MG ZR ZS ZT Technical - MG ZT & ZT-T 160 with turbo K4

Release immediate
October 3, 2002


MG’S SPORTING TAX-BEATER

MG is today (October 3) launching a new 160Ps high-efficiency turbocharged K Series engine to power the MG ZT saloon and ZT-T estate 160 derivatives. The turbocharged and intercooled 1.8-litre K Series engine answers the UK’s demand for a CO2 tax-beating car with a sports appearance and excellent chassis characteristics.

The 1.8T engine replaces the former 160Ps 2.5-litre V6 engine of the ZT 160 and ZT-T 160 models, yet despite offering the same power, provides even greater all-round performance with significantly reduced fuel consumption and a crucially better CO2 rating.

The new 1.8-litre turbocharged versions of the ZT range expands the appeal in both company car and retail sectors, with a CO2 rating of 194 g/km and a Euro III standard combined fuel economy figure of 34.9mpg. These figures compare with 225 g/km and 30.0mpg for the previous 160Ps V6 model. The high efficiency turbo unit delivers worthwhile gains in performance, reducing the 0-60mph time from 8.8secs to 8.5secs, and the fifth gear 50-70mph time from 10.7secs to 9.8secs (similar improvements also apply to the comparable ZT-T estate car versions).

Because the turbo unit has been specifically developed for high torque in the key driving range, with 215Nm available all the way from a mere 2100rpm to over 4500rpm, it has a strong and tireless character, to be enjoyed either on the longest journey or the shortest sprint.

The gearing of the new ZT turbo models has been carefully optimised to combine performance and economy. A final drive ratio of 4.167:1 provides overall gearing of 22.2 mph/1000 rpm in fifth gear, which places it between the gearing of the former ZT160 (23.4mph/1000rpm) and that of the continuing ZT190 (21.0mph/1000rpm).

Many drivers will also enjoy the enhanced responsiveness and agility that the 50 kg lighter power unit adds to the already sporting ZT chassis.

New Generation Turbocharger

The new turbocharged MG ZT models use the latest Garrett GT20 turbocharger with T100 turbine wheel design. This new-generation unit moves away from traditional turbocharger configurations, which until now have been predominantly designed for diesel applications. The T100 is a dedicated petrol engine concept, shaped to work more effectively over the greater speed range of modern petrol engines such as the K Series. In order to retain good off-boost efficiency, a balanced combination of moderate boost pressures and a relatively high compression ratio is used.

The unit incorporates a special cast stainless steel exhaust manifold able to withstand temperatures of around 1000°C, with specially developed pistons and connecting rods, and an uprated oil pump.

Available in showrooms from early October, the new 1.8T models will carry on-the-road pricing from £18,970 for the ZT 160 saloon and £19,580 for the ZT+ 160. The ZT-T 160 estate starts at £19,935 and rises to £20,545 for the ZT-T+ 160.

Not sure that all those MG guys whoever they are appreciate their phone numbers being posted on the net!

Good news on the 160 though!
Jeff Glover

Exactly!

Oops! Never mind ... but even if the 160PS 1.8 Turbo may be a good move for tax reasons, the loss of the 160PS KV6 derivative is a shame.

When might the new turbo & diesel engines appear in
the ZS models?
I have been waiting for almost a year to have a decent
diesel or a higher performance "four" installed in the ZS.
andrew

'New turbo diesel'??

Turbo diesel ZS announced in July and available now. Uprated L series diesel kits are a little way off, but should arrive eventually. In the meantime such upgrades can be siourced from JE Engineering, Baggington, Coventry and the power rises around 25 bhp along with around 10 to 15% more torque.

Roger Parker


Roger
Are you talking about the NEW turbo diesel which was announced then,but I thought only for the ZT ?
Thats what I would like in the ZS,not the old noisy,vibrating 101 HP engine previously used-with torque upgrade or not.!
andrew

No the L series as found in ZR. Announced in July means that even with quick model updates this certainly isn't going to be changed in just a few weeks. The BMW M47 2 litre diesel in 75/ZT remains only in that car and the ZR and now ZS use the L series diesel. However now that the manufacturing has been moved from Land Rover to Longbridge, (BMW moved it from Longbridge to Land Rover just before they abandoned ship) and once certain fine details are negotiated between MG Rover and Ford concerning this engine then there is a great deal that can be done to bring this engine up from a second generation to a leading edge engine on a par with the VW 1.9 TD, which is also an 8 valve unit. This will take some time though. In the meantime don't expect any other makers engine to appear in the frame.

Rog
Roger Parker

Sorry Roger but am still not clear.
Is the turbo diesel NOW available in the ZS essentially the same as the 100 HP diesel previously available in the Rover 45,or has there been some significant improvement to it this summer?
andrew

Yes is the short answer.

It is the same L series engine in the same direct injection 101PS format with 240Nm of torque. It is available now and appears in all current price lists in two forms with either 4 door or 5 door body styles. Prices range from 13060 pound for the 5 door base to 14890 for the 4 door plus model - before discounts.

Rog
Roger Parker

Thanks Roger-but this is precisely the Diesel which
is now rated uncompetitive in terms of noise +vibration
if not on power.Is the new uprated 135 HP Diesel much better in these respects ? Any chance of it ever being installed in the ZS as well as the ZT ?
andrew

Andrew if you want more performance out of the 4cyl ZS there are ways and means of extracting extra BHP without breaking the Bank.150BHP is easily obtained.
Unless you want a diesel(?)
Mike.
mike

Who is going to be the 1st to make a new mg metro turbo?
Leon Ruddick foster

Thanks for your advice Mike-who could supply such a vehicle in the UK?
although I am not too keen on tuning up cars because of its impact on guarantee,insurance etc
Plus,in France where I live for the moment,it is actually illegal & not possible to register a tuned car so would need to have it UK registered
