1960 models received a front anti roll bar along with hydraulic steering damper.

For 1961, significant technical advances occurred in the form of a new engine and transmission.
The engine remained at 1,192 cc (1.2 L; 72.7 cu in) but the power increased to 40 bhp (41 PS; 30 kW) at 3900 rpm and 88 N⋅m (65 lb⋅ft) at 2400 rpm of torque primarily due to an increase in compression ratio to 7.1:1.
The single-barrel Solex carburetor received an electric automatic choke and the transmission was now synchronized on all forward gears.
The traditional semaphore turn signals were replaced by conventional flashing directional indicators worldwide.
The standard model called the TYPE 111–112, continued to use the 36 hp 1200 engine of the old architecture that dates back to Franz Reimspiess original design of 1937 all the way until the end of the 1965 model year.
1965 standard model in 1965 is called the "A" sedan.

For 1962, the Beetle received a mechanical fuel level gauge in place of the former fuel tap.
The Standard model continued without a gas gauge until the end of the 1965 model year.
At the rear, larger tail lights were introduced incorporating a separate amber turn signal section to meet new European standards (these turn signals remained red in the US market until 1973).
The former hand-pump style windscreen washer was replaced by a new design using compressed air.
A Schrader valve located on the washer fluid tank allowed the system to be charged at a filling station to the recommended 35 psi (2.4 bar).

1964 models could be identified by a widened light housing on the engine lid over the rear license plate, however the standard model continued to use the old teardrop style to the end of the 1965 model run.

The largest change to date for the Beetle was in 1965: the majority of the body stampings were revised, which allowed for significantly larger windows.
The windshield increased in area by 11% and was now slightly curved, rather than flat.
Door windows increased accordingly by 6% (and door vent window edges were canted slightly back), rear side windows 17.5%, and the rear window 19.5%.
The result was a more open, airy, modern look.

For 1966, the big news was an optional new 1300cc 50 hp (37 kW; 51 PS) engine in lieu of the previous 1200cc engine that had been the sole engine since 1954.
Models so equipped carried a "1300" badge on the engine lid.
The 1300cc engine was standard for North America.

For 1967, a yet-again larger-displacement engine was made available: 1500cc, 53 hp (40 kW; 54 PS) at 4,200 rpm.
1200 and 1300 engines continued to be available, as many markets based their taxation on engine size.
1500cc Beetles were equipped with front disc brakes and were identified with a "VW 1500" badge on the engine lid.
North America received the 1500 engine as standard equipment, but did not receive front disc brakes.
These models were identified by a "Volkswagen" badge on the engine lid.

The rear suspension was significantly revised and included a widened track, softer torsion bars and the addition of a unique Z-configuration equalizing torsion spring.
On US, UK and Ireland models, the generator output was increased from 180 to 360 watts, and the entire electrical system was upgraded from 6 to 12 volts.
The clutch disc also increased in size and changes were made to the flywheel.
New equipment included a driver's armrest on the door and locking buttons on both doors.
Safety improvements included two-speed windscreen wipers, reversing lights (in some markets), and a driver's side mirror.
In accord with the newly enacted US Federal Motor Vehicle Safety Standard 108, North American models received a dual-circuit brake system, the clear glass headlamp covers were deleted; the headlamps were brought forward to the leading edge of the front fenders, and the sealed-beam units were exposed and surrounded by chrome bezels.
In the rest of the world markets the 1967 model retained the older headlights.
Another oddity of the 1967 North American market Beetle is the rear bumper overriders (towel rails) – the overriders have a different shap
