Porsche Mission S: the engine Porsche won't name

Porsche revealed the Mission S without naming the engine, the power or the price. But the car itself gives it away: a rev counter to 8000 rpm, a gear display, a fan from the 917 race car. And the boss said it out loud: "There won't be a BEV on that platform."

Would you choose the Porsche or the flying Tesla?

0–60 mph in 0.81 seconds. Then it climbed a wall, hung upside down, flipped in mid-air and landed. 🚀

This is the new Tesla Roadster, shown live on 15 October at SpaceX's rocket test centre in McGregor, Texas – a 4,000-acre site where a Raptor rocket engine was fired as a pre-show. Nine years after the first prototype in 2017, the car raced up a curved ramp, held on upside down, launched off with its thrusters, spun in the air and landed – then did a "kickflip" over a Cybercab, a Cybertruck, a Semi, a Model Y and a Model 3.

On stage: Franz von Holzhausen (design), Lars Moravy (vehicle engineering) and Elon Musk. Musk's own words: the future promised us flying cars – "Well, not anymore."

🚗 THREE VERSIONS (official, Tesla)
▪️ Performance – "road ready", 2 seats, active aero + multi-mode suction system
▪️ Thrust – "race ready", 2 seats, cold-gas thrusters at the rear, 0–60 mph in under 1 second
▪️ Rocket – "air ready", 1 seat, a full flight system with thrusters all around the car, invite only. Tesla's own words: "So yes, it can fly." Not approved for public road use.

⚙️ HOW IT STICKS TO WALLS
▪️ A fan and ground-sealing system under the car pulls the air out from beneath it – up to 2 G of suction, enough to hold the car upside down even standing still
▪️ Normal tyres give about 1.26 G of grip. With the fans, Tesla says it corners at more than 2 G
▪️ Two fan modes: at low speed it sucks the car down for traction; at high speed it opens the front and rear of the system for more flow under the car
▪️ Two aero modes (high downforce / low drag) and a rear wing that changes its angle automatically on track

🚀 HOW IT FLIES
▪️ Two carbon-overwrapped pressure tanks (COPVs – the type SpaceX uses on its rockets), 600 litres in total, holding about 250 kg of air (Lars Moravy, on stage)
▪️ 10 nozzles: main thrusters in the rear plus attitude-control thrusters around the car, so it can roll and spin "like a rocket"
▪️ Over 80 kN of thrust. The air leaves the four rear thrusters faster than the speed of sound – you can see the "Mach diamonds" in the exhaust
▪️ Tesla says the thrusters produce 4–5 times the force the tyres can
▪️ The thrusters use all-electric actuators and make micro-adjustments in a fraction of a second to keep the car stable in the air

📊 THE NUMBERS
▪️ 0–60 mph (0–97 km/h): 0.81 seconds, run live on stage – Tesla says the production car will be quicker still
▪️ Musk: half a mile in the time other cars need for a quarter mile
▪️ Top speed: over 370 km/h (230+ mph) – Musk's target is "at least halfway to the speed of sound"
▪️ Range: about 480 km (300 miles) (reported)
▪️ Production: 2028 (Musk, on stage)
▪️ Price: not announced yet

🎨 THE DESIGN
▪️ Inspired by the SR-71 spy plane and "cars that transform"
▪️ "Ano White" paint based on rocket coatings – UV and cryogenic protection
▪️ Gold-tinted glass that copies a spacesuit visor, with titanium accents
▪️ Two seats moulded into the chassis to save weight; magnesium, titanium and carbon fibre throughout
▪️ Steer-by-wire yoke, brake-by-wire and throttle-by-wire
▪️ Ultrawhite interior with grey microsuede, a centre touchscreen plus two small displays, doors that open upwards

❓ THE QUESTIONS EVERYONE IS ASKING

▪️ What does it use as "fuel" to fly?
Just air. No rocket fuel, no special propellant. The two tanks are filled with highly compressed air, and the thrusters release it at supersonic speed. The car refills its own tanks – Tesla's words: it will "puff itself up".

▪️ How does it refill the air?
Tesla says the car recharges the tanks itself. Back in 2018 Musk described an electric pump that compresses the air, powered by the car's battery. Tesla has not said how long a refill takes.

