It was only six years ago that the world’s interest was well and piqued by a compact, snappy two sporty concept car named sitting on the Toyota stand at the Tokyo Motor Show. A response was all that Toyota and that car became the mid-engined MR2 Runabout 2 seater) which has enjoyed outstanding world-wide According to Toyota, over a year period 163,000 were produced. Of these 97,000 were shipped to the US, were exported to toher countries and 41,000 were on the domestic market. To date, no mid-engined two seater has been so on the worl market, especially you consider that other cars fail to generate than a couple of hundred a month.

NOW, AFTER minor facelifts during its generation, Mister Two as it has come to be has been re-born as a larger, mid-engined sports car, serious in concept and execution its predecessor. In its original sales Toyota promoted the MR2 as a personal vehicle rather than a sports car. The slant was on as in the US 60 per cent (UK 40 per cent) of its buyers out to be women. With the tastes of target group in mind impressions of the new MR2 are startling given its wider and lower form.

No matter how you look at its sleek from slanting nose and side air intakes to its smooth and rear end, the car screams In fact during the car’s press launch the most comment amongst the assembled scribes was the MR2’s resemblance to a filling the rear view as it comes screaming up behind In fact, with the 2.0-litre, twin overhead cam, 16 four cylinder powerplant right behind your the deep engine note and mechanical noise definitely up images of a prancing horse.

In there are three MR2 models, the G and G powered by an upgraded version of the 2.0-litre four in naturally-aspirated and the twin-ceramic turbo GT. The non-turbo 123 kW at 6800 rpm while the turbo out a meaty 168 kW at 6000 rpm. The GT is with the same twinentry turbo as the Celica GT-4 was virtually free of turbo lag our test drive.

Steering the more luxurious MR2 was a definite Selecting first and giving the a shove propels the car forward a stronger punch than Although the new MR2 in nonturbo form is than the original model its 3 5 kW of power more than lowering the power-toweight ratio to 9.8 from 11.9 kg/kW. The GT, with an even lower ratio of 7.4 kg/kW, rockets rest to 100km/h in a claimed 5.8 a figure on a par with the Porsche 944 and blasts over the standing 400 of 13.9 seconds. The deep of the engine changes to a satisfying once the rev counter climbs 4000 rpm. Slotting the gear into each of the gears is a pleasure when with the smooth and progressive

The new MR2 is fitted with rack and Electro-Hydraulic Power Steering a new system that extracts not from the engine but from a electric motor and hydraulic Its sensors monitor vehicle and steering angle, adding where necessary.

A fault of system which surfaced our test session was a loss of assistance when braking from high speed.

The dominant handling trait is but this changes to oversteer in no manner if the boot is kept in.

The suspension set up remains the same as the model with struts, springs and anti-roll bar front and however the shock absorbers been upgraded. Braking is now by disc front and rear, and work extremely well. The cockpit of the original model has replaced by a more subdued passenger car type dash. is the racing style tacho, by a standard rev counter.

The steering wheel, park and gear shift are all leather The seats are comfortable and supportive and vision is excellent. Accommodation is very much for two and luggage in the boot is modest. A T-bar available on the home and some markets is unlikely to see the light of day in given the size of the market and the of hassle involved in Australian Regulation (ADR) compliance. A launch date for the MR2 in Australia is the same time as the US. And it’s that Oz will start off the nonturbo car to be followed by the turbo

4500GT THE CRITICS may have it ugly but no one should underestimate the of Toyota’s 4500GT experimental It is yet another serious bid by the Japanese to breach Europe’s upper defences. The target this is Porsche’s 928S4.

Its bullet with considerable mellowing by time, could conceivably the Weissach defences, too, for hi-tech Toyota prototype is to cruise at an astonishing 300 km/h four adults and their comfortably stowed.

The world’s press got their first to actually drive the Toyota made its debut at the recent Motor Show to almost thumbs-down response over its styling—at the Toyota test at Susono, Japan.

Their response, after putting it through its dynamic as much as they could, a rev-limiter that held top to no more than 200 km/h— was far positive. Speculation’s now about the 4500GT will appear, by 1992, wearing Toyota or badges. more likely the for at its heart is a new five-valves-percylinder 220 kW evolution of the sedan’s quad-cam 4.5 litre V8.

The up front, drive’s by rear with a new six-speed manual mounted in combination with the axle to give a perfect weight distribution. The engine and are linked by a lightweight high carbon composite torque that enhances smooth acceleration.

The experimental version’s eagle-like nose and sliced-off form —vaguely reminiscent of Italian sports car-types—is far too radical for mass acceptance. some o f its styling cues remain, Toyota insiders say the mock-ups of the actual production around 1992— is far more

The 4500GT boasts a low front co-efficient of just Cd 0.29 and to its aerodynamics and reduce any tendency to at high speed, is fitted unique air outlets on the hood expels the air over the vehicle. Its shape— rounded entry and exit—is one of the most stable of forms and was selected after tested 20 different shapes in the

The body’s front bumper engine compartment and under have also been to provide sufficient cooling for the engine and brakes. A rear body cover has also fitted to minimise wind

The new quad-cam 40-valve engine is in alloy, with magenesium covers, oil pan etc. and, to sure it sounds good, a two-way exhaust system, reduces exhaust gas back is designed to impart a low or throaty depending on operating conditions.

The generates its 221 kW power at a lazy rpm and develops an up-theside-off-a-building 383 Nm of torque.

the prototype has a claimed top speed of 300 covers a standing 400m in 14s—on the test day a rev-limited cut in at rpm. Even so, the Toyota to 100 km/h in under seven and cruised on the highspeed bowl at 200 with absolute ease. in the near future Toyota permit a road test to fully utilise those 40 at perhaps 8000rpm. the engine feels that strong.

The six manual remote-controlled gearbox is notchy. At 5000rpm in 6th, the read 200km/h which that 300km/h could be at 7000rpm. It goes without but at 200km/h the car is faultlessly stable. at 200 km/h engine and wind are quite noticeable in the cabin, a Ferrari-like throaty growl up front letting you know are happening. The 4500GT’s clutch—unlike heavy duty sports surprisingly light.

Its suspension has also been with a four wheel wishbone geometry. The front is with A-type upper and L-type lower arms the rears are fitted with upper arms and A-type arms, giving improved at high speeds.

The driver’s is firm but comfortable, providing vision for a car of this nature. As other 2 plus 2s, the rear offer leg room sparingly.

Not the 2000GT which debuted 22 years ago, has Toyota the GT label to name one of its sports Supporting the belief that car will become a production is the fact that its revamped just happens to be the same one set to the new generation Supra, with a release date of 1991.
