Porsche 963 RSP is a one-off racer for the road

This road-legal racer was inspired by a similar version of the Le Mans-winning Porsche 917 built 50 years ago.
Porsche has created a road-legal version of its 963 hypercar. That's the machine vying to win this year's 24 Hours of Le Mans.
Only one Porsche 963 RSP has been produced. It is inspired by a similar one-off, road-legal version of the two-time Le Mans-winning Porsche 917 race car. The German company made that one 50 years ago.
Porsche ensured the historic car was road legal by adding a set of exhaust silencers, extra mirrors, side indicators and a horn.
However, the modifications are slightly more significant for the 963. The lightweight CF bodywork was painted in the same Martini Silver hue as the Porsche 917 race car. On the nose is an enamel Porsche badge, rather than a sticker. New vents adorn the front wings and a unique 3D printed badge they applied to the rear light bar.
Forged OZ racing wheels are wrapped in 18-inch Michelin tyres with a seventies-era logo added. Inside is a bespoke, hand-made interior featuring tan leather and Alcantara upholstery. Carbon seats are air-conditioned, like the 963 race car's.
Under the hood?
The Porsche 963 RSP features a race-tuned 500kW hybrid powertrain. At its heart is a 4.6-litre V8 engine from the Porsche 918 Spyder supercar, boosted by two turbochargers. It can spin to over 8000rpm. The motor was remapped to make power delivery smoother and to permit the use of regular petrol.
The solitary 963 RSP was commissioned by Roger Penske, whose initials 'RSP' give the car its name. The Porsche Penske Motorsport team won both the IMSA WeatherTech SportsCar Championship and World Endurance Championship with the 963 last year. It is bringing three cars along to compete in Le Mans.
The Porsche 963 RSP will make its public debut at the Circuit de la Sarthe during the 24 Hours of Le Mans, before returning to the Porsche Museum in Stuttgart.
In July, the car will participate in the Goodwood Festival of Speed, along with the 917.