▪️ How long can it fly?
Tesla has not said. The air runs out quickly – these are short hops, jumps and flips, not flights from city to city. Engineers outside Tesla estimate only a few seconds of full thrust per tank.

▪️ How big is the battery – is it the 200 kWh?
200 kWh was the figure Tesla gave for the 2017 prototype, when it promised 1,000 km of range. For the new car Tesla has not announced the battery size or the weight. The only range mentioned for 2026 is about 480 km (reported).

▪️ Isn't a big battery too heavy to fly?
The flying does not come from the battery – it comes from the air. Over 80 kN of thrust is the force of roughly 8 tonnes, several times what a typical sports car weighs, so the car can lift for a moment even with a heavy battery. The battery powers the motors, the suction fans and the compressor that refills the tanks.

▪️ Why does it need a big battery at all?
Because everything runs on it: three-digit speeds, 0–60 in under a second, the suction fans that hold the car to the road, and refilling the air tanks after every launch.

▪️ Can it really drive upside down?
Yes – the fans create up to 2 G of suction, so the car pushes itself onto the surface harder than gravity pulls it off.

▪️ Did someone drive it during the demo?
No. For the stunts the car drove itself, "to make sure we don't kill anyone", as Musk put it. The production Roadster will be the only Tesla made to be driven by hand.

▪️ Is it safe and road legal?
Musk said it is "not necessarily a safety-optimised car". The Rocket version is not approved for public roads, and Tesla admits it may not be legal everywhere.

▪️ Can I buy one?
Reservations are open in the USA: $5,000 refundable today, plus $45,000 within 10 days for the Performance version. The Thrust version's reservation is reported at $250,000. Rocket is invite only. Production starts in 2028.

💡 COOL FACT
In 2018 SpaceX launched Elon Musk's original Roadster into space on the first Falcon Heavy – with "Starman" behind the wheel. Tesla's line for the new car: "We already put Roadster in a rocket. Now we put a rocket in Roadster." Next challenge from the stage: a jump over Snake River Canyon, the one Evel Knievel tried in 1974.

Would you reserve one, or is a flying sports car one step too far? 👇

Why LFP Batteries Rarely Catch Fire | Nail Test Explained

Same steel nail, two EV batteries. The nickel (NMC) battery goes past 500 °C and bursts into flames. The LFP battery stays as warm as a hot coffee. The reason is chemistry: in LFP the oxygen is locked inside the cathode, so a fire has much less fuel. Safer, but not fireproof.

Four-wheel drive with no propshaft, and a fuel most people have forgotten about. The cleverest cheap car on sale.

31 minutes with the Dacia Duster Hybrid-G 150 4x4: how the system works, what it is like off tarmac, what it is like on it, and why this particular Duster is a more interesting piece of engineering than its price tag suggests.

The clever part: instead of running a propshaft down the middle of the car, the rear axle is driven electrically. That saves weight, saves cost, and leaves the cabin floor alone. Add LPG capability to the petrol engine and you get a 4x4 that is cheap to buy AND cheap to run — a combination that basically does not exist anywhere else on the market.

The honest criticism: this is not a serious off-roader and Dacia does not pretend it is. The electric rear axle helps you out of a muddy field or up a snowy track — it is not a substitute for a locking differential and proper ground clearance. Buy it for winter confidence and forestry tracks, not for green-laning.

European spec, and LPG availability varies a lot by country — check yours.

Would you run a car on LPG, or has it disappeared where you live?

The Model 3 has no instrument cluster. At night, that stops being a talking point and becomes a simple question: can you see what you need to see?

35 minutes in the Model 3 Long Range RWD after dark: the headlights on unlit roads, the central screen at night, how much light it throws into the cabin, the ambient lighting, and what the car is like to cover distance in when it is quiet.

Why the night drive settles the cluster argument better than any studio shot: in daylight, a screen in the middle is merely unusual. At night, a bright screen sitting in your peripheral vision is either well managed or genuinely tiring. Tesla has had years to tune this and it shows — but you should judge it on a dark road, not in a showroom.

The honest criticism: the screen dims properly and does not glare, so that part works. What still costs you is glance time — your eyes have to leave the road further to check your speed than in a car with a head-up display or a cluster. That is a real ergonomic cost, and no amount of software polish removes it.

European spec.

No instrument cluster: have you got used to it, or would it still stop you buying?
