We say Dull compact exec estate that relies heavily GM parts bin bits and pieces. That means that it’s fairly solid but harldy a stand-out.Performance There are five engines available on the BLS saloon comprised of two diesel units and three petrol options. The flagship model is the 255bhp 2.8-litre T V6 petrol unit that would be more at home on a more dynamic car. The BLS has plenty of grunt and can clear 60mph in 6.5 seconds and reach a top speed of 155mph.Emissions It’s the more powerful 177bhp 1.9-litre TiD diesel unit that’s the most efficient and economical in the BLS’s line-up. Despite having an extra 30bhp over the other diesel in the range, the 177bhp unit returns 49mpg and emits 151g/km in CO2 emissions. The 255bhp 2.8-litre petrol engine is more of a drain on funds with emissions of 245g/km and a combined cycle fuel economy of just 27mpg.Driving All versions of the BLS, regardless of engine choice, are fast and fairly powerful which makes them great for motorway cruising and driving at speed. Unfortunately when you have to start twisting and turning in the BLS, its flaws are all too obvious. Around bends there’s plenty of bodyroll despite its fairly sleek profile. Steering is also vague and woolly.Feel The BLS’s handling problems stem from its soft suspension setup which drains fuel and makes for a bouncy, smooth and comfortable ride but one which comes at a detriment to driving enjoyment.Space There’s plenty of space inside the BLS for passengers in the front especially. Those in the rear will find themselves cramped on longer journeys but generally there are no concerns regarding passenger head and legroom. There’s also a 419-litre boot at the rear.Equipment The BLS – like most American models in the UK – is well kitted out with a wide range of equipment and driver features. With just one trim level, rear parking sensors, dual zone climate control and an auto-dimming rear view mirror comes as standard.Price The BLS is not cheap and pricing ranges from £24,203 to more than £32,000 – another reason why it has failed to catch on in the UK.Quality As mentioned, the BLS shares a lot of its design with the Saab 9-3 – whether it’s the saloon or wagon you’re after. That’s most noticeable in the interior where its links with the Swedish manufacturer are obvious and frequent. That’s a ringing endorsement to the American manufacturer based on Saab’s executive heritage and the interior is well put together and favours high-end materials. The downside is that – like its exterior – the BLS’s cabin is a bit dull.Safety The BLS comes with six airbags, active headrests and seatbelt pre-tensioners inside. There’s also a wide range of driver aids under the bonnet.Pros You’re likely to be the only driver in sight driving the Cadillac and it also comes with a high quality interior, decent size and a powerful engine range.Cons It’s expensive for what it is and it looks dull both inside and out.Alternatives Saab 9-3, Volvo S50/V50