2025 Porsche 911 Carrera GTS Review

The 911 rallies yet again in its 992.2 generation, adding electrification to its bag of tricks. Is the Carrera GTS still a divine choice? The endless evolution of the 911 continues with the 992.2 series GTS, the first rear-engined hybrid road car from Porsche. It's best to think of it as electrified rather than a hybrid; that makes it sound like some economy special. This performance hybrid produces improved power and delivery, while ensuring it uses roughly the same amount of fossil fuel the old one burnt. What's all the fuss about? The Carrera GTS has both a new high voltage electrical system and a fresh 3.6 litre engine. The electric bits include a 400V architecture with a 1.9kWh (27kg) battery stored up front. That powers a 40kW/150Nm motor living within the beefed up eight-speed dual-clutch trans (stronger clutches and gear sets). This adds its torque from idle to help improve initial response. The battery also feeds the flat six's new electric turbo, which has a motor positioned between the compressor and turbine wheel to get it spooling quickly, reducing lag. Where the previous engine was a twin turbo, this one can make do with one larger unit without the associated lag of a big blower. Some other advantages of going hybrid include an electric air conditioning compressor (no belts means a more compact engine) and there's no need for a starter motor. The engine makes 357kW and 570Nm, while total output is 398kW and 610Nm. That's up 45kW and 40Nm, while the hybrid bits add around 50kg. Consumption for the old GTS was 11.3L/100km, now it's stated at 10.7. They didn't do much to the chassis, though RWS is now standard, teaming with adaptive dampers and Porsche's torque vectoring plus system. The look changes with the lower apron adopting those big flaps. They close off to improve aeros while opening when more cooling is needed for the radiators in behind. The headlights are new, incorporating all the lighting sources up front while the rear end has been remodeled. The rear lid vents feed the intercooler on top of the engine. There's a GTS-specific sports exhaust system as standard. Goes hard This is jet quick with the 0-100km/h taking a claimed 3.0sec, the 80-120 just 1.9sec. The launch is flawless, easily initiated too, something you'll have to demonstrate to your cronies when exiting the golf club. This hybrid six adds pace quickly as the torque spews forth. Porsche says it's already making 500Nm at 1500rpm and the full whack is on from 2000rpm. This feels more like a large capacity, naturally aspirated engine. The delivery is truly linear, with masses of torque on tap low down and into the midrange while a big serve of power awaits up high. While there's not that whip crack response of a honed, naturally-aspirated mill, the action is smart, and lag-free. With new solid roller cam followers (less friction and more robust when stretched) the 3.6 spins freely. It sounds great too, the GTS-specific sports exhaust extracting a melodious mechanical snarl that works to cancel out the road noise. If you are merely cruising in this, the tyres make quite the rumble on coarse chip. This new hybrid engine adds to the 911's great chassis. You need just a hint of steering to get it turning in sweetly, while it's stable in the sweepers yet quick to change direction as well. There's a sniff of understeer during tortuous cornering. By understeer we mean the front tyres merely shuffle a smidge off the perfect line. But then the G metre was registering 1.41. It's all well communicated and sorted with a whiff less gas. The rears manage the ample flow of torque but aren't immune to its effects. Too much gas can arouse the TC's attention out of tighter turns. But get it right and the power helps it round off the bend sweetly. We should have prodded the DSC into Sport mode to give the rear some leeway. However, that's probably better left for track antics. The transmission is reference grade. There are paddles but you won't be as good. And the brakes are a class act too, the pedal action and stopping power ace. The drive mode switch remains on the wheel (the best place for it in a sports car) while there is a switch on the dash to toggle between the Normal and Sport damper settings. Sport is a little bumpier for sure but also more precise and never overly harsh. If you want to activate the sports exhaust (yes please) or raise the rear wing (go on, you bogan) you'll do so via the touchscreen. Still the everyday sportscars At the other end of the tacho spectrum, the Carrera GTS is happy to lug around in tall gears with just 1000rpm on the dial. And it pulls without hesitation too, no untoward vibration or jerkiness like we noted the previous GTS doing. It's so unstressed at sedate cruising paces. It'll chug up a decent incline on the motorway at 1100rpm in eighth easily. The idle stop is seamless, the engine conking out before you come to a halt but there's no electric drive; it's not that type of hybrid. As to fuel use, it all depends on how you drive it. We saw 19.9L/100km doing our worst, the long term average was in the 15s, while sedate motorway/highway cruising can net high single figures. Inside, the few changes include the loss of the analogue tacho, the instruments now fully digital with various displays. Storage remains sparse, though there's a wireless charging tray in the centre console bin, and that's about all there is room for. They really need to reconfigure the centre console; the designers should move the gear selector to free up space. Ride quality is good for a big-wheeled sportster but the creaks and rattles from the cabin we could do without. This hybrid has the same boot capacity as the other models, which is not much, just enough really. The rear-wheel steering makes parking easier, there's a good surround-view camera, the active cruise works all okay and the safety alerts are minimal (once you remove the lane departure warning). A front end lifter is a cost option but probably a necessity to keep the front spoiler clean. One downer is the price. Porsche has never been a value brand but recent price rises have the brows rising. The 2022 GTS we drove had a base of $289,900 while this new one kicks off at $367,900. That said, it does have a higher standard specification. If you were to put a positive spin on it, it's slightly better value than the revised GT3, which is now $435k, and the GTS is quicker.

Photo: AFP New Zealander Earl Bamber will start from two on the grid for the 24 Hours of Le Mans race, with Cadillac locking out the front row in qualifying. Britain's Alex Lynn secured pole position, setting a best time of three minutes 23.166 seconds in the number 12 Team Jota Cadillac at the Sarthe circuit Bamber putting the sister 38 car alongside and 0.167 slower. Bamber has won the race twice, in 2015 and 2017 with Porsche. Fellow Kiwi Brendon Hartley, who has won the event three times, will start from 10 on the grid after team-mate Sebastien Buemi locked up the Toyota Gazoo car and drove into the gravel and was not able to finish the qualifier Lynn shares his car with compatriot Will Stevens and Frenchman Norman Nato while Bamber's teammates are 2009 Formula One world champion Jenson Button and French four-times Champ Car champion Sebastien Bourdais. "I can't tell you how much I wanted this," said Lynn, who missed out on pole last year by a mere 0.138, over the team radio. "One tenth last year hurt a lot. "I'm truly honoured to be able to put in a performance like that in front of everyone and deliver for Cadillac in the way they deserve," he added after getting out of the car. "This is a magical circuit and this is a special feeling. I can't describe it. We will enjoy this tonight, have a good sleep and re-set." GM-owned Cadillac are the first American marque to take outright pole at Le Mans since Ford in 1967. The number five Porsche Penske was third fastest, after threatening to take pole, with France's Julien Andlauer, Denmark's Michael Christensen and France's Mathieu Jaminet. The number 15 BMW qualified in fourth place with Belgian Dries Vanthoor, Swiss-Italian Raffaele Marciello and Danish former F1 driver Kevin Magnussen. Defending champions Ferrari, outright winners for the past two years, had Italian Antonio Fuoco, Denmark's Nicklas Nielsen and Spaniard Miguel Molina in seventh place in last year's winning car number 50. The 93rd edition of the race starts on Sunday at 2am NZT. - Reuters/RNZ Sport
