balls-out commitment allowed by the Lexus, but devastatingly effective.

With Sports ESP engaged the electronics will only step in if youíve really made a hash of things, and itís handy to have the safety net in place as while traction is strong once the tyres are up to temperature, with what feels like about 10,000Nm on tap it only takes a poorly timed bump, camber or patch of dirt to have the rear squirming. The transition to slip can be quite abrupt, too, a characteristic shared by virtually every car we drive on Michelin Pilot Super Sports.

Theyíre also relatively noisy on Australiaís coarse chip rural roads, which combined with the firm ride Ė even in Comfort the C63 refuses to completely relax Ė will give those expecting traditional Mercedes levels of pliancy and refinement a wake-up call. Some find it a step too far, personally I think itís just on the right side of acceptable.

Itís a trait shared by the Lexus, though the GS Fís passive suspension setup can be quite abrupt at urban speeds. On the highway itís still firm Ė your passengers are going to know you bought a sporty car Ė but not necessarily uncomfortably so. Itís roughly comparable to the Sport setting in the HSV, which just goes to show the value of adaptive dampers, as a twist of the Driver Preference Dial selects ĎTourí for the GTSís clever suspension.

For outright comfort the HSV is the best here, absorbing all manner of road imperfections. Tour mode softens the dampers so much that the rear will actually bottom out over speed bumps, but on country roads it allows the GTS to lope along serenely, the

With supercar levels of performance in a four-door body, the C63 is a muscle car for the new millenium

Edition One First in, best dressed

OUR test car was the extrovert C63 ĎEdition 1í, essentially a special trim pack available to early buyers of AMGís latest twin-turbo terror. Priced at an extra $7900 and available on both sedan and wagon, externally the Edition 1 package includes 19-inch cross-spoke alloys, high-gloss black rear lip spoiler, side decals, chrome-plated tail pipes and red accents on the radiator grille and wing mirrors. Inside itís a mostly black affair with plenty of red contrasts, including the carbon-look centre console as well as the stitching on the seats, dashboard, steering wheel, door panels and armrests. Now sold out, 300 customers took up the option, but we have to say we prefer the subtle menace of the standard car.

Inside story


AS A smaller car the C63 lacks the space of the others but feels more bespoke with its diamondquilted leather and lashings of chrome and carbon.


ESSENTIALLY an up-spec Commodore, with all the good and bad that brings.

Ergonomics are excellent with plenty of room in the front and rear but strange mish-mash of materials.


MASSIVE digital screens make the Lexus feel very high-tech. Interior is high quality and has all the equipment you could possibly need but mouselike infotainment controller an ergonomic disaster.

steering also lightening to require less effort. Where the Australian loses points is low-speed refinement.

Thereís some heavy-duty engineering underneath the GTS and you can hear it with clunks and groans from the clutch, gearbox and diff around town. Itís not something that would be tolerated by either of the premium manufacturers, though AMGís MCT wetclutch auto isnít above a few low-speed stumbles.

The greatest difference between these three can be found in the interiors. All three are up against it to varying degrees by being the range-topping variants and therefore sharing interior architecture with much cheaper models, but itís in the HSV that this is most evident. Seats aside, thereís little to differentiate a $95K GTS from a $54K SS-V Redline, but then thereís not a lot to complain about either. The driving position is excellent, thereís plenty of equipment and masses of space front and rear for big, burly Aussie blokes.

Those same blokes would struggle in the back of the C63. Legroom is reasonable but the seat cushion is very short and simple physics denies it the head and shoulder room of its full-size rivals. Fine for kids, a squeeze for larger adults. Up front thereís plenty of alcantara, red-stitched leather and shiny chrome, though the Ďblood carboní effect on the centre console of our ĎEdition 1í test car (see breakout) is an acquired taste. Only the odd hard plastic surface is a reminder the C63 shares its roots with a $60,000 C200.

The Lexus is the most convincing in terms of material quality and also carries the most equipment, but sadly youíre more likely to be cursing the GS Fís clunky, unintuitive infotainment controller than admiring its fit and finish. The mouse-like touch pad requires significant attention to complete the simplest of tasks, attention that would be better served on the

road ahead. Itís a shame, as it takes the gloss off what is a nice place to be.

Which kind of sums up the GS F; itís a really good car, without quite nailing that final few per cent. It has a great engine, awesome brakes, handles well and is loaded with kit. At around $150,000 it deserves to be successful, and not just as a left-field choice.

Unfortunately for Lexus, the GS F is a very good car in the company of two outstanding ones.

If value for money took precedence, the HSV GTS would be an easy winner Ė how could it not? Itís unbelievably fast, the roomiest and most comfortable car here and more than holds its own on a twisty road, all for 60 per cent the cost of the others. Itís a phenomenal achievement for a small Aussie company, and itís difficult to countenance that the GTS will cease to exist in a little over 12 monthsí time. It has a huge appetite for fuel and tyres and has a couple of rough edges compared to other $100K rivals, but itís undoubtedly the best performance car Australia has ever produced.

But in terms of outright performance, the Mercedes- AMG C63 is our winner. At $172,310 as-tested, itís huge money, but in return provides supercar levels of performance and dynamics in a practical four-door sedan. Itís a high-tech hot rod, a muscle car for the new millennium and, for the time being at least, the best V8 sedan you can buy. Itís that simple.

Thirsty work Nat-atmo most effi cient

NO PARTICULAR surprise, the HSV the thirstiest car on test at 17.36L/100km Ė though under hard use the LSA can drink double that. The new-age twin-turbo C63 fared better at 14.16L/100km, but the economy champ was the naturallyaspirated Lexus with 13.39L/100km. In the real world, atmo equals economical.
