New PRV (PSA) 210HP!

Hello, while surfing the net I came across this press release on the new "PRV" engine.
Quite a few years have passed since the DeLorean's birth, and one of the change with the PRV (Peugeot-Renault-Volvo) consortium in Douvrin, France, was that Volvo pulled out. Volvo is now owned by Ford.

The PRV changed name to PSA, andconsists now of only the French automakers Peugeot-Citroen-Renault.

Some of you may remember I mentioned the new PRV-V6 on the list a few months back...one of the European cars that have it installed is the Renault Clio (rally version). I wonder if the new engine would fit in the DeLorean - I believe it would. If you would like to see a photo of it, go to the DMC News vault and find it in the folder New PRV. The engine now produces 210 horsepowers! More info on http://www.psa.fr/ The only thing difficult now is to think of it as a PSA instead of a PRV ;-)

Best wishes

PSA PEUGEOT CITROËN and Renaultto Introduce New V6 Engine

Beginning in early 2000, a new 3-liter (2,946 cc)V6 engine, developed by a cooperative venture between PSA PEUGEOT CITROËN and Renault, will be gradually introduced on both carmakers’ mid-range, upper-range, and MPV model lines. The first vehicles to be equipped will be the future Peugeot upper-range model scheduled for presentation atthe Frankfurt Auto Show in September, and the Renault coupe developed from the Avantime concept car. The new engine, which is an improved version ofthe ES9 model introduced in 1996, was developed at a relatively low cost of FRF 464 million, of which FRF 80 million in capital expenditure. It will improve performance and lower fuel consumption, while complying with new Euro3/2000 emissions standards. A Euro 4/2005 version will be available in the near future. The engine will be produced at a rate of 300 units aday at the La Française de Mécanique plant in Douvrin, France.

Specifications for the new PSA PEUGEOT CITROËN/Renault 3-liter V6 engine call for:
- Lower fuel consumption.
- Better performance (power and torque).
- Compliance with new European emissions standards to become effective in 2000 and 2005.
- Possibility of two-way dialogue with an automatic transmission to adjust torque to gear changes.
- Easier maintenance, with oil changes every 30,000 kms, low viscosity oil and sparkplug changes after 120,000 kms.
Performance, consumption and handling
The new engine’s power has been increased by 8% to 152 kw (210 hp), versus 140 kw (194hp) for the engine it is replacing. Maximum torque is 285 N.m at 3,750 rpm, versus 267 N.m for the earlier version. Low speed torque has been thoroughly reworked and increased by 10% to 260 N.m at 2,000 rpm, providing a more pleasurable driving experience.

Fuel consumption has also been substantially improved. While mileage will vary, depending on the marque or vehicle type, overall consumption has been lowered by one liter per 100 kms, in combined European city and highway tests (ECE and EUDC standards).

Superior environmental performance
Improving the engine’s technical features has also significantly enhanced its environmental performance. The new PSA PEUGEOT CITROËN/Renault V6 engine complies fully with Euro3 standards (to be applied as of January 2000 for new models) and will rapidly be upgraded to meet Euro4 standards (for which tax incentives will be offered in advance of the January 2005 application date).

Adjustments to the new standard will involve the engine management system, the precious metal content of the catalytic converter, and development of the European On-board Diagnosis (EOBD) system. These improvements will be integrated gradually, depending on the two partners’ new vehicle introduction schedules.

Major technical changes
The engine has been entirely redesigned, with a thoroughly reworked upper section. Changes include:
- A newly designed combustion chamber and intake manifold built in partnership with Porsche, for the combustion management system, and with Bosch, for the engine management control and injection systems.
- Engine acoustics (NVH) were handled in association with Ricardo.
- A new six-pipe intake manifold, increased to 12 pipes where it feeds into the combustion chamber, with each nozzle positioned on two pipes.
- Multi-hole and sequential injection nozzles.
- Motorized throttle housing.
- Single coil ignition system (one per cylinder).
- Variable timing camshaft.

In the lower engine section, the crankshaft, made of meshed forged steel and machined with variable burnishing, is produced in France at the Courcelles foundry.

Investment and production
Development of the new V6 engine involved one-time expenses (for design, engineering and process development) of FRF 464 million, of which FRF 80 million was investedin manufacturing facilities. The original engine, introduced in 1996, had cost FRF 2.5 billion, including FRF 1.3 billion in capital expenditure.

The engine will be produced at the Douvrin, France plant operated by La Française de Mécanique, a joint PSA PEUGEOT CITROËN/Renault venture. Full-year output is forecast at 300 units a day, versus the 120 units a day currently produced. This 250% increase in volume is in line with expansion in both Groups’ model line-upsand the large number of vehicles to be equipped with the new V6 engine.
