A truly desirable muscle car.

It doesn’t matter if you love traditional style muscle cars or you hate ‘em - the new VZ Holden Monaro demands admiration. It looks tough, sounds bloody incredible, goes around corners, stops and, yep, she’ll get up an’ go.

Boy, does it go!

The Monaro’s newly-tweaked LS1 5.7 litre V8 offers great throttle response and mind-blowing torque across the normal rev range. It doesn’t matter what gear you’re in or if you’re driving half asleep, you only need squeeze the throttle and – bang – you’re off. You can see the front passenger’s head flung back on almost every throttle application...

The sheer accessibility of this performance makes the Monaro very flexible and rewarding to drive. The only time you can catch it off-torque is when cruising in top gear (6th) at anything less than about 80 km/h. The engine is happy and docile enough to maintain a steady 60 km/h cruise in top gear (at a mere 1000 rpm) but it doesn’t really respond when you squeeze the pedal. But drop it back a gear and you’re romping away.

And, speaking of romping away, the Monaro is a car that can slaughter other ‘performance’ cars at the lights. No need for a tyre-frying launch – just floor it off the line and you’ll reach 100 km/h (62MPH) in around 7 seconds dead. With the traction control switched off for a big launch, the best 0 – 100 km/h (62MPH) time we recorded was in the low 6s.

That’s seriously fast.

The VZ update sees the Monaro’s pushrod LS1 bumped up to 260kW (350HP) and a massive 500Nm (365ft-lbs) (at 5600 and 4000 rpm respectively). Note that these are the highest power and torque figures we’ve seen from the LS1 with the exception of HSV’s 285kW (390HP) and C4B 300kW (410HP) engines. The newly Monaro engine also offers a massive 93 percent of peak torque from 2300 to 5300 rpm – no wonder it’s always ready an’ raring to go!

Changes to the engine include a revised camshaft, free-flow induction system, new ECU calibration (to suit high-octane fuel), electronic throttle control and a split dual exhaust that reduces backpressure by around 25 percent. Ahhh, the exhaust... The Monaro burbles and pops through its dual 95mm tips and is sure to put a smile on the face of any petrol head. But in light driving conditions, there’s only a distant murmur from the system so it’s not a constant annoyance.

http://us1.webpublications.com.au/static/images/ar ticles/i23/2378_2lo.jpg (http://us1.webpublications.com.au/static/images/a rticles/i23/2378_2mg.jpg)

The VZ Monaro can be purchased with a 4 speed auto or a 6 speed manual (as tested). The updated T56 manual ‘box receives shorter ratios, which are partially responsible for the car’s improved driving flexibility and response. Unfortunately, the shifter has a relatively long throw – a short-shift would be a nice touch. The LSD rear-end maintains the previous model’s 3.46:1 ratio.

The 1692kg (3,730lbs) Monaro is a relatively large car but drive it on a narrow, twisting road and is shrinks around you – the suspension, steering and overall feel come together very well. Our only criticism is the sports-spec suspension can be a tad harsh at times – there’s an occasional crash-bang into the cabin.

http://us1.webpublications.com.au/static/images/ar ticles/i23/2378_5lo.jpg (http://us1.webpublications.com.au/static/images/a rticles/i23/2378_5mg.jpg)

The Monaro exhibits a mild amount of turn-in understeer but the chassis is wonderfully throttle-responsive through the mid and late section of a corner. It also feels slightly more tail-happy than a Commodore sedan, but it’s never unnerving. The traction control system – which no longer kicks back through the accelerator pedal – is smooth and effective.

Under its skin, the Monaro is largely unchanged - the biggest change is the relocation of the fuel tank to between the rear seat and axle. Relocating the 70 litre (18.5 gallon) tank provides space for the fitment of a dual split exhaust and rear undertray which is said to reduce rear aero lift by 16 percent. The downside is significantly reduced boot space which is exacerbated by the relatively intrusive hinge mechanism – it’s a shame gas struts haven’t been installed to help maximise existing space.

http://us1.webpublications.com.au/static/images/ar ticles/i23/2378_10lo.jpg (http://us1.webpublications.com.au/static/images/a rticles/i23/2378_10mg.jpg)

The brakes instil the sort of confidence you want given the Monaro’s straight-line speed and point-to-point pace. The VZ Monaro has the biggest brake set-up of any Holden - 320 x 32mm ventilated fronts and 286 x 188 ventilated rear discs. The new Corvette C6 twin-pot calipers are also a stand-out from behind the front wheels. These come in addition to the other brake system changes found in the VZ update – there’s a new brake booster and master cylinder, standard EBD, ABS and brake assist.

Our only criticism is the slight oversensitivity of our test car’s ABS system – in one instance the pedal could be felt pulsing while braking with a front wheel over a manhole cover. Mind you, this was entering a corner at a fair click...

