    The New 7 Series BMW

    I know you are probably joking but as long as the front has a reasonably big curve on the sides and top it doesn't influence the drag that much. What is important is to have no details along the car causing the flow to detatch and make the wake bigger - the drag is equal to the momentum loss in...

    Watch collectors - let's talk watches here!

    The ceramic isn't very comfortable and whilst I like the look of it, particularly the meteorite dial I don't wear it often. The Racing Speedmaster lives in the safe since the last one sold went for around £75k, apparently only about a dozen are known to exist :oops:. I am currently wearing a...

    BMW I4 M50 test drive

    The information I have is that BMW were surprised that most customers were so conservative that the innovative i3 and i8 did not sell as well as they expected so they went back and made their future electric cars look like people were used to so a lot of the innovative engineering was dropped. A...

    Watch collectors - let's talk watches here!

    When I got my Speedmaster Professional as a 21st birthday present in 1971 it looked huge compared to almost every other watch available. As fashions have changed watch cases have got bigger and bigger and nowadays the movement is tiny inside vast cases on most watches. I also have a Speedmaster...

    BMW I4 M50 test drive

    The 2-speed gearbox is to give it legs on the autobahn without losing low speed acceleration, which is such an advertising statistic in the US. The BMW has nowhere near the top speed even though it has similar power. Won’t matter at all in a lot of markets, of course.

    BMW I4 M50 test drive

    Nice to see carbon fibre where it should be and not as shiny bits of trim.

    Lotus Eletre

    The biggest problem with all SUVs is aerodynamic drag and weight. EVS are as heavy but can have low overall drag. Drag is frontal area times drag coefficient so even if they get the drag coefficient down (which they almost never do because the shape is inhenently wrong) the overall efficiency is...

    Lotus Eletre

    No, it is a SUV. Sadly the only thing “Lotus” about this vehicle is the badge.

    Watch collectors - let's talk watches here!

    Rolex have been successfully manipulating the collector market for quite a while now by limiting the supply of what are, actually, very nice but mass produced steel cased watches. It has been very successful for them in terms of image and price compared to back when they were readily available...

    Lucid test drive

    I quite like the styling but have no need for a roomy back seat and want good handling. In fact the Taycan is the only new car available that I would consider, if it wasn't for the Taycan I wouldn't buy a new car yet.

    Uninvited Racing Challenges on Public Roads

    The type of "race" the OP refers to doesn't really exist outside North America though does it, we don't have wide straight multi lane roads with loads of traffic lights? OTOH in every fast car I have owned I have had either other fast cars or motorbikes seeing how fast I'll go on country roads...

    Lucid Air reaches 500 miles in real-world 70 mph range test

    Wow, I hadn't realised that. Here and on the continent all fuel stations have both petrol and Diesel.

    Track competition between Taycan CT4S and 911 on Fifth Gear

    Thanks, I've watched it ! Not that surprised the Taycan is quicker than a 911 around a wet Anglesey circuit!

    Watch collectors - let's talk watches here!

    I have an unfashionably small skeleton watch which is also thin, overall just a fraction bigger than the movement. I bought it decades ago though and you don't see small slim watches much in these days of huge watch fashion. I like it a lot but haven't seen anything like it new for a long...

    "Rare Shades celebrates Porsche's long history of loving color" - Article

    The Taycan is an unnecessary impulse purchase for me. If they discontinue something I really like on my spec (like the wheels) and there isn't an alternative I like I will cancel my order.

    "Rare Shades celebrates Porsche's long history of loving color" - Article

    Love this. I am an old bloke and bored rigid by the unadventurous ubiquity of monochrome shades for cars developing over the last 20 or so years. I think PTP is more expensive than it is worth to me personally but with Mamba Green and Frozen Berry there are two unusual colours to stick 2...

    Cross Turismo Turbo S vs. Moose

    Actually a chicane is very similar to the moose test and most circuits have at least one. They were commonly added to as a cheap way of making a circuit with inadequate run-off areas safer. "Common wisdom" for track engineers was to use stiff anti-roll bars for chicanes to improve response but...
