The new engines are all more powerful than those they replace, but fuel economy is improved in most and unchanged in the V8 petrol engines, thanks to refinements of BMW's Valvetronic petrol engine technology and third-generation precise piezo-injection in the diesels (which meet the Euro IV emissions standards, even without the now-standard particulate filter). Of course, all this is relative, with the 730i managing 27.9mpg, the 730d 34.5mpg and the 760i just 21.1mpg, but not bad for cars this size and weight; carbon dioxide emissions range correspondingly from 216 g/km (730d) to 330 g/km (760Li), so company car tax will be hefty. The biggest cost will be depreciation, especially for models with the larger petrol engines, but secondhand demand is usually strong - especially for diesel versions - so falls in value should be marginally less savage than for many other cars this size. The SE or Sport packs will be crucial to maintain resale value, however, along with options such as the rear-seat entertainment package.
