On
January 1st, legendary British luxurious brand Rolls-Royce shifted
ownership
from Volkswagen group to BMW. The new generation, BMW-developed,
Goodwood-built
Rolls-Royce Phantom was also launched at the same time. Rolls-Royce
entered
a new era.
In response to those who doubt the identity of the reborn Rolls-Royce - is it really British? or actually a BMW 9-series with a RR badge? - BMW took special care during the 4 and a half year preparation. Firstly, they set up a studio in London and employed British Ian Cameron as design chief of the project. Then they built a factory in Goodwood of England - the place famous for classic car festival - and employed skillful British craftsmen for their wood and leather workshops. From the pictures, I am amazed by how retro the Phantom looks. It seems the team led Cameron deliberately injected a lot of, or even too much Rolls-Royce-ness into the new car. For example, the square RR-corporate grille is considerably larger than that of the outgoing Silver Seraph, so large that it feels quite imposing to eyes. The body profile also delivers a sense of heavyweight and security (or bulky, if you don’t like it) like some older RR, more so than the Silver Seraph. Ridiculously, Silver Seraph looked advancer than the new car.
What made Rolls-Royce lighter than its arch-rival Maybach is the use of aluminum space frame chassis instead of steel monocoque. The chassis is constructed from aluminum extrusions, castings and pressed aluminum sheets mainly, with steel front subframe and aluminum rear subframe for mounting suspensions. Most exterior panels are aluminum, except the composite front wings and steel boot lid. The whole body-in-white weighs 550kg, compare with Maybach’s 622kg. This seems not very remarkable for an aluminum space frame chassis, but you should notice that the chassis of Phantom achieves a super-high torsional rigidity of 40,500Nm/degree. A few months ago, Volkswagen claimed its Phaeton was the stiffest in the world, at 37,000Nm/degree. For comparison, an Opel Vectra is 18,000Nm/degree only.
Predictably, many critical mechanical components are sourced from BMW. The V12 engine is derived from 760Li’s, with capacity enlarged to the magic number of 6.75 litres. It still has the long list of technology, such as Double-Vanos VVT, variable exhaust, Valvetronic and direct-injection which allows 11.0:1 compression ratio. These enable a maximum output of 460 horsepower at 5350rpm, slightly more than that of 760Li. However, the focus is on torque - with both stroke and intake manifold longer than the BMW version V12, the Rolls-Royce engine generates 531lbft at 3500rpm, compare with BMW’s 443lbft at 3950rpm. Moreover, from just 1000rpm there is 75% or 413lbft available. Rolls-Royce’s customers used to criticize the old 5.4-litre V12 of Silver Seraph not as torquey as the traditional V8, now they should satisfy with the new V12. Phantom's boxy shape is very aerodynamic inefficient, as you can see in its 0.38 drag coefficient. Also, its large frontal area should produce a lot of air resistance. Anyway, its top speed is regulated at 240kph (not 250kph this time) or 149mph. Rolls-Royce claims acceleration from rest to 60mph takes 5.7 seconds, slower than 760Li and Maybach but I think no one will complain about that.
One of the special features is rear-hinged rear doors. Unlike Mazda RX-8, the rear doors of Phantom can be opened and closed independent of the front doors. The benefit? Rolls-Royce says they let the passengers "exit far more gracefully". The cabin locates quite backward, because Phantom employs double bulkheads behind the engine for better sound insulation. The floor is also double layer, raising the cabin floor level to enable a nearly flat floor. In other words, the transmission tunnel intrudes just 3 inches into the cabin. The rearward cabin also positions the rear seats deep into the C-pillars, enhancing privacy of the passengers, said Rolls-Royce. On the Road
Now drive it. Press the starter button, the 6.75-litre V12 idles silently. Move off the line gently, the Phantom hardly transmit any noise to the cabin, thanks to the vast noise insulation, double bulkhead and double layer floor. The V12 spins so smooth and the ZF gearbox shifts so seamlessly that you nearly think this is an electric motor. In the Phantom, speed is not related to noise and harshness until 100mph. Only after then the wind-blocking shape generates a lot of wind noise. The Phantom rides smoothly, especially at low-speed and bumpy surfaces where competitors usually suffer. Its chassis is well sorted out. At first you might feel the tuning too soft - the steering is very light, the car rolls too much and too early in corners. But for this kind of cars such compromises is necessary in order to obtain first-class ride quality and ease of driving. In fact, the Phantom conceals its size quite well. Its steering is communicative, giving you confidence to place the car accurately. At 50:50, the car is well balanced. At the limit, neutral gives way to gent understeer, so it is easy to handle. Of course, don’t compare it with Mercedes S-class, because the Rolls-Royce is much taller, heavier, bigger and ride softer. After decades of
falling,
we are glad to announce that Rolls-Royce is reborn. Phantom not only
helped
RR regain its position as the best luxurious car brand in the world but
it also passed the test for Rolls-Royce-ness. We just hope it could
look
more beautiful. |
