The 850R also benefits from extra 10 lb ft of torque; peak torque is 258 lb ft
(350 Nm), produced between 2400 rpm and 5000 rpm.
An advanced electronic engine management system and a new exhaust manifold,
ensure that although the 850R has a bigger turbocharger, it isn't plagued by the `turbo
lag' normally associated with large turbo units.
Top speed is electronically limited to 155 mph, and the 850R accelerates from
0-62mph in just 6.7 seconds.
This level of performance imposes heavy demands on both transmission and chassis,
so the 850R's improvements include all components subject to increased stresses.
TRACS (traction control system) and the addition of a viscous coupling on the manual
850R minimise wheelspin and improve roadholding while cornering.
The chassis settings have been re-tuned to improve comfort. The anti-roll bars are
more slender than on the T-5R to permit more lateral roll, which in turn allows for
stiffer damper settings.
High standard equipment levels on the 850R include
ABS,
side impact airbags,
electronic climate control, a trip computer, electric windows all round, a sophisticated
6-speaker CD stereo system and new sports seats.
The 850R is available in both saloon and estate versions, priced at £33,550.