The downside of all these antics is a fuel bill that is nothing short of scary. Drive it so you can hear the exhaust and you will pay for it – we recorded over 18 litres per 100km during our test! Holden claim 15.3 litres (4 gallons) per 100km (62 miles) (ADR 81/01) for the Monaro 6 speed. And don’t forget the new engine tune is optimised to suit the expensive Premium Unleaded brew.

http://us1.webpublications.com.au/static/images/ar ticles/i23/2378_4lo.jpg (http://us1.webpublications.com.au/static/images/a rticles/i23/2378_4mg.jpg)

Despite the rorty nature of the car, the Monaro is remarkably pleasant, comfortable and easy to drive. The cabin offers roomy seating for four and all seating positions are comfortable enough to be used over long distances. The deep, heavily contoured front seats attract praise from everyone but – equally - access to the front and rear seats drew criticism. The first time you step into the Monaro there’s a high probability you’ll crack your head on its sloping A-pillar. Access to the rear seats is also made difficult by the bulky front seats and their slow single-action tilt/slide mechanism.

And what about interior gizmos? Well, you get dual-zone climate control, front and side airbags, a comprehensive trip computer, electric seats (with memory settings on the driver’s side), a punchy 6-stack CD system and cruise control. A handy parking distance beeper is also included in the deal.

The instrumentation markings are attractive in an old-school sort of way and there’s an add-on binnacle on the centre of the dash containing an oil pressure gauge and volt meter. Unfortunately, these are not angled toward the driver – they’re aimed straight down the centreline of the car. The cabin is fully leather-lined and comes with highlight stitching on the steering wheel, gear knob and park brake lever. There are also glossy ‘piano black’ trims, which show dust and finger prints.

The VZ Monaro attracts more attention than almost any other stock-standard car we’ve driven. The Monaro shape is well proportioned, smooth and attractive and the VZ update adds a bit of extra sex appeal. The bulging bonnet features Pontiac-style scoops (which don’t feed air to anything), there’s a revised grille and headlights plus a deep front facia with a vertical slots containing the park and projector-type fog lights. The rear is distinguished by aftermarket-looking 95mm chrome exhaust tips and a black mesh lower skirt. Rims are attractive 5 spoke 18 x 8s wearing 235/40 Bridgestone Potenzas.

In one admirer’s word, “it’s pure horn.”

With a retail price of AUD$60,490 ($46,152.34 USD) the VZ Monaro is one of the most expensive Holdens you can buy. But compare it against cars like the Nissan 350Z, Chrysler Crossfire and the big-power Euros costing more than twice as much and it starts to show its value. Ask yourself this; with the exception of the Holden-based HSV GTO, what other big performance coupe can you buy for anywhere near the price of a Monaro?

There’s nothing.

The Monaro is a car we’ve absolutely loved during our test. It scores very well in all areas with the exception of its oh-so-slightly too firm ride, reduced boot capacity and its dunce-hat rate of fuel consumption.

But nobody can deny its character and capabilities.

Good review. It seems the rest of the world gets what the Monaro/GTO is, except the US rags.

It's all in the name I'm afraid. The ghosts of the past haunt the car in the US.

Well the wierd thing is the valve covers say 5.7L but the throttle body is Drive by wire with the 85MM MAF. I was pretty sure the VZ got the LS2?

GTPprix
12-18-2004, 08:27 PM
Never mind, I see how they did the integration of the LS2, they just used all the electronics on the old LS1 to keep it simple for wiring/calibrations. DOH! ;) I don't know why I thought all Monaros got the LS2 now.. hrmm hehe

correct it is electronic throttle, but still ls1.

current HSV's have the ls2 though, and they are making a big impact locally (without headers from the factory i might ad)

dude the thought of moving to the US crossed my mind, the size of your market and/or tax situation.. if I could get an E55 for $75k US.. jeez..

or a monaro of $20kUS for that matter

here the E55 is over $200k aussie and the monaro about TWICE the adjusted cost versus what you guys are paying. Granted the basic equipment is lower in the US but i really dont care about that, that is worth maybe $1k to me.

Oh I know I chew out people regularly when they whine about the sticker price of the GTO "Do you have ANY idea what this car costs in the place its manufactured?"

I just look at it as the fact you guys can easily (not cheaply) buy any HSV car ;)

all i can say is thank god the local GM dudes stuck with RWD V8's otherwise i would be driving some ricemobile and creaming my pants over clear tail lights.

the local ford people DROPPED the v8 in the 80's, they are only now recovering locally

I'd rather have the Barra 240T than any LS1 or LS2. :p

i find the 6T falcons relatively boring. very smooth, deceptively quick, cheap to mod, but boring... give me the v8 anyday, falcon or commodore. The only real problem with the falcon otherwise is the weight at about 200 kegs heavier than equivalent commodore. I've driven the 6T a bit, it's definitely a safer and more well behaved drive. had my eye on a FPV Typhoon, but initial tests have shown the initial hype a little premature.

Great post - Thanks.


Now, what is the part number for this...?

I don't know. But you can contact a Holden dealer and order the pod and the gauges to match your gauge cluster, hooking them to the engine shouldn't be a big deal.

Only the HSV GTO's have the LS2. Here is the latest info on the 2005 LS1 in the monaro.
