While the former V12 weighed 240 kg in its first version (5 liters), the new beast weights 280 kg. It doesn't produce less than 445 hp (ECE) at 6000 rpm (10.9 bars of mean effective pressure) and 600 Nm at 4000 rpm (12.5 bars of m.e.p.). Its torque back up calculated this way is thus 12.5/10.9, that is to say 1.15 or 15%.
However, by letting it rev up to the 6500 rpm redline one will obtain if necessary (!) a torque back up of 33%... Such a power curve is enough to catapult the 2.09 tons of the 760i to 200 km/h in 17 seconds, 100 km/h being reached after 5.5 seconds. In conjunction with an axle ratio of 3.15 and tires of 245/50R18, the ZF 6HP26 automatic transmission without direct drive gives 64 km/h per 1000 rpm in 6th speed. Its ratios are 4.17 – 2.34 – 1.52 – 1.14 – 0.87 – 0.69. Standardized fuel consumption is indicated at 19.5 l/100km in city driving, 9.2 highway and 13.4 average. The longer version 760iL being 160 kg heavier, it burns 1 l/100km more gas in city driving. With its high compression ratio of 11.3 :1 the over-mighty V12 prefers the 98 ROZ high octane gasoline, but it can, if required, also live with 91 ROZ gas.
The announced performances are even higher than those of the former Alpina B12 6.0 of 430 hp, except that the maximum speed is limited at 250 km/h whereas the B12 could reach 291 km/h. Bah, rounded off 290 km/h (180 mph) would have been enough I guess… and undoubtedly 250 km/h also is.
But just in case you need more power and speed, the tuner Hamann has presented at the 2003 Geneva Motor Show an upgraded version. Extract from their press release:
