Tesla graded its own homework. NHTSA wants to see the work.

Good morning. Canada's counter-tariffs went live at 12:01 AM yesterday, Volkswagen sold a car plant to the people who build the Iron Dome, and Tesla put a two-seater with no steering wheel into paid service in Austin. Regulators opened an audit before the first fare cleared.

The connective tissue is who gets to decide a car is legal. Since 1966 the U.S. answer has been the manufacturer, on the honor system, with the government checking the paperwork later. That system just met a vehicle without pedals.

In today's newsletter, we'll get into:

Let’s roll.

This one is in Connecticut, which is close enough to be a problem. I used to own a 2013 750Li, and what I remember is how little effort it asked for: a car that would cover 400 miles without you noticing and still had more than enough under the right foot when you asked. 2013 also matters for the engine. That is the year the N63 got its technical update, with Valvetronic, revised turbos and timing hardware, and a cooling rethink that addressed most of what gave the first version its reputation. Same year, same chassis, updated engine, 140 more horsepower. That is not a listing I can look at casually.

The pitch: Alpina took an F01 7 Series to Buchloe and returned a 540-hp, 538-lb-ft twin-turbo V8 sedan on 21-inch Style 250 wheels, with a body kit that exists to reduce lift rather than to photograph well. The 2013 facelift is the one to have. This car has the build sheet in the gallery, Bang & Olufsen, heated everything, and no modifications beyond window tint. One key. The second Alpina key is in the same drawer as everyone else's second Alpina key.

Now the Carfax, because on an N63-family V8 the Carfax is the whole story. April 2026, 61,285 miles: ignition coils, plugs, and intake and exhaust valve seals replaced. Valve stem seals are the job on this engine. The hot-vee turbo layout cooks them, the car starts drinking oil and smoking on cold start, and the fix is a heads-off, four-figure-plus invoice that most listings describe as "runs great" right up until the PPI. Somebody paid that bill five months ago and then listed the car. That is the best sentence in the listing and it is buried in the service section.

Against it: an October 2013 left-side accident with no airbag deployment, front-end chips, one curb-rashed wheel, and bolster creases. The accident was a first-year event on a car that has since covered 60,000 miles, so the question is paint depth, not structure.

Tesla started charging fares for Cybercab rides in Austin on Thursday. No livestream, no stage, no remarks; shareholders and friendly influencers rode first, reportedly under NDA. Later that day, NHTSA opened Audit Query AQ26002 covering an estimated 1,000 vehicles.

The audit is not about a crash or a defect. It is about paperwork, which is why it matters more than a crash would.

Under 49 CFR Part 571, U.S. automakers do not get cars approved before sale. They certify, themselves, that the vehicle meets every applicable Federal Motor Vehicle Safety Standard, and attach the label. NHTSA audits later. The honor system has worked for sixty years because every car had a steering wheel and nobody had to interpret the word "applicable."

The Cybercab has no steering wheel, no pedals, and no mirrors. Tesla's position is that it complies with every standard that applies to a car lacking those parts. NHTSA's question is how much of that certification rested on Tesla deciding certain standards were inapplicable. Translated out of federal register: you decided which rules didn't apply to you, and we'd like to see the memo.

There was another door. Part 555 lets a manufacturer petition for temporary exemptions from specific standards. Zoox, from issue #8, went that way: self-certified in 2022, drew a special order and then an audit query of exactly this type, and ended up in July with eight exemptions covering 2,500 vehicles for two years. Four years of process. Tesla looked at that timeline and chose the faster door. The audit opened before the first ride ended, which suggests the agency had the filing drafted.

Two things make this different from the usual Tesla-versus-NHTSA cycle. DOT has already proposed dropping manual-control requirements for purpose-built autonomous vehicles, so Tesla is betting the agency won't enforce a rule it is publicly trying to delete. And the Cybercab runs software closely related to Full Self-Driving, which sits under a separate probe covering about 3.2 million vehicles. Both questions are open at the same agency at the same time.

I have sat in enough design reviews arguing whether a requirement applied to our part or someone else's to know that "inapplicable" is the most expensive word in a compliance document. It is also, sometimes, correct. An audit is where that gets settled.

Analogue Automotive has delivered the first customer VHPK: a Series 1 Lotus Elise rebuilt around a central driving position, a carbon body, and a 250-hp Rover K-series. Wet weight is under 600 kg. Price is £350,000 plus taxes, 35 will be built, and the commissioning customer is a Hong Kong collector whose initials are the last two letters of the name. The budget was not the constraint.

The interesting engineering decision is the one they didn't make.

Anyone who has priced an Elise build knows the default move: pull the K-series, drop in a Honda K20, enjoy VTEC and a gearbox that doesn't hate you. The swap is so common it is practically a factory option. Analogue walked away because the Honda powertrain is roughly twice the mass. On a 700-kg car that is a whole-car decision. Every kilogram behind the driver's shoulders moves the polar moment, loads the rear tires, and pushes spring rates up to compensate. You end up re-engineering the chassis around the engine you picked for convenience.

So they kept the K-series and made it earn its place. Displacement went from 1.8 to 1.9 liters, the internals are billet and forged, individual throttle bodies replace the plenum, and MoTeC runs it. Peak torque is 185 lb-ft at 5,800 rpm, up from 122 in a stock S1. The rear luggage bay is gone because the airbox lives there now. The head gasket, the K-series' most famous personality trait, is presumably a solved problem at this price.

The mass budget is worked everywhere else. Carbon panels at roughly half the weight of the original fiberglass. Bespoke 15/16-inch wheels in the original split-spoke style rather than upsizing to fit bigger brakes. And 300-mm carbon discs on four-piston AP calipers, each rotor saving 2.6 kg against the stock cast-iron part. That matters more than it sounds: a brake disc is unsprung and rotating at once, so every kilogram you remove pays twice.

Then the seat. Moving the driver to the center puts you in McLaren F1 and GMA T.50 company, and it is not a styling call: symmetric sightlines, symmetric mass, no passenger loading one side. The gear-lever landed on the driver's left because the gearbox sits on the left end of the transverse engine and the shortest linkage wins.

The dynamic consequence is the part I find most satisfying: because the car got lighter, the springs got softer. Analogue dropped the rates and re-valved the dampers versus its own SuperSport, and the lighter car reportedly rides bad tarmac better. Less mass means less energy to control, which means less stiffness needed to control it. Every modern hypercar runs this backwards on purpose: add a hybrid system, then add spring rate to manage the hybrid system.

This morning's Alpina stickered at roughly $131,000 in 2013. The public sales record for the F01 B7 now shows an average of $27,323, a high of $48,000 set in May 2022 by a 2013 xDrive, and a floor of $10,000 set this past July by a 2012 car. A standard 750i xDrive of the same vintage trades in the high teens at similar mileage.

So the Alpina premium is still real in dollars, roughly $8,000 to $12,000 over the donor car. In percentage terms the badge kept about 20% of sticker while the donor kept about 15%. Slower depreciation, but not dramatically, and not what the reputation suggests. Three forces are at work.

Volume. Alpina built the F01 B7 in the low thousands for the U.S. across five model years. Rare enough to feel special, common enough that a buyer can always find another. Scarcity premiums need a shortage, and there isn't one yet.

The maintenance floor. Valve seals, coils, 21-inch tires, and the cooling system on a hot-vee V8 set an ownership cost that does not fall with the purchase price. At $10,000 the car is worth less than its next big service. That is what a floor looks like in practice: the point where the next invoice exceeds the resale, and the car either finds an owner who does the work or leaves the market.

The Buchloe question. BMW acquired the Alpina brand in 2022 and officially took full control of the brand at the start of 2026. The independent Bovensiepen-era cars ended with the 2025 model year. Every F01 B7 was built by the company that made the name mean something. The market has not decided whether that matters. The R129 in issue #14 spent two decades at the bottom of its bathtub before generational rotation pulled it up. The F01 B7 is at the bottom now, with a 2022 high-water mark nobody has touched since.
