    [opinion] - hmmm…VW/Audi/Porsche may be in trouble…

    No it is not. Not here anyway. The biggest difference is in the standard equipment many of the most expensive options are standard on Turbo S and the J1 turbo S is unique in having a 600A front inverter. I don't need the performance anyway, my CT4S has all the overtaking capacity I have so far...

    Indeed. EVs are daily drivers. Too heavy for racing, and road targeted versions not got the thermal capacity.

    The lecturer in Electrical engineering in my degree course at Imperial College, London (in 1969) was an old boy who had been involved in the design of several of the traction systems in the London Underground railway. All exam questions were about rating motors to be just good enough for the...

    My concern is that for a customer like me they need to be very cheap if they are like that because their useful life will be more like a phone or computer than a car. I still have 2 cars bought new now over 20 years old that still do everything I want, some things better than modern cars. Their...

    AFAIK Trump has never been involved in motor sport. It is a matter of due process really and so nobody can be sure what may happen to them. I have visited the US probably close to 100 times for work, holiday and visiting friends but won't come again.

    Certainly won't be visiting the USA at the moment!

    Probably, and any difference will probably be negligible to 99.99% of all drivers, whatever they think ;)

    The Lucid isn't available in most places, including the UK, so probably only a side interest to a UK magazine. There are hardly any light cars any more and Porsches are not particularly light any more and getting good throttle response and an exciting sound eliminates turbo engines, so most IC...

    It is much cheaper and easier to add more motors you already make to get the power for a statement model than design, tool and manufacture a bigger one for a small production run. 2 motors on an axle give more freedom on how you implement torque vectoring. It may be easier to cool 3 small...

    It is the total power that counts, not how many motors.

    A high top speed is one of the easiest parameters to achieve. It just needs power and, preferably, low drag. Doing it whilst retaining dynamic stability and brakes is the difficult bit.

    Yes but one you describe has never been proposed by any practical engineer ;)

    You need to read what was written more carefully before replying. The point was about how much energy is needed to refine a litre of petrol and distribute it. Not how much energy burning it can release. Yes whilst the proportions have got slightly more favourable using turbochargers and hybrid...

    I don't know which EVs run their motors hot enough for long enough to damage their lubricants, but I haven't done a search. Of course if you only burn pure oxygen and pure hydrogen you won't get NOx but I have never seen that seriously proposed. Most IC engines get their oxygen from the air -...

    I completely agree, this company was doing research near Banbury but the production plant was planned next to a hydro dam in Scotland. I was intrigued to see recently that around 40% of all (very polluting) cargo ships on the ocean are transporting fossil fuels, oil, coal and gas so anything...

    [opinion] - hmmm…VW/Audi/Porsche may be in trouble…

    Absolutely, much of the pollution is inherent in the IC engine, not the fuel's origin. It also means the (as yet non-existent) green hydrogen powered vehicles are only really clean using fuel cells producing electricity for an electric motor not burning it. In an IC engine it retains many the...

    One of my ex-colleagues who has worked for the last few years for a R&D company making synthetic petrol has just been told he will be made redundant since they can not raise the investment needed to continue. Whether it is the projected cost which puts investors off or the time scale to...

    Watch collectors - let's talk watches here!

    Given the film has been heavily supported by some in F1, particularly Lewis Hamilton, and IWC have been long term sponsors of Mercedes in F1 they probably thought having exposure in a heavily marketed film may work out well, like James Bond watches and so on, there is quite a history of watches...

    Propaganda works. The oil industry makes a billion dollars a day so can easily fund and help along the misinformation if it is to their financial benefit. Brexit relied on people believing propaganda rather than expert advice and the evidence post Brexit is that the experts were right and the...

    Tesla offers blended braking (regen when pressing the brake pedal)

    I started working in racing in the 1970s when we still had 3 pedals and driver skill with the gearbox in terms of not damaging it and not missing shifts - the difficulty of changing gear and driving an engine with difficult throttle response was the main reason we had overtaking back then - not...
