Product: Plymouth SuperBird Road Runner (25721)
Manufacturer: Carrera

I've driven down many a high street and only just managed to scrape past an on coming Volvo - well imagine trying to get past someone who's more concerned with how they look and is driving a small truck. This is what I imagine trying to get past a Chrysler Plymouth SuperBird is like. Well in the good old US of A during the 70's and 80's the bigger the better (especially in less environmental friendly states than California), thus the site of a hulking performance car growling down your street was not uncommon.

Pedigree of an American Icon
The race going Chrysler Plymouth SuperBird had an enviable pedigree being raced in the 1970 NASCAR series against its Chrysler sister the Dodge Daytona and Fords Torino Talladega and their Mercury Cyclone Spoiler II. The 1969 and 1970 NASCAR series have been affectionately termed the Aero Wars because these two seasons saw the manufacturers concentrate on aerodynamics rather than just the brute horsepower of before. This led to the characteristic wedge shaped with a huge aero-wing.

Well it is commonly remembered that in 1970 Chrysler and the SuperBird kicked-butt. During this season the Plymouth SuperBird won more races in fewer appearances than its winged brother the Daytona, bringing home eight of Chryslers 21 victories. The Plymouth was considered a great success, although ironically, Bobby Isaac won the 1970 Grand National Championship driving a Dodge. In 1971 NASCAR, because of the total dominance of the aero cars, reduced the engine size limit which basically banned all the aero cars from completing from then on.

It is thought about 2000 SuperBird road version were produced and it is estimated about half of them still surviving today. These cars have quick -huge engines, a wedge shape and a massive aerofoil on the back to provide some form of cornering stability. Like the cartoon its reputation was one of nothing (not even a wile coyote) could catch a RoadRunner and to own one was to be every boy racers dream. However both the Dodge Charger Daytona and the Plymouth SuperBird were out of production less than eighteen months after the first one rolled off the assembly line. Why? Well emission requirements were becoming much tighter (not good for a high performance motor) and insurance premiums were rocketing. Boy racers who often struggled to find the cost of the car were finding the premiums unaffordable.

However these aero cars and especially the SuperBird are American icons

How Does It Look?



First thing you notice is how big it is. Carrera produce a larger than average perspex box and this car fills it. On removal I immediately noticed the new chassis that is now used with all Carrera models. It comes with two magnets, including the ingenious sliding magnet, and a second one placed just before the rear axle. Anyway more on that later.

Comparing it to pictures of the SuperBird I can say Carrera have really captured the lines and look of the real thing. The colour that is impregnated in to the plastic, which I don't think pictures do justice to, is a turquoise aqua marine (i.e. blue!) and is actually quite stunning. The roof mimics a convertible soft-top although this one does not actually come off. There are a few tampo printings including two bonnet latches and the distinctive RoadRunner logo on the bonnet (hood), and on both sides of the wings.



Plymouth is emblazoned on the sides at the rear and in corporate style just above the rear bumper (fender) area. The 'BA ZONG' plates front and back are clearly visible. All the printing is ultra crisp and all the words can be made out with the naked eye. Overall although it looks sparse, compared to a race liveried car, I found myself really liking it - it is a real grower and the sparseness makes the excellent RoadRunner logo stand out.

Looking inside the cabin you see the cool dude with black raybans, a closely cropped hairstyle and dark suit. The rest of the interior is minimal although you can make out reflection in both the wing mirrors and rear view mirror. It is just like a road version should be and you can just imagine the Beach Boys blaring out as this guy drives down a Californian highway.



What Makes It Go?
I found the wheels and tires, with Goodyear clearly printed on the sidewall, nice and true although the tyre compound was quite hard. I trued all tyres a little and this did help performance but I did not gain a huge improvement - basically this car drove exceptionally well straight out of the box.

The chassis is the new breed from Carrera. In addition to the standard sliding magnet they have included a powerful magnet just in front of the rear axle. I found than on placing the car on the track (flat Sport track), the rear magnet was so close to the track it really struggled to get round and where there was a slight track bump it grounded unwilling to move. I don't like magnets and I felt this was way over the top, so I removed the rear magnet and found there was a shim in the bracket that made the magnet sit that much closer (i.e. too close) to the track. I removed the shim and reinstalled the magnet. Now the car went very smoothly round the track, although it was still rather too stuck down for my liking.



Also of note is that now the chassis has snugly fitted brass bushings both on the front and rear axle. On both axles there was only minimal movement in them, which is excellent. The only issue you will have especially if you run on less than even surfaces (e.g. Scalextric Classic, SCX or Ninco track) is the lack of vertical movement in the front axle could result in some deslots over bumps as the front wheels ride over them pushing the guide out of the slot. However, if you run on a flat track then this lack of vertical movement is, in my opinion, optimal. The gearing is really smooth and Carrera have (as always) gone that extra touch and thoroughly greased it which is ideal for a newbie as the car won't need any maintenance for quite a while.

Previously the gear ratio Carrera used was 2.6:1 which gave a good top end speed but it took a while to get there and braking was poor - good for long flowing tracks but not good for most homeowners short and twisty tracks. Now they have changed the ratio to 3:1, which gives the car better acceleration and braking. On the GS test track I did not notice a lack of top speed compared to previous Carrera cars as I never got them up to top speed. Overall the chassis is an excellent development and has made Carrera cars much more competitive.

One thing to note, if you are not familiar with the Carrera chassis, is that it has a reversible switch that allows you to change the direction the car travels - I've had it knocked over in racing on my bumpy Classic track with humourous results. The motor is a good powerhouse chucking out 26k rpm and the guide while a little bit sloppy sits in the slot of the track all the way.

On the track
Putting the monster on the track after removing the rear magnet shim I managed 50 very quick laps - straight out of the box I managed 5.46seconds on the standard GS test circuit, which is superb.

I then trued the tyres a little, cleaned them and added a touch more lubrication to the axles. After another 100 laps I managed a best time of 5.35 seconds and was consistently lapping at about 5.40 seconds. I had a number of big offs and although the rear wing came off it did not break and was easily just clipped back on.

I took the rear magnet out and put the variable sliding magnet in its rear most position and what I got was a much more satisfying drive. The car power slid through corners nicely and with the over all speed much reduced I only came off a couple of times in the 100+ laps. When I did come off I did so much more gently with no damage. The best time I posted was 5.82 seconds and was consistently at the 6-second mark.

I did not test it without a magnet but my feeling was it would take a lot of work to get it to run quickly as it was very high and the tyres were narrow and quite hard.

Sum-up
When these were released they never took my fancy, as they had never been a part of my motor sport experience. However the look of this monster has really grown on me and its track performance, whilst not scintillating is, for the size and weight of the car, extremely good. I actually plan to try and tune this car up for non-magnet racing and enter it in to my clubs NASCAR series.

There are a number of models available if you want a line-up of these however I quite like cruising this round my circuit with the Beach Boys blaring in the background imaging all the bikini clad girls watching me! Well imagination is a great thing.
